    HPH184 : Balancing a self build with work and family life – with Donal O’Leary

    Donal O’Leary tells us about his self-build in Ireland and shares advice for a successful project.

    Interview with Donal O’Leary

    We catch up with Donal O’Leary, the first House Planning Help Hub member to complete a self-build project! The decision to self-build came about by accident, as Donal and his wife were originally looking for a run-down property to renovate or rebuild. The properties they viewed didn’t quite meet their needs or budget, and suddenly the right site came along.

    An unorthodox approach helped them secure their plot

    Donal explains, “We didn’t really need the full site as it was. It was actually too big and therefore it was outside of our price range.” After making enquiries and seeking legal advice, they came to an agreement with a neighbouring landowner to join forces and put in a high enough offer to outbid another interested party. The site would then be split into two, for their own developments.

    It took a year of planning before construction started

    After acquiring and sorting out the site, the second year was the planning phase, split into obtaining formal planning permission and working with architects and quantity surveyors.

    In Ireland, you have a pre-planning meeting with the local authority. This is an opportunity to run through plans and get approval to apply for formal planning permission (or find out what needs to be done differently). Donal explains you don’t have to have final drawings, but you do need to provide plans showing where the house will sit, access, and services like sewage and water.

    Cost dictated the final design of the house

    The site was large enough to accommodate a big house. But for Donal and family, the priority was a comfortable, clean and healthy home that would take advantage of the light and aspect, as well as modern insulation and air-tightness standards. Cost ultimately decided the final design, and the overall size was dictated by that design and how the spaces were arranged.

    The budget was based on some funds left over from the sale of their previous property, plus the mortgage amount they would be able to secure. Donal adds, “The rainy-day fund and the piggy bank were all broken at this stage. So, we worked out roughly what we could afford…and worked back from that primarily.”

    The planning phase included very detailed specifications

    Their architect and quantity surveyor filled in most of the tender document template, detailing the build specifications. Donal and his wife provided additional information (such as doorknobs, stove handles, bathroom finishes) to complete the document.

    It took five or six iterations of 20-30 page documents to figure out exactly what was needed. Donal says in hindsight it was definitely worth it, but at the time it was difficult. “You’re at the stage where you can’t even visualise what the house looks like, and you’re expected to say, ‘well, I want a Belfast sink with a tap that goes a certain way’.”

    Time-wise, their biggest challenge was appointing a builder

    Christmas time was the deadline for receiving responses to their tender. Donal says, “I’m sure the builders were delighted to be filling out a huge tender document on Christmas Eve!” They narrowed it down from four builders to two, met both and then picked one. Availability was a very important factor, as well as previous experience and price. The tender process took a couple of months and the actual build lasted just over 12 months from start to finish.

    A precise calculation helped them stick to their budget

    The quantity surveyor broke the build down to a very detailed level, so they knew exactly how much it would cost. Donal says they were reasonable estimates with a bit of wriggle room to alter the spec if needed, when it came to actually buying fixtures and fittings.

    There were only a few minor changes during the build stage. Donal attributes this to the time spent upfront with their architect and quantity surveyor on the spec. It gave them a baseline to go back to, which helped them manage their finances. And they had monthly budget reviews with the builder.

    They tried to attend site as often as possible

    The building contractor was effectively the project manager. So for Donal, the biggest challenge was not a technical one, it was just keeping on top of everything and being available. He admits it’s difficult when you have to take calls and send emails while at work, but says you just have to find a way.

    Donal advises others to take any chance they get – before or after work, or at lunchtime if you’re nearby – to go to site and give an opinion so things can move on. His wife spent any spare time during the day onsite, involved in the daily decision-making. Donal recalls a few times where just being there averted a disaster, explaining, “So, if we weren’t there, they would’ve done x, but because we were there, they did y.”

    Keeping their architect engaged in the entire build process was worthwhile

    Laws have changed in Ireland and you have to have an Assigned Certifier; an engineer or architect signs off the various certification and documentation across each phase of the build and can be held accountable by the local authority.

    Donal and his wife chose to involve their architect (who they found through word of mouth) for the whole project. So she had a vested interest not just from a design perspective, but also legally and financially. As the client, they had the reassurance of a professional overseeing the builder.

