    HPH347: Common pitfalls to avoid when building a house – with Amelia Lee

    Amelia Lee from Undercover Architect shares some common themes that tend to crop up on owner-builder projects (particularly with people who are doing this for the first time) and explains how they can be avoided by creating a clear foundation of your values and project intentions.

    Interview with Amelia Lee

    This is the second of Ben Adam-Smith’s interviews from his time in Australia and in this episode we have a chat Amelia Lee from Undercover Architect. Amelia has been an architect for 30 years and in that time worked on wide range of different projects, as well as three of her own renovations. 10 years ago she decided that she wanted to expand her reach to help more people and left her practice to start Undercover Architect as a platform to provide educational resources that help inform and empower new owner-builders (‘self-builders’ in the UK). In that time she has built a community of confident owner-builders that are well resourced to advocate for sustainable building practices and create homes that help them live well.

    In this chat, Amelia and Ben compare their experiences of working with people who want to build new or renovate existing dwellings, and identify the most common challenges that occur.

    Don’t rush the planing stages!

    Many people focus on the build stage of a project, but there are 3 crucial stages before you get there which will determine the success of your build.

    There a 4 phases to any project:

    1. Pre-design
    2. Design
    3. Pre-build
    4. Build

    Amelia emphasises that the more work you can do in those first three phases to anticipate and manage the potential risks, the more likely your build will go according to plan. Any changes or delays that happen during the build stage will be very costly so having a good plan in place will help your team work as efficiently as possible.

    Pre-design

    The pre-design stage forms the background research for your project. You will need to work out your local planning regulations, the limitations of your site and any council requirements that will need to be considered.

    Lots of people turn to neighbours or friends for advice on these things and then call it a day, but it is very important that you work out the bigger picture of your construction climate. Amelia explains that some councils in Australia allow owner-builders to fast track their projects through planning if their design meets certain requirements, so knowing these things will help you mould your building design to receive local support and avoid potential obstacles.

    “It’s like playing any game, when you find out the rules first, you can create the greatest strategy in order to be able to be most expeditious and efficient in how you do things.”

    Get to know your budget

    This stage is also where you figure out your budget. The budget must be revisited at every stage, but it is most important to start with a good understanding of what you have available so that anything you take on from this point will be working in accordance with this.

    Establish your values

    You also need to work out what you want to achieve and establish your values that will create the foundations of your design. What are your big picture goals? How do you want your house to work for you?

    “You will need to make something like 15,000 decisions. This gives you some way to anchor yourself to and check against to guide the decision making overall so you don’t get lost in the process.”

    Design

    The design phase is about figuring out how these spaces, places and rooms are going to work best for you. How do you need the house to function best for you?

    Your current home can tell you a lot about your future one

    You can begin to work this out by analysing your current home, looking at which bits work well for you – maybe you like how your kitchen is close to the front door so you can unpack your shopping easily or that your living room faces south so is always full of light. But also working out which parts don’t work for you, like the separate dingy dining room that becomes a dumping ground. Knowing how you want to use a space will help you create a design that works best for you.

    The orientation of your site is important to know

    Amelia explains that understanding the orientation of your site and working out how your house could sit best within it will allow you to optimise the liveability. By considering the positioning, the climate, neighbouring properties, surroundings and even a nice view or feature that you would like to showcase, you begin to create signposts for your design. Knowing these factors can also help to increase energy efficiency by utilising solar gains for heating or natural shading features that can help with cooling.

    Explore the different construction methods available

    In this phase it is also really important to explore all the construction and design options out there so you can pick the one that best meets the requirements you outlined in the pre-design stage. It can be easy to fall into the trap of following the standard or most common construction path, but this might not be the best path for you and your build.

    Always keep one eye on your budget to make sure you are still on track!

    The design stage will start giving you an idea of the cost of your project, make sure you are sticking to your budget and checking that you can afford what you are planning.

    “Your budget is going to dictate the size of your house right from the outset and the level of finish that you can expect. If it’s not going to be enough, then you need to figure out if you need to find more money? Or do you have to radically reduce the size of our property before we begin?”

