Berkeley-based practice Terry & Terry Architecture (Ivan Terry, Alexander Terry) has completed 'bal house', a single-storey addition to an existing mid-century ranch house in Menlo Park, California, USA. Conceived for a retired couple, the open and accessible design integrates the living space with the rear garden to create a well-lit domestic extension.