    They leaned on their architect quite a lot. As Donal explains, “It’s not just somebody who draws nice designs, prints them off and you go, ‘move a wall here, move a wall there.’ It’s far more than that. It’s a design eye, it’s finishing, it’s the construction knowledge that the average client doesn’t have.” She was a good sounding board when they had to make decisions, offering suggestions and steering them in the right direction.

    Sustainability had to be balanced with budget

    There were times where a sustainable option wasn’t the most economical or expedient, for example they considered rainwater harvesting but the cost involved would have pushed the build over budget.

    However, they tried to reduce the carbon footprint of their new build where possible:

    • Orienting the house for solar gain, with canopy-style shading to reduce overheating.
    • Avoiding the need for oil due to high-spec insulation.
    • Using an air source heat pump.
    • Leaving some of the garden as a nature area for wildlife, planting some clover there instead of grass so as to have a low maintenance meadow.

    How stupid is our obsession with lawns?

    If you’re planning a vast lawn for your new house, is it actually the most sustainable thing to do?

    Donal recommends listening to a Freakonomics episode which ponders how natural lawns are and looks at alternatives.

  • HPH180 : Where to live during your house build – with Ben Adam-Smith

    HPH180 : Where to live during your house build – with Ben Adam-Smith

    Ben Adam-Smith runs through the main options of where to live while your new home is under construction. While there’s potential to save a lot of money it should not impact significantly on your comfort, state of mind or key relationships.

     

    Money spent on temporary accommodation is not necessarily wasted

    A lot of this depends on your personal situation.

    With sufficient funds the decision becomes so much simpler, but if your self build is only going to happen with you living in a caravan on site then make sure you’re not romanticising what this will be like.

     

    Consider who is involved and how they might be effected

    Here are a few questions that might be useful to run through:

    Who will this impact?

    If it’s just you then you are likely to have a realistic sense of which route is right for you. With a family, there’s a lot more to balance . . . and a lot more at stake!

     

    What are your needs?

    Whenever you buy (or rent) a house the location, price and availability are at the heart of the decision.

    Consider proximity to work, schools and all importantly your building site.

    What is your mental attitude like?

    If you’re someone who needs luxuries and space just to survive then sleeping in a campervan may be easy to rule out. However, even if you go camping every weekend would living this way for a year be viable?

     

    How long will you be living in temporary accommodation?

    Even with the best intentions projects can overrun. So envisage yourself living in your chosen accommodation for double or triple the time you have in your head!

    And do you still feel good about it when it’s cold, raining, and it’s been a bad day on site?

     

    1. Stay where you currently live

    With the funds available, by far the easiest option is to stay put in your existing property. This minimises disruption with just one move (from current house to completed self build). It’s also likely that this is a comfortable environment.

    Other than the cost implications, the only other down side is if your existing property is a long way from your plot.

    If you anticipate being on site every day then this reason alone may be cause to move.

    2. Move into a rental property

    Although this is likely to involve you moving twice – once from your existing home and then again into your new build home – it shouldn’t be too disruptive once you’re settled and in a level of comfort that suits your needs.

    You’ll also have the ability to get closer to your land.

    The downside here is that money is going out on a monthly basis and if your project is significantly delayed this will soon add up.

    It also might not feel as homely because the landlord may not be open to excessive personalisation (painting walls, adapting spaces, etc.).

     

    Don’t overspend on the rental property

    The cost of rental properties will vary hugely. It’s worth visiting a number of properties to get a grip on the market and what is good value for money.

    If you are selling your existing home, also be aware that you may not have much time to make this decision. We found that the choice of houses available in our price range was far more limited than we expected.

    3. Move in with family or friends

    Potentially this option could save you a lot of money. However, it really comes down to how strong that relationship is with the person you intend to impose upon.

    If the house is large enough then maybe there is room to have your own space. Even then, perhaps there will still be an element of being on your best behaviour!

     

    Other things to consider is the distance to your plot and the fact that if things do go wrong you are probably in danger of damaging a valuable relationship.

     

    4. Erect temporary accommodation on your site

    We’ve all seen it on Grand Designs . . . the family that thought it would be a good idea to stay in a beaten up caravan on their plot for the duration of the build! Hmmm.

    Well staying on your site doesn’t have to be primitive: you have a few options.