    Pre-build

    The Pre-build phase is all about formulating your practical construction plan and assembling your team. This will include looking at your building approvals, finalising your building materials and construction methods and collating all of your documentation. In this section, you will need to keep referring to the values you established right at the beginning and make sure you are making decisions that are in alignment with those.

    Create a clear plan for your build

    This stage should focus on formulating a comprehensive build plan with detailed drawings and specifications that will hopefully reduce the need for you to make quick and maybe uniformed decisions under pressure.

    “Drawings, specifications, those kinds of things are the language with which the construction industry understands how things get done, and so the more you can put into that information is super important.”

    Test your energy efficiency now

    Make sure you spend some time testing the energy efficiency of your design, pre-build. PHPP will be very useful at this stage to test the functionality and provide a picture of the energy movement in your design before you have it set in stone… or timber.

    Assemble your dream team

    Choosing your team is very important – trust your gut and pick people who align with your values or have experience in what you are aiming to achieve. Remember, these people will be in your life for anywhere from a few months to a few years!

    Build

    This stage will involve spending the most money and watching the physical progress of your build but if you have completed the first three stages well, this should go pretty smoothly. Of course, there will always be a few hiccups along the way which you can’t predict, but the structure and values that you have created should help you navigate these with ease.

    Key things to remember here are to be as present as possible and make sure that you are referring back to your values when obstacles arise.

    Work out an accurate budget and stick to it

    A clear and realistic budget is very important in a build project. Amelia explains that in her 30 year career most of her clients have a budget that is 50 – 75% of where it needs to be to match their initial aspirations for their home. This figure has tracked consistently regardless of price rises in construction due to inflation, covid, etc. Being realistic about what you can get for your money and making sure you are including all costs (such as planning application fees, landscaping costs, internal finishes, etc) in your budget is crucial.

    Your team can help you predict your costs

    It can be a good idea to work with someone who has experience in the specifics of your build, so you know that they have some knowledge of how much it is likely to cost. It can be useful to include your builder in the design process as a consultant, in order to get a realistic idea of the cost whilst you still have time to amend designs.

    If you are working with someone who isn’t experienced with Passivhaus or sustainable building, Amelia recommends building in a 20-30% contingency into the budget as the cost of certain processes will probably be more than they have accounted for.

    “Your builder can actually be providing input on cost and buildability from the outset, and that includes at that very first meeting, when you say my budget is x, and I want to do y. The builder and the architect can sit there and say, well, from our previous projects, we know that the y that you’re asking for, it traditionally will cost this amount per square metre based on these kinds of finishes. Or if you want to do these kinds of finishes, it’ll cost this amount.”

    Don’t feel the need to max out your budget

    Owner-builders often push their budgets to the absolute max and this trend seems to be regardless of starting budget. Like many things in life, the bigger the budget, the more we try and do, which is consistently meaning people take it right up to the limit. In the planning stages, work out a realistic budget if you can and if you don’t have enough, work out if you can downsize the footprint or some way to reduce the cost.

    Amelia does point out that there are occasions where adding an extra bedroom to increase the property value, will also increase the build costs but may allow you to secure a higher loan to build with. Because of the way the housing market and financial services work, there might be creative solutions to be found but definitely try and work out what’s best for you.

    “My experience with homeowners doing their own homes, is that they will spend the most amount of money that they can without financially crippling themselves.”

    Your project starts with you

    Many people think that their project will begin when they have hired an architect or designer and therefore might put off doing so until they are ‘ready’. Amelia highlights that there are several steps you can take prior to this which include exploring how you want your house to function and establishing the values of your project. This may need to happen before you hire anyone as these will dictate who you are looking for, in regards to their experience, ethos and general practice.

    Amelia notes that it is crucial to be asking the right questions when meeting potential architects and designers. Rather than attempting to gain as much free information about your project as possible, try to get to know as much as you can about them and their practices.

    “Who is this person? What are they like? How do they run their business? How professional are they? What do they communicate like? Are you going to be able to handle having this person in your life for the next 12 months to two years? Are you aligned in the goals you operate your life with? And how are they going to best support you in navigating something you’ve never done before?”

