Triangle, Goswell Road, Finsbury EC1. Designed by Clifford Culpin & Partners for Islington Borough Council. Built 1970–76. The complex comprises three blocks of brown brick and exposed concrete that follow the perimeter of the triangular site, arrayed round a raised central garden court that covers the garages below. The crisp glazing fitted flush to the walls and accented by setback balconies, gives a refined visual and geometric consistency across all three blocks. Access to the inner courtyard is via a series of ramps and steps – as one enters under the monumental bridge that links a large access tower to the upper level walkways, it feels rather like passing through the ramparts into the inner keep of a medieval castle
