During 1967 there was one more sortie into capsule territory, while Peter Cook was working at Hornsey College of Art, Special Design Group. There was a brief moment when the possibility of a prototype existed, and the Hornsey Capsule is more simplified as a form than the earlier capsule. It is basically made from three standard elements which combine to give a one or a two-person unit. It was planned to integrate with larger 'Family Cage' dwellings and the capsule concept seems even now to be a logical approach for pre-family dwellings.