    Don’t fall into the trap of the status quo

    It can often feel like the standard formula for house building is to prioritise size over quality. Amelia explains that when her clients spend time thinking frankly about who they are and how they want to live in their future home, they end up realising that they need less space than they initially thought. As a result they get their rooms and budgets working far harder for them and it sets them up to find the right people to support them in that journey as well.

    “One of my big, hairy, audacious goals is for everybody to build a site specific response. It’s how you create climate resilience, climate sensitivity, you improve the energy efficiency of your home, you lower its energy, heating and cooling costs, and most of all, you actually make it a better home to live in for yourself personally. The thing is that most of our housing stock doesn’t do this, so most people are living without that experience on a day to day basis. They just don’t understand from a firsthand point of view, the incredible difference it makes the everyday life to live in a house that works for your site.”

    Creating a design that maximises these things will help you follow the principles of Sarah Susanka and utilise every space in your house, everyday.

    Sustainability must be a foundational theme for it to be effective

    Sticking to your sustainable goals in an industry that has not embraced them yet can be quite challenging. It is all too common for it to fall by the wayside when clients hit a professional in the industry who says sustainability will just cost you more. It’s not the job of your professional to tell you it’s too expensive. It’s up to them to tell you what your choices will mean and cost, and you to decide what your priorities and values are. By assembling the right team and putting in the work in the early stages, you will be much more likely to succeed with your sustainability goals.

    Sustainability Bolt-ons

    Too often in house building we see sustainability advertised as a bolt on service. Amelia views this approach as a form of greenwashing in the industry, as it creates a false economy by giving people a free pass to design oversized and inefficient houses that are perceived as sustainable because they have solar panels on the roof.

    “We’re all living on a planet and we know our choices, impact everyone in everything that we do. Building a house is no different and you’re embedding those choices for a very long time.”

    It is important to view sustainability as a foundational concept in your design, so that the entire structure can be created with this in mind. It is crucial to not get distracted from this goal because the end product will not only improve the sustainability of your home, but also improve the way you get to live in it.

    “I feel that sustainability actually starts and is most heavily impacted in the decisions that you make before you begin, about the size of the project that you’re going to build and in how you’re going to make it suit its climate. If you can get those two things right, you will be 80% of the way there before you even start worrying about solar power”

    Don’t outsource your agency

    Amelia’s closing reflections highlight the importance of being an informed and confident owner-builder:

    “I really encourage people to not to not outsource their agency. At the end of the day, it’s your home, and so no one’s going to care as much about it as you do. I want you to know that you unlock what is possible for your future home because it’s your decisions, your money, your vision, that’s the reason this whole project is happening. So it’s really important that you get yourself educated and informed before you begin.”

    The journey can be a great opportunity for personal growth:

    “I love with empowering homeowners, particularly women who are stepping into a male dominated industry. In the renovation and construction industry, women are making 80% of the purchasing decisions and yet they’re dealing with mostly men as they do this. I see them get to the end of their project, and they turn around and look at what they’ve been able to accomplish for their family and consider what else they are capable of? I just get really excited about what it unlocks for people in terms of readjusting their expectations of themselves as well.”

  • HPH250 : 10 inspiring self builds – with Ben Adam-Smith

    HPH250 : 10 inspiring self builds – with Ben Adam-Smith

    To celebrate our 250th podcast, Ben Adam-Smith picks out ten of his favourite new build homes. These are all homes he has visited and which have impressed him in different ways.

    1. Dundon Passivhaus

    Architect Graham Bizley and interior designer Emily Bizley have produced a magnificent, modern family home that takes in all of the surrounding countryside.

    There are some fantastic spaces in here and the timber theme flows effortlessly from outside to inside. Graham and Emily also did a lot of the work themselves – true craftsmanship – and this tailors the home perfectly to them.

    2. Treehouse

    Video from Homebuilding & Renovating

    While the finished house may look happily aloft, there were plenty of highs and lows for Jon Martin and Noreen Jaafar. They bought this plot without planning permission, even though the local planning authority said it would never get approval. Needless to say they got the green light!

    Then there is the technical challenge of building amongst mature trees. They used pile foundations which carefully stepped around the root structure! Oh, and let’s not forget that they used no concrete on the build. Even running out of money they pushed on to secure Passivhaus certification. A truly remarkable home.

