Germany, Essen, 2000
To satisfy the family's needs in modern living standards an annex to the early 50s house was designed.
The new structure is placed next to the gable wall with a glazed gap in-between.
By connecting the pre-existing sanitary piping to the new building the whole house now can make use of solar heat produced by solar collectors on the new roof.
Two storey high glulam frameworks make the main supporting structure that is horizontally stiffened by Kerto-panels. Vertically insulated wood frame elements do the job. The facade consists of mahogany plywood panels and structural glazing elements with stainless steel tilting wings.
