Timber frame SIP construction
Recycled wood fibre insulation
Reclaimed bricks (from within 50 miles)
Reused steelwork (smaller sections only)
Raised timber floor (in lieu of concrete)
Green roof
Issues: lintel and window reveal were designed as Portland stone but were changes to concrete due to supply chain problems.
We have made other design choices that have resulted in a reduction in carbon use too, such as designing a ground floor in timber frame rather than the typical concrete and adding a green roof to increase bio diversity.
As part of the works we are improving the energy performance of the original house, adding insulation beneath existing floors and upgrading the performance of the existing glazing.
The project is an example of how to transform a home whilst treading lightly on the earth. The project extends and renovates the ground floor with a stepped extension and extends the roof space with a dormer. The design references the Edwardian details of the local area with an arched projecting window and textured brickwork to the ground floor extension.
It is built in timber frame and reclaimed Suffolk white brick which is sourced within 50 miles of the site. It also uses wood fibre insulation which has net positive embodied carbon.
