Church Street resolves a fractured grain by exploring ideas of a site within a site and a building within a building. Two villas – each composed of a group of interlocking volumes wrapped in a robust brick envelope – face each other across a communal courtyard on this deep but narrow plot. The pattern of openings punctuates the blocks and imposes a golden-section-derived sense of order over the complex geometries of overlapping forms. Developed for One Housing Group, this new build project accommodates 55 tenure-blind homes for families, couples and single people on the site of a disused shirt factory in London’s east.
