Fissure House is a minimal home located in London, United Kingdom, designed by Threefold Architects. Space was optimized by creating a single linear staircase occupying a triple height void or ‘fissure’ along the edge of the building. Internally, variety and excitement was achieved between floors by cutting back each floor plate to create dramatic views and glimpses of different living spaces. The character and materiality of existing brickwork was celebrated and complimented with new bespoke joinery and metalwork, embracing the strong craft tradition within the local area. New openings and external terraces were introduced at the rear transforming a once crowded and claustrophobic site into a spacious, light and multi-layered home.