    There are considerable savings to be made by doing this but one other benefit is that you can keep an eye on the site as work progresses. This is of course a double-edged sword! You won’t have a retreat away from site and will have to endure the noise.

     

    If you have young kids it is entirely possible that they may have an accident somewhere. Yes, the site will be fenced off but kids have an uncanny ability of gravitating towards things/areas they shouldn’t!

     

    An outbuilding

    Where your project has permission to construct an outbuilding, such as an office or garage block, if it offers enough space this may be a good option for staying on site. You’ll also be confident with the specification of the building (during the depths of winter!).

     

    A caravan or static home

    Living this way does not mean it has to be damp and dingy. They come in all sizes and to all levels of comfort.

    The question is really whether to rent or buy.

    Buying could be cheaper . . . but only if you are confident you can sell it on afterwards.

     

    A mobile home or campervan

    Slightly different to the last option but again offering varying levels of comfort.

     

    Don’t forget about storage

    If you are building a new house then hopefully it’s got all the space you need.

    If your existing home is fairly modest too then just watch out for ‘downsizing’ during your project!

    Hopefully you’ll see it coming but it’s amazing how much stuff you can actually have.

    And even with the best intentions of sorting through what you need, you may discover – like I did – that time flies by and then you just have to pack up to clear the house.

     

    Secure storage units are usually easy to find, but they aren’t always cheap. So factor this in if you haven’t got storage space in your temporary accommodation.

     

    When should you move?

    In some respects you want to leave this to the last minute! Nobody wants to compromise their living environment until they have to. In reality it is a balance though. You don’t want the stress of needing to pay bills and not have the cash flow.

    As you won’t be paying for services upfront your money will go out gradually during the build.

    Just remember that selling your home may take longer than you think. For Mike Coe it took about a year!

    HPH114 : The long road to high performance homes – with David Olivier from Energy Advisory Associates

    David Olivier from Energy Advisory Associates shares some of his personal and professional experience of creating energy-efficient homes.

    Interview with David Olivier

    David Olivier has 35 years of experience in supporting UK architects and engineers on leading energy-conscious building designs. He was involved in environmental research early in his career before starting his own freelance business advising people on energy and environmental improvements. In 2012 he moved into his own passive solar energy self build home in Herefordshire.

    National policy emphasis should be on investment in domestic energy conservation

    When David left education in the mid 1970s he went to work for an environmental research body linked to Friends of the Earth, called Earth Resources Research. While there he worked with three colleagues on a study of the long term energy needs of the UK and the potential for meeting them with renewable energy combined with better energy efficiency.

    Published in 1983, the report concluded that by 2025, if the political will was there, the UK could provide around two thirds of its energy from renewables. It also concluded that the UK could improve its energy efficiency by about threefold over 50 years, with the result that it could reduce its energy consumption and increase the standard of living of most people.

    Back in the ’70s the concern was more about the price of oil and heating bills rather than CO2 emissions. Even today, there is still the concern about energy prices. David suggests that despite inaction and lack of interest from governments, there has been an improvement in energy efficiency over time in the UK. The use of energy efficient lightbulbs for example has seen a marked effect on electricity consumption.

    David would like to see a shift in policy away from national investment in nuclear energy and fracking, and instead see that money invested in energy conservation in the domestic sector, such as subsidising the cost of buying highly energy efficient domestic appliances.

     

    Aim for a higher standard than UK building regulations

    David suggests that if you’re looking to self build you should ignore the standards set by UK building regulations and aim to exceed them. He explains that the standards set in other European countries are far superior to our own, with Sweden for example having higher building standards in the 1980s than we have today. He recommends applying more insulation and thinking about the Passivhaus standard which will give you a more comfortable, draught-free environment.

     

    Don’t upset the planners!

    When it comes to securing a building plot David’s advice is, if you have the option, consider a move to parts of East Anglia, Scotland or Wales, where they are more readily available. In case of uncertainty and to avoid overpaying for it, he would recommend you have a chartered surveyor give a valuation.

