Created as a modern home with traditional farmhouse influences, the House MW is topped with a simple black corrugated iron roof and embraces the outdoors with a shaded terrace measuring 592 square feet. The timber facades and gables were constructed through off-site prefabrication in a carpenter’s workshop and were later transported by truck to the site. Locally sourced spruce boards clad the facade.

“The ‘skeleton of the house was made of concrete (raft foundation, slab and staircase),” explains Ralph Germann architectes. “After the concrete masonry part was completed, the prefabricated wooden facades were attached against this interior concrete structure. By using this method we could build a house for a reasonable cost, with low ecological impact and at the same time we were able to reduce the construction time.”

The interior of the home, which is nearly 2,500 square feet, is bright, airy and lined with birch plywood panels. Concrete partitions finished with plaster, painted with RAL 9010 mineral paint, round out the interior siding. The ground floor ceiling and staircase are made from unfinished concrete. All furniture designed by the architects was constructed from birch venee,r save for the solid larch indoor and outdoor dining tables. An air / water heat pump and photovoltaic solar panels power the home.
