This house was built on top of the remains of a German bunker. It would have been more expensive to demolish a concrete block measuring 11 by 26 metres and 5 metres tall than to use it as an artificial bedrock and underlay. There are two entrances to two garages. As it was impossible to penetrate the 2.5 metre thick roof slab, service runs lead through existing openings and all stairs are external. The oblong residence has terraces stepping down to the garden. All components extending beyond the bunker have their own concrete structures to support them. Crude hand-moulded brick, slate and rubble stone complete the picture.
