Floor plans around 120 m²: the family standard

120 m² is considered the standard for the family home: two children's rooms, a study and a second bathroom find space without overstretching the plot and budget.

Kurzantwort

What fits into a 120 m² floor plan?

The classic layout: below, a 45 to 50 m² open living-dining-cooking area, a guest toilet and a utility room; above, the master bedroom, two children's rooms, a family bathroom and a small study. Alternatively, the bungalow spreads the same 5 rooms across one level but needs more land for it. Turnkey, the 120 m² class sits at about EUR 270,000 to 350,000 in 2026.

Floor Plans around 120 m²: häufige Fragen

Kompakte Antworten für die erste Planungsphase.

5 rooms on 120 m² – can it be done without feeling cramped?
Yes, if circulation areas are minimised: a compact hall with a single-flight staircase, room doors leading directly off a small distributor and doing without long corridors save 8 to 12 m² that benefit the living rooms. Children's rooms of 11 to 13 m² and a master room of 14 m² are then realistic without the living area falling below 40 m².
Second bathroom or larger children's rooms?
At 120 m², usually only one of the two fits. Families with young children benefit more from larger rooms that grow with them over the years. The second full bathroom pays off from two teenagers, or if the parents want their own shower bathroom – as a space-saving solution, a 4 m² shower bathroom off the master room often suffices instead of a second family bathroom.
How much does a 120 m² house cost?
In 2026, budget EUR 270,000 to 350,000 turnkey – depending on construction method, roof shape and energy standard. The city villa with two full storeys lies at the upper end, the classic gable-roof house at the lower one. Land and ancillary construction costs come on top. As a shell-completion house with DIY work, entry drops to around EUR 200,000.
