142 m² 4+1: one bedroom on the ground floor

4+1 means four bedrooms plus a living room. The special feature of this two-storey prefab house is where those bedrooms are: one sits on the ground floor, the other three upstairs.

• Ground floor: 20.7 m² living room, 11.5 m² kitchen, 11.4 m² hall, a 13 m² bedroom, a 3.9 m² bathroom and a 2.5 m² WC.
• Upper floor: bedrooms of 16, 15 and 12 m², a 6 m² bathroom, a 10 m² hall and a 3.7 m² corridor.

Who benefits from the 142 m² model's ground-floor room

A bedroom with a bathroom nearby on the entry level is valuable for multi-generation households: a grandparent can live without climbing stairs every day, while the parents and children sleep upstairs. The same room can serve as a guest room, so visitors have their own bathroom and do not need to go upstairs, or as a home office close to the entrance. Upstairs, the 16 m² and 15 m² rooms suit parents or teenagers, and the 12 m² room a younger child. The 10 m² upper hall adds breathing space between the rooms. With two bathrooms, one on each floor, morning routines are split naturally between the levels. When planning, check how the ground-floor bedroom relates to the living room, since noise and privacy will matter to whoever sleeps there.