    3. Fran Bradshaw’s house

    Located on the Norfolk coast this is a labour of love for architect Fran Bradshaw. There are beautiful materials – straw bales, thatch, lime render, clay plaster, timber – which pair up nicely with the home’s high performance credentials.

    4. The Autonomous House

    Mike Coe and Lizzie Stoodley went all out on this project to create an ultra low energy eco-build. The heat demand for this house is a tiny 4kWh per m2 per year. It brings all the services in house, so there’s no mains water or mains drainage. Instead rainwater is harvested from the roof and stored in large tanks (recycled orange juice containers) under the house. There are composting toilets, within the thermal envelope. And a PV array supplies the electricity.

    Mike and Lizzie, however, did not stay as long as they intended. Driven by how the climate is changing they decided to move further north to the Isle of Skye… and tackle their second self build!

    5. The Cut

    Self-builders Tara Murphy and Dimitri Daras spent their money wisely here. It’s another example of how a house with a simple form doesn’t have to be boring. On the contrary it is striking.

    Tara also specified a lot of the house with a baby in tow!

    6. Ashley Vale

    Yes, this is not strictly a self build but community-led housing. It got a place on this list for a few reasons. It’s inspired so many other community-driven projects as this was one of the early ones.

    They also managed to wrangle the land away from a volume house-builder, which is an incredible feat.

    And at the end of it all, one of their key players Jackson Moulding went on to set up Ecomotive, to empower other groups to do exactly the same.

    7. Lansdowne Drive

    Architect Bernard Tulkens was behind this project. It’s a modest house that embraces simplicity. The cross-laminated timber structure is exposed as is the ventilation ducting, but it works a treat.

    Throughout the building they have tried to make as much use as they can of recycled, reclaimed and other materials that have low embodied energy.

    And from a Passivhaus point of view there were plenty of challenges… three storey Victorian homes completely overshadow them on the south side. Therefore their West-facing glazing has to be carefully controlled with blinds.

    8. Hampshire Passivhaus

    Architect Ruth Butler perhaps took on a site that others would dismiss. It was a brownfield site that is overlooked by 13 neighbours. So her constraint-led design would need to rise to the challenge.

    And it certainly does. A wonderful contemporary home that feels extremely private from the inside.

    9. Buckinghamshire Passivhaus

    This was one of the UK’s first Passivhaus Plus projects. The architect, Jae Cotterell, was also supplying the build system (PH15). It recorded an outstanding airtightness result of 0.07 ach@50Pa.

    A large solar PV, beautifully integrated, helps them deal with a lot of their energy needs before the surplus is exported.

    10. Chiswick Eco Lodge

    Architect Richard Dudzicki delivered this project for client Oliver Smallman. Oliver lived in a Victorian house next door and had built this property to rent out. But, he liked it so much, after renting it out for a couple of years he decided to move in.

    This house feels wonderfully at home on this street and the clever design must take the credit.

  • HPH238 : Making Passive House homes affordable – with Adam Cohen

    HPH238 : Making Passive House homes affordable – with Adam Cohen

    Architect Adam Cohen explains how his modular construction system is making Passive House building simple and affordable.

    Interview with Adam Cohen

    Adam Cohen qualified with a Degree in Architecture from the University of Maryland 35 years ago. He was uninspired by the post-modern approach of the time, and instead was a keen follower of Ken Kern and Michael Reynolds‘ owner-built homes, and of Malcolm Wells‘ earthship movement.

    After qualifying as an architect he set about building healthy homes that used no glues or chemicals, were off-grid, had first generation solar panels and composting toilets that they made themselves. Over the several years that followed he found it a struggle to find clients who wanted to build this way so, out of financial necessity, he started a more traditional company that he ran for 20 years, employing 43 staff where they designed what they built, and built what they designed.

    “I had sold out completely”

    The company was very successful financially but it wasn’t until ten years ago when his 12 year old son started asking questions about carbon footprints and climate change that he says he had a ‘slap in the face moment’. It brought home to him that because it had been hard to find people interested in energy efficiency at the time, that he had given up his principles and was building in an entirely different way.

