Floor plans from 200 m²: room for big plans

From 200 m², the floor plan can do more than just house you: a granny flat, a dual home office or a dedicated children's area with a play hallway – this size allows real functional zones instead of single rooms.

Kurzantwort

Who needs 200 m² and more?

Three groups typically plan this big: families with three or more children, multigenerational households with an integrated granny flat, and builders who combine living and working under one roof. It makes sense to structure the space into clearly separated areas with their own access. Turnkey, 200 m² houses start in 2026 at about EUR 460,000; with upmarket fittings, EUR 600,000 is quickly reached.

Floor Plans from 200 m²: häufige Fragen

Kompakte Antworten für die erste Planungsphase.

How do you prevent 200 m² from feeling impersonal?
Through zoning rather than expanse: successful large floor plans divide the area into perceptible zones – the two-storey hall as the centrepiece, a fireplace room as a retreat, the children's area with its own play hallway. Different ceiling heights, floor coverings and sightlines provide orientation. A single 80 m² great room, by contrast, quickly feels echoing and is hard to heat and furnish.
Plan in a granny flat right away?
At this size, almost always sensible: a self-contained 50 m² unit on the ground or lower floor costs only moderately more to build, but opens up options – rental income, an au pair, caring relatives, or later your own single-level living in old age. As a second dwelling unit, it can also raise the KfW funding ceiling. Separating it later is significantly more expensive than planning it in.
What running costs does 200 m² cause?
More area means permanently more energy, taxes and maintenance: even in an efficiency house, 200 m² incurs about 60 to 80 percent higher heating and electricity costs than 120 m², plus higher property tax, insurance and reserves. A photovoltaic system with storage and renting out the granny flat cushion this – but plan the items in from the start regardless.
