Plastic House II

Plastic House II is situated west of Gothenburg, on the Swedish west coast with a great ocean view. The clients for this 200 square meter house are the same as for the Plastic House I the Swedish, Gothenburg based Unit Architecture AB designed ten years ago.

The architects explain: For us, two things were fundamental during the design process of Plastic house II. First, to maximize the fantastic view, and second, to minimize the impact on nature. We could basically remove the house, and the only thing left would be the 19 holes drilled in the mountain for the pillars. To reduce the footprint further the drains have been placed above ground and covered with a layer of earth. We strove to keep the design simple and at the same time retain a luxurious feeling as in the Case Study Houses built in the fifties in California. A kind of glamour camping. A simplicity and comprehensibility in the built structure, but with generous living qualities. At the same time, we tried to build in dissonances both in the material palette and the actual geometric composition, to avoid too much of a classic modernism.

The floor plan is simple,- private areas facing east, and the public area, with direct access to the adjacent granite rocks, facing west. The division between the two parts lies at the center of the house, along the longitudinal axis. The public area with kitchen and living room can be separated from the kid’s living area by a sliding door. The house is supported by 19 circular 80 mm columns. Each column is placed in a drilled hole (300 mm deep) and have then been fixed with an expanding plaster. The locations and the heights of the columns have been measured in on-site to enable prefabrication before the galvanization process. The columns support three HEA 200 beams that together carry the whole house. All steelwork is galvanized and powder-coated in white.

The complete steel construction was carried out in two weeks. On top of the steel a prefabricated wooden frame was mounted in less than three weeks. The underside of the house has been covered with white perforated corrugated aluminum. Due to the exposed position, all other metal work is also done with coated aluminum. The windows have been built with Schücho´s system. The facade is a development of the system we created for Plastic house I, a façade with 5 mm of opak PMMA is taped with velcro acrylic foam tape mounted on standing sheet metal studs to avoid exposed fixings and to handle the thermal expansion. Photo: Per Nadén.