    That realisation gave Adam a renewed focus to “atone for all these sins. I’ve put a lot of potential carbon in the atmosphere by creating crappy buildings.”

    Finding Pasivhaus in 2008, he became one of the first people in the US to take the training. Spending a month in Europe gaining his international certification and spending time with Passivhaus builders, he returned to the US with a desire to build commercial Passivhaus buildings using a design / build methodology.

    “I realised how fragmented and dysfunctional the design and construction world really was.”

    By 2012 others had started sitting up and taking notice of what Adam and his company were doing, and were keen to seek their assistance to help other teams. However his in-house firm of architects, engineers and builders where everyone was working together, wasn’t the way the process worked elsewhere.

    Adam has made it his mission over the last few years, since selling his business, to try and help the industry move forward. He has recently moved to Canada and is helping Passive Buildings Canada put together an education programme to raise awareness that if you’re building new construction it should be done to a carbon neutral standard.

    “They need to reduce their embodied energy and they need to reduce their operational energy and then they need to offset their carbon with either credits, site generation or local generation of energy.

    We have the choice now to be proactive, or we have the choice later to be reactive.”

    The construction industry needs greater awareness of climate change

    Adam believes that in Canada, unlike the US, the federal, provincial and municipal levels are fairly well aligned in terms of being tuned in to the climate change emergency, however within the construction industry there is still not sufficient awareness from the consumers, owners, producers, architects or builders.

    He sees there being far more awareness in the European design and construction community, and the population generally, but sees the greatest potential being what’s going to happen in China in the next 20 years.

    Adam has written a draft paper called “The Integrated Modular Design Theory for High Performance,” which sees a need to move towards building with modular components that can be put together in different ways, manufactured easily and built efficiently.

    The aim is for cost parity

    Once Adam decided to divert his company’s focus to constructing healthy buildings, he realised this was only going to work if he could make an economic argument for it and get cost parity with the alternatives. In the commercial sector this wasn’t too difficult to achieve, but in residential it has taken a lot longer.

    One of the first steps was to convince people to pay more for the construction of the building, instead of a cheaper building with higher energy bills.

    “Then it became a question of, if you’re going to be paying eleven-hundred dollars a month for energy and mortgage and I can deliver a building that’s more comfortable, that uses less energy, and it’s going to cost eleven-hundred dollars a month or less…. if I could take some of that money that you’re spending on those electrons and put them into your mortgage so that you’re building equity and wealth rather than just spending money, but the net monthly cost is the same, why would you not do it?”

    After three years of mining data they were able to put forward a proposition for single-family homes, where mortgage plus energy is equal to or less with a Passivhaus than you would pay for a standard house. Initially that was hard to achieve as windows had to be imported from Europe and there were very few suitable mechanical systems, but now the US market has options available.

    Paying for an experienced team could save money

    Adam tries to encourage owner-builders who are starting out on the process to create a team of people who have experience in Passivhaus, otherwise they might end up wasting money while they learn, to the cost of the client.

    Adam has created a Lego style of system where owner-builders can buy a kit of pieces that snap together making a Passivhaus envelope very simple. Similar systems exist in the UK where you can buy a guaranteed shell and do the rest yourselves.

    Understand the inter-relation between construction stages

    Adam tries to simplify the thought process for self builders when approaching a new project, by helping them to understand the inter-relation between the different stages of the construction.

    He breaks these down into four ‘buckets’. They are:

    • Site acquisition – how much it is going to cost to buy the site
    • Site development – how much it will cost to clear the site, install utilities, do any groundworks and landscaping
    • The construction – the cost of getting the shell up, enclosed and tested for airtightness and thermal continuity
    • The finishes – interior and exterior finishes, including mechanical and electrical and everything else within the shell.

    He explains that when people have a fixed budget, he makes them understand that money can be moved around those buckets as none are fixed. There is an inter-relation between the site acquisition and site development buckets which need to be balanced, before you know how much there is left for the other two buckets.

    Within each area there will be some costs which are fixed but others where savings can be made, such as with the complexity of the design.

