134 m² two-storey 3+1 with a bedroom on the ground floor

This two-storey prefab house has a 3+1 layout – three bedrooms plus a living room – on 134 m², with two bathrooms. Its most useful feature is the split of the bedrooms: one on the ground floor, two upstairs. That makes the plan well suited to multi-generation living, where a grandparent sleeps downstairs without using the stairs, or to families who regularly host guests.

Ground floor: a 32 m² living room and independent guest quarters

The ground floor combines a 32 m² living room, a 14 m² kitchen, a 16 m² bedroom and a 5 m² bathroom. The downstairs bedroom and bathroom together form a small independent unit: an older relative, a visiting family member or a guest has everything on one level. The 32 m² living room comfortably holds seating and a large dining table, while the 14 m² kitchen can take a breakfast table of its own.

Upper floor: space for parents and children

• A 22 m² bedroom, the largest room upstairs, with space for a double bed, a wall of wardrobes and a seating or work corner
• A second 16 m² bedroom, large enough for two children to share
• A 6 m² bathroom and a 5 m² hall

With a bathroom on each floor, nobody has to go up or down at night.
