  1. We've just completed a new build "house for life" - it started as "Passivhaus Principles" as we didn't want to commit to certification during the planning process because of its challenging form, but our Passivhaus consultants (Peter Warm) felt that with a few tweaks it could make it and, as of this week, it has been certified. We also had to go through the "Paragraph 55" (now 79) route to get planning permission, where you have to go to a Design Review Panel of professionals who get to decide if your design is "exceptional architecture". They unanimously approved it while Planning rejected it and also said they didn't want any further discussion on it. However, our forward thinking local councillor took it to the development committee where Planning was over-ruled (a story in itself). To be honest we are not hands-on self-builders in that we used architects, builders, etc to do it and it was an expensive build, but we were in a position to do this because what we actually hands-on self-built was a successful software company that was then sold. We were very involved in the whole process, living 250 metres from site, and especially in selecting and pushing the eco kit and we also had a planning condition to put a photographic record of the build in the public domain, which being a keen photographer I have done: www.thewalledgardendevon.uk Eileen designed the landscape and is now implementing it with muscle from local ex-marines. So it's a certified Passivhaus with private water supply, a positive energy house through solar and using both electrical and thermal batteries, with an EER of 101. We started a bit late on Buildhub as we were having problems with our Sunamp thermal batteries and we got a lot of help from @JSHarris in particular and others. However, happy to answer questions about our experiences if that's useful.....
  2. Hi guys, Just joined this group. Just finished building a Passivhaus in Penzance, Cornwall. My friend and I built 2 houses together, one for each family on a challenging plot chasing the passivhaus dream... We've been in the house since end July and just seeing how it copes with our first winter! So it's a timber. Frame design, sitting on a concrete raft (on 30cm insulation!) planned using the PHPP software to conform to PH standards. So it's super insulated, airtight (0.3ac/hr) no cold bridges, triple and quadruple (skylights) glazed with Brink MVHR system (ubbink plastic duct and plenum). My friend developed the wall buildup himself to achieve the PH standards without us having to buy premade PH timber frame sections, saved us a lot of money... Biggest struggle so far, trying to get the. Brink post heater to operate... It's wired up correctly but won't operate, even at high fan speeds...? Which is really why I joined this forum, to hopefully glean some info as our supplier hasn't solved it (or Brink at this stage!) Cheers.. Murray
  3. The Passivhaus Trust has announced that the number of certified Passivhaus units in the UK has topped 1000 - with at least as many again in the pipeline. http://www.passivhaustrust.org.uk/news/detail/?nId=787
  4. I know this has been discussed at some point, but it was on a very tiny slope and I have found nothing about anyone trying near a Watercourse or similar. So my question is: Is it possible under any circumstances to build Passive Slab on a slope of ca. 1.5 meters next to a Watercourse. My guess is "No" But i still think it s worth a try, as this would be a good slab solution. Here is some measurements (see Pic below) . House will be on a slope of 1.5 meters over 21 meters distance. But the bigger problem probably is the Watercourse directly next to it - oh, and I forgot- a few trees as well. I will ask Structural Engineer the same question, but her solution so far is not really a cheap one (Pile and Beam with slab , first quote coming is : 47000£+VAT 🤪 😳) Thinking by now that it might be best to leave concrete out and just put suspended Timber Floor on Screwpiles. Anyone in here got experience with this? Even Though Helical Piles are not cheap, might still end up much cheaper. Has anyboday ever tried installing helical Piles themselves ? I just had a quote for the Piles themselves - just material - 1600mm length excl. shipping for 15USD each (100/pallet) , seems cheap enough to me 🤫
  5. Hello everyone, I came across this great Forum through JSHarris Blog (which was quite an amazing read to me). The first time ever that I found really usefull information in bulk, as a lot of the Info about so called "self building" is really just customised building (I tell the architect what i want and how it should look like at the end and then just empty a wheelbarrow of cash in front of his office every week) . My approach to building my own home is a little different, as I am German and as far back as I can remember I never heard about anyone buying an off-the-shelve home ( whats the point of someone else building YOUR house ) . That s until I moved to the UK, where it is the other way round (why would anyone go through the stress of building their own home if you can buy it off the shelf) . I hope I can learn bits and pieces here and also ask a few questions, as a few of you seem to be quite experienced and knowledgeable. It is always good to have advice from people who have done similar projects as there is a chance of avoiding costly mistakes here. So here I am , bought myself a plot of Land (came across it by accident, driving through the countryside in Wiltshire) with an old Timber Shed on it.(Shed is not quite the right word, as its footprint is around 130sqm) Wanted to renovate the Timber buidling (It s an old Assembley Hall ) and planned everything until I discovered that the foundations are too poor. So now I will have to knock the old down and build new. Which is an advantage somehow as I dont need to stick to any restrictions from the shape of the old building , but unfortunatley this will cost a fair bit more money (apparently Foundations are really expensive 😄 🤔 ) . The House going to be a 1 1/2 Storey Bungalow-Type 3 Bedroom with approx. 160sqm which we will try to build as energy efficient as possible on our tight budget.(We meaning Wife and Kids , although not planning to use the Kids as Labourers just yet 😛. It will be Timber frame, but unlike so many of you, I do not have the option to use a Kit (or SIPs ) , as there is no access for a Lorry, Crane or even a Van within 50-60 meters from the site. So it will have to be built on site (oldschool) . I am now looking into the details of how to get construction Plans together (not really Building regs, as this is not that difficult to figure out) for the actual building to start. Most guys here that have done a House themselves have used a Timber Frame KIT and where provided with Construction Plans by the company or, alternatively had these done by their architect. The Problem with Architects is(as discussed elsewhere) , that they are quite expensive and on top of that rely on others to work with them (Structural Engineer) to make the plans work. Quite a bit of information for an introduction post so i stop here and just leave it with some drawings and models of the House .
