82 m² two-storey 2+1: daytime below, bedrooms above

This two-storey prefab house arranges a 2+1 layout – two bedrooms plus a living room – over 82 m². The split is clear: the ground floor is for daily life and guests, the upper floor for sleeping. That suits a couple or a small family who like a quiet, separate sleeping level, and owners of a narrower plot who want the house to take up less ground than a single-storey building of similar size.

The 82 m² plan floor by floor

• Ground floor: 15 m² living room, 10 m² kitchen and a 3 m² WC
• Upper floor: bedrooms of 15 m² and 10 m², a 5 m² bathroom and a small 1.6 m² landing
• Staircase: 6.7 m² of the plan

The WC on the ground floor means guests never need to go upstairs, while the full bathroom sits right next to the bedrooms. A 10 m² kitchen has room for a small breakfast table, which takes pressure off the 15 m² living room. The larger bedroom takes a double bed and wardrobe comfortably; the 10 m² room works as a child's room, guest room or study.

Points to weigh up for the 82 m² model

Everyone who sleeps here uses the stairs every day. If older relatives will stay for long periods, consider whether that is practical for them. Details named for this model:

• Betopan exterior cladding for a modern, weather-resistant façade
• Lead-free ERPEN PVC windows and a Pakpen PVC balcony door
• Concealed electrical and plumbing installations
• American-style panel interior doors
• Painted galvanised steel roof, metal tiles as an option

Plan socket, lighting and plumbing points on both floors before production, since the wiring and pipes run inside the walls.
