This extension to an existing terraced residential property in the Muswell Hill area of London squeezes a generous amount of new living space within the confined constraints of the existing footprint. Rather than converting the existing loft space, opportunity was discovered to create a whole new en-suite bedroom through the complete removal of the existing roof and formation of a whole new volume at high level. With a generous ceiling height, tall glazing, hidden lighting and high-spec internal finishes the new bedroom, en-suite bathroom and walk-in dressing room creates a serene contemporary space with extensive views from the rear.
