02 Feb Planning approval win!
First Passivhaus planning application to be approved in the Forest of Dean
Treetops Passivhaus is a replacement dwelling for a pebble-dashed cottage in dire need of modernisation. The client looked at Enerphit and a large extension, but for a number of factors it was deemed easier to rebuild.
Treetops is a fantastic example of what is possible with timber framed construction, with a number of external materials providing juxtaposition between the differing elements.
A reconstituted stone rain-screen to the front façade and rendered block gables emulate the traditional vernacular and appear as the original cottage.
The dwelling consists of three separate elements, the stone-clad section where the original cottage stood, the rendered block front façade to the East suggesting a side extension, and a contemporary rear ‘extension’ complete with timber cladding to the roof and walls.
The timber clad rear section shall feature British Cedar, felled locally and cut by the client.
Unusually for a Passivhaus, the dwelling features a large number of North facing windows due to planning constraints requiring the fenestration to remain identical on this elevation, along with maintaining the same eave and ridge heights.
The Rear timber clad element of the house shares the same form as the front of the house, albeit slightly lower to give a subservient appearance, joined to the front of the house with a joining section. The joining section is planned with charred timber (shou sugi ban) to avoid blending in with the timber cladding that will be left to silver naturally.
Adams:Scott provided design service and Passivhaus consultancy on the project, and will continue to provide close assistance to the self-build client as the project progresses.
A blog of the build shall follow.

“The client struggles to keep their current house heated to 17̊°C and regularly observes bedroom CO2 concentrations of over 3,000PPM during the winter. They can’t wait to complete their self-build so they can experience the true comfort of Passivhaus!” – Scott Adams
