3-room floor plans: compact and flexible

At least 10 m², better 12: then it works in any role – as an office with two workspaces, as a children's room across all ages, or as a guest room with a real bed instead of a sofa bed. Smaller rooms under 9 m² formally meet the room definition, but noticeably restrict later use and reduce the resale value.

Yes, precisely because of demographic change: small, low-barrier houses are equally in demand from couples, single people and seniors – a growing target group. A single-level 3-room bungalow of around 85 m² is one of the most broadly marketable house formats of all. Key for retaining value are a timeless layout and threshold-free execution.

Depending on size and construction method, EUR 190,000 to 260,000 turnkey (as of 2026, excluding land). Tiny-house variants with three small rooms start below that, generous 3-room bungalows of 100 m² lie above. Since the bathroom and kitchen occur in full, the square-metre price is higher than for large houses – but in absolute figures the format remains the affordable entry.