  6. I've just come across this article in the local rag. Only two of these houses currently, but it's a good start. Turn on your adblockers, by the way, as the local news will take a long time to load up by the time it's done all adverts. Bournemouth Echo council passivhaus article
  7. Hi all, about to embark on self-build project. We have plot and planning. The layout optimises solar gain so I am keen to achieve passive house standard. I have noticed on this forum that many self-builders seem to include UFH in their passive house build but I have been told this is simply not necessary... So i'd be grateful for thoughts on this please!
  8. Hi, My name is Ted Nicholls, I'm a third year undergraduate studying Building Surveying at the University of Westminster. Please find attached a link to my dissertation questionnaire- 'An assessment of self-build homes in the UK in the context of the EU’s directive for nearly zero energy buildings (nZEB) plan for 2020. Through various questionnaires and interviews I hope to promote it as a feasible way to achieve nearly zero energy buildings' It would be really appreciated if anyone could take part in it and also forward the survey onto any individuals or companies with self-build knowledge to help further my research. Thanks in advance and best regards, Ted Nicholls https://goo.gl/forms/iBffpVYYSUjPsHu82
  9. Is there anyone out there who is in the early stages of their build 'journey', ideally a Passivhaus? The podcast/website www.houseplanninghelp.com, which I have been listening to since it started and think is very useful, is looking for its second self build case study for its Hub. It has already been following the build of Long Barrow, being built by Alex Baines, near Cirencester. This is an ICF, earth sheltered Passivhaus and now they are looking for a second case study to follow through from planning to final build. If at all interested, contact Ben Adam Smith at the website. Similar to myself, he has been researching as much as he can while looking for land for his own build but, like myself, not finding anything affordable. However, as well as learning himself, he has been sharing everything he has found with others via his podcasts and now the Hub. It would be great if someone could help him out with another case study. He wants it to be useful for everyone, including you, your builders and build team and will hopefully include all the good points as well as all the bad parts. After all, thats often when we learn the most. Hope someone can help. I'd love to do it but no luck with the land yet. www.houseplanninghelp.com
  10. Hi everyone, I'm a "mature" retired electronic/electrical design engineer come computer networking consultant come PH self builder. See following link for existing building details. http://passivhausprojekte.de/#k_4186 Currently designing second PH for construction in Brinkworth, on Woodbridge park golf course. Build commences 2nd August. Also designing next door neighbours from PHPP perspective. Scandanavian Lodge design ( planning requirement), Isoquick insulated raft foundation, Beco ICF walls (polstyrene lego bricks according to my wife!), attic trussed warm roof. Approx. 240m2 and 550m3 gross including voids which are within thermal and airtight envelope. Techie bit. Hmm.. The intension was to have very similar to current house as it works well! However no mains gas so all electric. MVHR to be a Paul Novus 300 with Lindab rigid safe ducting, silencers etc. Thermal store to be Akva Nero 750l (current house has Akvaterm std tank of 500l with top and bottom DHW coils giving up to 35l per min). Change of size result of no mains gas and probable use of Eco7 electric to supplement Solar PV via Immersun PWM switch to two high temp immersions. Space heating via VEAB CCW 125-6-2.5 in living area duct branch only - no active heating to bedrooms. Summer active cooling via VEAB CWK 125-6-2.5 in bedroom ducting only or VEAB CWK 160-6-2.5 for all areas... 3kW ASHP air to water supplying the VEAB CWK. Secondary DHW loop to provide "instant" hot water to all areas with little potted water wastage (as per current house). Well that was the plan until I discovered Sunamp and Zehnder Comfocool Q600! So undecided now although no apparent pricing/availability of Sunamp Stack.... Sunamp PV 5kW units look good but only a fraction of the capacity of a 750l TS. Multiple units look very expensive by comparison. However, need to make a decision soon I guess.......
