A self-build project for one of the partners in the practice, the magnificently named Cranks Castle is a house on top of a sea wall with fantastic views. Since the government’s Draft Shoreline Management Plan makes the future of the building uncertain, the new owner had to abandon plans for replacement and extend the dilapidated original. She rearranged spaces within the existing footprint, for instance adding a generous hall for sandy clothes. A local carpenter made the windows, and those on the seaward side have external shutters to protect them from flying pebbles in winter storms. All windows make the most of views.
