An extension to fill the void between the existing house and garden wall to become a new light-filled bedroom, ensuite and lobby area, all with enhanced levels of insulation and draught-proofing.
The clients request was to create a ground floor room which could accommodate a sofa bed and desk, to act as a home office and guest room. A shower room and rear-lobby were also requested. The client was also keen to make improvements to the energy loss of the property where possible.
The simple garden wall creates privacy on the corner site, and this has been retained and lengthened to create a modest amount of additional accommodation. Contemporary vertical cedar boarding lifts the elevation to an aluminium cap to provide the required internal space.
The bedroom faces the street with a tall slot window and rooflight, while the shower room is an enlargement of the WC below the stairs to create a space-efficient ‘Jack and Jill’ shower room. The rear lobby has high level windows, glazed French doors and a rooflight to provide lots of natural light, while maintaining high levels of insulation throughout.
A warm flat-roof area with sedum above gives high-performing flat-roof insulation, and can accommodate future PV panel installations.
High-performance air tightness tapes and sealants were used throughout.

“We have had so many appreciative comments from neighbours, visitors and passersby. The extension is in stylish counterpoint to our traditional 1930s semi, both complementing and enhancing its look and we are very pleased with it”

“Matt listened carefully to our brief for a light-filled, well insulated extension serving a variety of functions.
He came up with some different designs, and was always responsive to our concerns and needs as we made our choice.
He also managed the building process efficiently and professionally and was a reassuring presence throughout the design and build process”
