Our Passivhaus project in Nailsea, near Bristol, has been certified a Passive House Plus by WARM / Passive House Institue, with fabulous airtightness results (see certificate, below). Well done to all involved! Keep an eye on our project page for photos and full project details, coming soon.
Great to see our Pitchcombe Gardens deep retrofit project featured in Bristol 24/7 magazine recently, with kind words from client Ian Mawditt of Four Walls: “We had a good experience with Greenheart – they took on board exactly what we needed and put our requirements ahead of their own timetable. Quality was important to them all the way through.”
Also fabulous to learn that the clients have slashed their gas bills by 90%!

It's all kicking off in Colerne! Groundworks have begun on a three-bedroom, timber-clad home in rural Wiltshire, that will be built to Passive House standard.
This is a Greenheart In-House Design & Build project, implementing the Passive House Planning Package. The house will be timber-framed and WARMCEL insulated and - we hope! - complete by next summer.
It was an exciting day for clients Terry and Frank at our Passive House project in Nailsea this week, as they met with Richard Simon, Director of Solarsense and energy consultant Piers Sadler to hand over the renewables package prior to commissioning and learn how the various elements of the system work, using the latest technology.
The package includes a whole roof integrated 7.3KW PV system, a Mitsubishi air source heat pump with thermal store and the latest TESLA battery – Powerwall 2 - for storage.
Once registered with TESLA all the data can be monitored via an App on a smartphone, laptop or tablet.
The house, which achieved preliminary air test results of 0.27ACH back in February is almost complete and ready to be signed off as a certified Passivhaus - the first in the wider Bristol area.
We have started work on Hill House, a timber-framed, WARMCEL-insulated family home which will boast four bedrooms, three bathrooms and far-reaching views across Bath and the surrounding countryside.
Our experienced team have already started the complex groundworks - which involve ground retaining walls and underpinning existing structures - on the steep, tight site, which is the clients' current garden. The clients can look forward to moving into their new Passivhaus-standard home in around twelve months time, enjoying spacious open-plan living with bedrooms downstairs and living quarters upstairs, to maximise enjoyment of the views down the valley.
The house will have a car-charging port, Thin Film PV Panels applied to the metal standing Seam roof and an air source heat pump providing heating and hot water. The finishes will be Larch, Breathable Render and Cotswold Stone.
Lots of hard work ahead on this exciting eco home that has been thoughtfully designed by CaSA Architects and Greenheart.
See above for how it WILL look... and below for how it looks at this early stage!
Glen Cottages is a two-storey extension project we completed last year just outside 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
