O'Sullivan Skoufoglou Transforms 1930s London House into Low-Carbon Home and Studio

O'Sullivan Skoufoglou Architects has converted a 1930s property in Canonbury, London, into a combined family residence and working studio, prioritizing spatial restraint and low-carbon retrofitting. The practice rejected outward expansion, instead preserving the original layout and proportions while making precise structural punctures for cross-ventilation and daylight. The material palette features muted earth tones, warm timber, unvarnished plywood, and reclaimed terracotta. Custom joinery follows Arts and Crafts principles, with freestanding units matching existing 1930s door and picture rail datum lines. A dead attic space was reclaimed as a master bedroom and office, accessed via a new timber staircase and lit by a recessed dormer window. The roof assembly uses wood-wool insulation and a vapor-permeable membrane, leaving original rafters exposed. Construction waste was repurposed: bricks from a dismantled chimney breast became garden paving, old pine floorboards were re-machined into fencing, and terracotta roof tiles were laid as a patio. The design includes provisions for a SunAmp thermal energy store and future solar panels. The project demonstrates that contemporary living and professional work can be retrofitted into historic envelopes without destroying character, positioning low-carbon retrofit as a frontier in sustainable urbanism.
