On 15th March we'll be collaborating again with The Green Register opening up our site at Eastrip Lane, Colerne for a Futureproof site visit and talk about this contemporary three-bedroomed timber frame house built to Passivhaus standards.
The topics discussed in this tour and talk - materials used, MVHR, airtightness and methods of construction - are just as relevant to retrofit as new build projects.
The building is timber frame constructed on site from 360mm timber I-beams and wrapped in 100mm Pavatex woodfibre boards. The external faces will be either render or geometric cement sheet panels, whilst the roof is anthracite corrugated cement sheet. Windows are from Internorm (Passivhaus certified). All walls and roof will be insulated with Warmcel 500 Cellulose insulation.
The building is still under construction and so during the visit, it will be possible to see all aspects of the building fabric: air tightness layers, MVHR ducting, timber frame and Pavatex wood fibre.
Places are limited. Visit The Green Register website for full details and to book online.
Work continues at Hill House in Bath. All the groundworks are now complete, which were always to be the biggest challenge in getting the house built. We needed to provide level access from the road on to the site which was 3m lower. To add to complications the site is sloping steeply and was also close to the adjacent Georgian house. We have used a combination of retaining structures, underpinning and strip foundations to tame the site!
The carpenters are now on site to get the frame going - a 360mm thick engineered timber wall for exceptional U-values and breathability, with a continuous airtight membrane to the inside of the frame to guarantee air quality, efficient heating, and a comfortable living environment for the clients.

The scaffolding is coming down and Second Fix at our Passivhaus project in Nailsea is well underway. Oak architrave and skirting boards are being fitted and the beginnings of the kitchen on this timber framed newbuild near Bristol that achieved a preliminary air test result of 0.27ach in February.
It's all go on site at our current newbuild in France Lynch, Gloucestershire at the moment!
Firstly, a visit from Darren Evans Assessments delivered an impressive air test result of 0.64ACH yesterday. This highly insulated, single-storey timber frame home has never been intended for Passivhaus certification (which requires 0.6ACH or lower) but we are very happy with this result nonetheless!
It's all systems go too with our guys installing WARMCEL insulation and preparing the roof for sedum - more photos to come.
Work continues at our single-storey newbuild in France Lynch. The airtight membrane is nearing completion and the triple glazed windows are now in (more photos to follow). The single ply roof is in place (thanks Poole SIngle Ply) with sedum yet to come.
Scroll for photos and original drawings for what will be a super insulated, low impact home in a wonderful spot in Gloucestershire.
We joined forces with The Green Register last week to offer a site visit to our current Passive House project in Nailsea, near Bristol.
Twenty construction professionals braved the cold to visit the Station Rd project, which isn't yet Passivhaus-certified but has already achieved an outstanding preliminary air test result of 0.27ACH. Attendees had the opportunity to look around the site, ask questions and listen to presentations from Greenheart's Richard Hatfield and Passivhaus consultant Piers Sadler.
“Richard and I were really pleased with the event - those attending seemed to find it interesting and useful to visit a Passive House project which is still under construction. This gave everyone the ability to see in “real life” how and why the house was put together” said Greenheart Director Malcolm McMahon.
We hope to run many more site visits in partnership with The Green Register in the future - watch this space!
