Woodstock Apartments, a new block of flats in North Oxford, is a paradigm for the radical yet sensitive densification of sustainable suburbs. It sits comfortably among its neighbours by respecting the parameters of the built context: building line, ridge line, eaves line, materials. But just as the local houses are clearly of their time – Gothic, Arts&Crafts, Georgian – so is this building unabashedly contemporary, with its cantilevered cuboids, the dramatic cleft marking the entrance, and the shimmering bronze cladding to its upper floors. But this building is not just about form-making. It acts as a benchmark for a radical programme of Contextual Densification. The plot previously accommodated a single family house with a high carbon footprint. By contrast the new building contains 7 apartments with a possible occupancy of over 24 residents, increasing the number of residents by 5 times.
