- Rosswald-Saflisch, CH
- Trigon Holiday House, designed by Heidi und Peter Wenger
- A small house almost perfectly integrated into the landscape but impressive by its individual solutions for the openings. One side is completely closed by a triangular shutter. When lowered down it is creating a balcony. The glazing has also triangular shapes.
- The three lower part windows can be opend in a turning wing manner. The fact was that related to the extension of the lowered down shutter-balcony a kind of pre-zone is created whereby a sunken floor table situation can be created without generating any feeling of falling out.