    David suggests looking at the council planning policies for the areas in which you are searching for a plot. His search area incorporated 6 different councils, with 6 very different planning policies ranging from relaxed and positive to completely draconian! He had a 6 month long battle to reverse the decision of a junior planning officer on what really should have been a minor point. If in any doubt about this stage, he recommends first consulting a planning expert before liaising with council officers. Another suggestion is to quote to officials parts of the Self-Build and Custom Housebuilding Act 2015, which is an act that puts a legal duty on the local authority to make efforts to help self-builders obtain serviced plots.

     

    Future-proof your house design

    Always consider that if you’re planning to self build you could be living in the finished house for 10-20 years or more, and over that time you’re going to want to make heating it affordable, no matter what the future holds. Even if you’re building in a town David recommends orientating the house towards the sun.

    “Even at the present day energy prices you can justify doing a lot more than the UK building regulations require you to do when you insulate a new house.”

     

    Use passive solar energy long before considering solar PVs

    David moved into his house in 2012 but still has some areas that need finishing. The house is 105m2, two storey and detached. The windows are approximately 70% south facing and their area is equivalent to around 30% of the floor area. By comparison, he says a developer house would be closer to 10-15%. The large windows provide more all year round solar gain, though it is important to incorporate methods to avoid excess summer solar gains. Even before external shading and curtains have been fitted the temperature of David’s house has not exceeded 24.5°. When this shading has been installed it is likely that it will be 2-3 degrees cooler in summer heatwaves.

    The house is of concrete construction, with concrete floors and concrete block partition walls, which has the effect that the summer temperatures are not as extreme as they would be in a lightweight construction house.

    “I was keen to go down the thermal mass route because it’s a way of making fuller utilisation of passive solar energy, which is almost free if you are building a new house….Passive solar is something which everybody should be using long before they consider using solar water heating or solar photovoltaics.”

     

    Getting things built and materials supplied to the standard specified was the greatest challenge

    David was surprised that failures in materials on his build were greater than failures in workmanship. Particularly he felt let down by the suppliers of three insulation materials, which didn’t meet the specification and which caused problems as a result.

    Despite being on site at least once every day he wasn’t able to avert particularly inept tradesmen from messing up laying the stone floor tiles.

    The living room stone floor was ground down by 1mm and the surface repolished  after the tradesmen left. This picture is after the remedial works were carried out.

    The granite kitchen floor was left uneven by the tradesmen. Being too hard to grind down, it has had to be left unchanged.

    David says that friends and colleagues of his from Europe who spend time watching building sites operating in the UK, come to the same conclusion as him – that things just don’t operate smoothly.

    “They should operate better than that and systems ought to be put in place that mean that they can operate better than that which would make life much easier for self-builders, because self-builders don’t always have a construction background and therefore they need to rely sometimes on building tradesmen doing things right. And my experience showed that in one or two cases building tradesmen didn’t know how to do it right and I was aware that they were making mistakes, but the average self-builder might not be aware.”

    Property company fined for false advertising

    The Bournemouth Echo reports on a case where a property developer has been fined after falsely claiming that their properties at Pennsylvania Heights, Portland, were built to certified Passivhaus standard.

    This has got Ben Adam-Smith thinking for the following reasons:

    1. Even though they failed to reach the standard, they still wanted the prestige associated with it
    2. Isn’t it good that you can really define what a Passivhaus is
    3. Doesn’t this all mean that in the future there will be added value if you can prove that you have a certified Passivhaus?

    You can read the article here.

     

    Regen Media opportunities

    At Regen Media we’re always seeing new opportunities arise and are looking for more great people to help with various different projects. Perhaps you’re someone who works in construction, you’re a Passivhaus architect, builder etc. with a passion for teaching. Or perhaps you’re the reverse and are a teacher in education that’s wanting to do something around climate change, around building better homes. Or maybe even you work in TV, radio or write for a newspaper but this is where your passion really lies. If this is sounding like you, then we’d love you to get in touch!

     

    The Hub update

    There is so much that can be learned from visiting building sites, and The Hub is all about making that on-site experience available to a wider audience. We’ve been fortunate enough at The Hub to follow the Long Barrow Passivhaus project and our latest video takes us up to the raft foundation stage.
    Each month we’re adding a new module too. In January we were looking at self build loans, how they work, cashflow, making sure you don’t overspend etc.
    We also have a community element, with a Facebook group for Hub members to share advice, tips and answer questions.
