Glen Cottages is a two-storey extension project we completed last year near Bristol - transforming an old stone cottage. Read all about it and see more photos here
The sedum roof is now on at Woodlands Eco Home in Gloucestershire and looks fantastic -great work from all the team and Poole Single Ply Roofing Systems!
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.
We recently joined forces with The Green Register to offer a site visit at our current Passivhaus build on an Urban Infill site in Nailsea, near Bristol. They have put together a short video of the afternoon - click below for a taster of the event and a very chilly Richard and Malcolm talking about our commitment to sustainable building and the benefits of partnering with The Green Register for site visits like these.
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!
The preliminary air test was carried out on our Nailsea Passive House project on Friday 9th February, achieving the excellent result of 0.27ACH.
The house is due for Passivhaus certification once completed but at the moment we are at first fix stage - air tight and weathertight - hence the preliminary test.
The result required for Passive compliance is 0.6 ACH @ 50 Pascals and the figure achieved was 0.27 ACH (lower is better).
This is a great result and as ever testament to the hard work and attention to detail shown by our guys on site - well done!
Richard Hatfield and Malcolm McMahon were interviewed by Richard Brown of The Property Voice recently for his regular podcast. He described Greenheart as being 'on the ground pioneering sustainable building in the real world' which we can't argue with!

Lots going on at our Passivhaus build in Nailsea currently - underfloor heating going in, MVHR installed in the loft, with boards to hold in extra insulation. This home will be seriously snug and warm for its owners come next winter!
Join us a for talk and tour of our latest new build passivhaus project in Nailsea - a three-bedroomed house on an urban infill site.
We have joined forces with The Green Register for this special event on February 22nd. Richard Hatfield will start by talking about our involvement in the project followed by Piers Sadler talking specifically about the attention to detail required for passivhaus certification.
Greenheart director Malcolm McMahon will then give an overview of the project, a tour around the house and site followed by a Q&A session.
Place are very limited so visit The Green Register website for more information and to book.
We have set to work on the refurbishment and extension of a tired 1950's two-storey house in Backwell, near Bristol, designed in collaboration with s2 design.
A large two-storey, open plan Timber frame extension will have lots of glass to the rear of the building to make the most of the views over the Severn estuary, with WARMCEL insulation and high spec triple glazed windows keeping it snug.
The existing house will be fully refurbished with new windows, improved levels of insulation and new interior layout.
The Timber Frame is in place and we continue to make good progress at the Passive House in Nailsea, Somerset.
The carpentry team are in and the Timber Frame is going up at our Passive House project in Nailsea
Work continues at Rose Cottage in Kingsdown, Bristol...
We have started work on a new single-storey house in France Lynch, Gloucestershire, designed to blend into the hillside.
The house will be dug into the bank with a sedum roof, and walls clad in timber and local stone. It will be very highly insulated - aiming for an airtightness result of less than 1 ac/h - with an MVHR system and triple glazed windows.
We collaborated with Millar+howard workshop for the planning designs, with detailed design and build by the Greenheart team.
Foundations and retaining wall are now underway with the timber frame due to start in December.
We completed Rose House in Kingsdown, Bristol, a few years back, working in partnership with Emmett Russell to build a highly insulated, timber-framed new build family home, with excellent airtightness results.
Now some of the Greenheart team are back to begin the next phase on this plot...
Having stripped the original building down to four walls, the guys are preparing a weather-tight shell for a new two-bedroom cottage which will take its place. Built to similar sustainable building principles as Rose House, the cottage will be airtight and well insulated with high performance windows.
The half tonne RSJ is now in place...
Are you a skilled and experienced carpenter? We've got a busy period ahead and could use an extra pair of hands to join our friendly team. Please contact us if you're cheerful, skilled and hardworking, and would like to help us continue our high standards in sustainable building.
We have just started work on a new three bedroom Passive House in Nailsea, designed in collaboration with S2 Design and Piers Sadler Consulting.
The clients wanted a future proofed house, so a full-roof integrated PV system alongside battery storage and air-source heat pump will be installed.
The bespoke timber framed house will be built to Passivhaus standards and certified, with completion due June 2018.
