Planning win for Forest of Dean Passivhaus
Treetops Passivhaus is a detached replacement dwelling for a pebble-dashed cottage in dire need of modernisation. The client initially explored the option of retrofitting to EnerPHit alongside a large extension, but for several factors, it was deemed easier to rebuild.
The self-build project will predominantly be carried out by the client, IJJ carpentry, & PHT member Adams:Scott. This will be the first Passivhaus project for both.
A reconstituted stone rain-screen to the front façade and rendered block gables emulate the traditional vernacular and appear as the original cottage.

The proposed 172m2 timber frame dwelling consists of three separate elements:
-
A stone-clad section where the original cottage stood.
-
A rendered block front façade to the East suggesting a side extension
-
A contemporary rear ‘extension’ complete with timber cladding to the roof and walls, featuring 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.

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!

Planning permission was granted January 2017, with construction due to start later this year. Keep your eyes peeled for a blog of the self-build. The clients hope to occupy the newly completed home in Winter 2018.