    “So, when you start to create your balance of how do I make all these pieces balance in this budget, I want people to understand that you need to separate out your thinking so that you understand, if I go spend a quarter of my budget on the site and then I spend another quarter of my budget on site development, so I have actually half of my budget to build the building with, is that realistic that I can actually get that building built?”

    “Start with, ‘here’s the system, now let’s design to the system’.”

    Using Adam’s Lego style system of modular construction, he explains how clients often use a free programme like Google Sketchup to help with their design. Rather than people coming up with a design and then trying to make it fit a manufactured system, this way allows clients to use the Sketchup modular blocks that Adam has created, to start their design. The manufactured products help generate an efficient form, leading to an affordable solution.

    Consider the long-term impact

    “I would hope that anybody considering a new build would try to work their way through to figure out how to build that building with the lowest impact possible. Because as a species, it’s critical that each of us make the right decision every day in everything we do, and if you’re building a building that’s going to saddle your grandchildren with ongoing operational energy that’s going to be carbon intensive, you’ve kind of just slapped your grandchildren in the face.

    I know that the millions of square feet where I’ve built really bad buildings, I’m now approaching about a million square feet of Passivhaus buildings. So, not that I’m offsetting them, but at least I’m reducing my impact long-term.

    So, I would encourage all of the individuals listening to this to consider their actions when building a new building, and how it will affect their grandchildren.”

  • HPH098 : An Off-Grid, Earth-Sheltered Passivhaus– with Christina Snyder (Passive House)

    HPH098 : An Off-Grid, Earth-Sheltered Passivhaus– with Christina Snyder (Passive House)

    Architect, builder and Passivhaus Consultant, Christina Snyder shares the story of the experimental zero-energy Passivhaus self-build that she and her husband have undertaken in Michigan, and explains why they are in no rush to complete it.

     

    Interview with Christina Snyder

    While this is Christina’s first self-build, she has been involved in projects since childhood when she helped her father to make solar renovations on the family home. In high school she won a design competition for a solar house and, after graduation, began teaching students how to design zero-energy homes. After being beaten in a competition by a team specialising in Passivhaus, she decided to do the training and become a Passivhaus consultant.

    The House is on the ‘Bleeding’ Edge of Technology!

    The project is innovative and experimental in the features that it is bringing together into a single house:

    • It will be both Passivhaus and zero-energy
    • It will be powered with a nickel-iron battery system
    • It will use solar and wind power
    • The surplus energy from the solar hot water system in the summer will be stored to provide domestic hot water and heating through radiant floors in the winter
    • There will be a composting toilet
    • There will be grey water and rainwater storage

    Plans

    4 Years In, and Possibly Another 16 Remaining!

    With so many experimental ideas it is not something they would have wanted to try out on a client house. Christina and her husband however are happy to throw all the ideas together and take their time, possibly even over a couple of decades, to complete the house. They aim to do the project in phases with results being tweaked as they go.

     

    Good Solar Exposure was Fundamental to Finding the Right Plot

    Requiring sunshine from 9am to 3pm all year round in order for their energy needs to be met meant that they used satellite images and solar pathfinders to help locate suitable plots. Benefiting from the economic downturn they were able to source a rural plot from a farmer.

     

    Progress of the Build so Far

    The house has 3 storeys on the south elevation and 2 on the north, one of which is below ground level. Retaining the hole which was 14 feet below ground level on the north, and 3 feet below on the south, was particularly challenging throughout a very wet year.

    The construction below ground level uses 16inch thick structural insulated panels made from EPS beadboard and coated with glass fibre reinforced concrete. This is also the weather barrier, and on the inside acts as the air barrier. They selected this method as it provided the insulation levels required, would give the necessary strength and had less CO2 emissions than insulated concrete forms would have had. Spraying the concrete onto the Styrofoam walls was a gruelling process that needed several hours continuous spraying at a time to ensure the concrete didn’t set in the hose.

    Cleaning up after the first spraying of GFRC over the 12” insulated EPS foam floor with red radiant floor PEX tubing over the continuous structural basement foundation slab.

    Being largely self-taught, this method took a lot of experimentation and they’re still not in a position where they would use it on a client’s house.

    The wooden walls, made of I-joists, have been erected and filled with cellulose insulation, the roof is in place and all but 2 windows have been fitted.
