new large side extension over two storeys offering special and new views from it and through from the houses into highgate woods to the north. It is on the party boundary of the land so the glass is one hour fire resisting and so is the woodwork. We stacked modules of superbly made (Lignum Joinery) framing trying to create Mackintosh like end elevations that look onto our clients front and back gardens. The interior is remodelled to enjoy some small double height space in side extension, and extended theatrically centre into garden as contemporary conservatory in similarly glazed modular format, with half as sliding glass exterior.
