These two houses are characterised by
their green facades and roofs, which merge
with the landscape, and by their ecologically
appropriate concept. The notable feature
of the layout is that the rooms are disposed
around a central multi-purpose hall with a
gallery above, thereby avoiding corridors
and integrating a winter garden. All interior
walls display timber frame and exposed
loam surfaces. The timber roofs show
special domical designs made from timber
logs. Shelves and even the sink in the bath-
room were built from unbaked loam (see
chapter 14).150 Built examples
