PSSHAK (Primary Supports Structure Housing Action Kit) being erected at Adelaide Road, Camden, London

NOTES: The PSSHAK was a system of prefabrication devised by Nick Wilkinson and Nabeel Hamdi, based on the writings of the Dutch architect Nicholas Habraken and designed for mass housing. Two schemes were built using this method by the GLC, at Adelaide Road, Camden, shown here, and at Stamford Hill, Hackney.
