  Our Church Rd project coming together in Combe Down. Among other changes, we designed-out a few tons of high energy steel, leaving an entirely timber framed structure.
Now nearing completion its looking great. Credit to HRA architects for the concept design, Henry for the technical design and George and the Greenheart team for all the hard graft. Watch this space for updates as we continue to ice the eco-cake!

After years of intending to join the ranks at the National Self-build and Renovation Centre, we have finally found the time to rustle up a stand (one day soon we might even finish it!). So if you're ever on the M4 at Swindon and fancy a visit, come and find us - we're at the back near our pals at the Green Building Store.  Thanks to all who attended our site visit in Colerne last week. We enjoyed the opportunity to discuss this near-Passivhaus project with attendees and answer some interesting questions. Feedback was positive and everyone seemed to enjoy the opportunity to tour the building, which is at structural/first fix stage. Huge thanks to Piers Sadler, The Green Register for co-organising this event and of course the clients! 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.   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!  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!  Underfloor Heating going down at Nailsea Passivhaus project  MVHR installation in loft at Nailsea Passivhaus, with boards to hold in extra insulation  MVHR at Nailsea Passivhaus  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.  Passivhaus under construction by sustainable builders Greenheart  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.  |
