Now used as the campus Refectory, the Prototype House was completed in 1986 and was the first building to be realised at Hooke Park under the stewardship of John Makepeace and the Parnham Trust, who owned the woodland before the AA. Designed by Ahrends, Burton and Koralek (ABK), Frei Otto and Buro Happold, it was initially designed as accommodation for the School for New Woodland Industries that Makepeace established at Hooke Park in the 1980s. The building is supported by a series of four Corsican pine roundwood A-frames, holding up a ridge cable from which slim roundwood rafters made from Norway spruce thinnings are hung.
