Living area
Prefabricated houses from 120 to 150 m2
The range from 120 to 150 m2 is considered the classic family size: enough room for children and a home office, without needlessly inflating the area. These six houses hit exactly this layout.
The living area between 120 and 150 m2 is seen by many as the ideal family size - large enough for children's rooms, a study and an open living area, yet still manageable on building and running costs. In this selection six houses between 123 and 150 m2 are available, mostly two-storey detached houses with four to five rooms.
These include the E 20-148.6 by SchwoererHaus (137 m2), the Neunkhausen by Fingerhut Haus (133 m2), the grant-eligible Natalie 2 by Dammann-Haus (135 m2) and the Belando by Buedenbender (150 m2), as well as two saving-oriented alternatives: the TwinStyle 15.01 S shell duplex by massa haus (136 m2) and the Double 10 semi-detached unit by allkauf haus (123 m2). The starting prices with a fixed value range from 156,999 EUR to 445,985 EUR; two houses are calculated per project.

Why 120 to 150 m2 is the family sweet spot
In this area range the typical family needs can be met well: an open living-dining-kitchen area on the ground floor, three usable rooms on the upper floor and often an additional room for the home office. The Neunkhausen by Fingerhut Haus, for example, fits a study onto 133 m2 that also works as a guest room. At the same time the area stays small enough to keep building and heating costs within bounds.
The range therefore combines the best of both worlds: more comfort than houses up to 120 m2, but without the higher costs and larger plot requirement of the over-150 m2 class. For most families with one or two children this layout is enough in the long term, without rooms standing empty and unused.
From the KfW efficiency house to the duplex built by your own labour
The six houses show the full range of concepts in this size. The Natalie 2 by Dammann-Haus is a KfW Efficiency House 40 EE and available turnkey for 358,600 EUR - of interest to anyone focused on grant eligibility. The E 20-148.6 by SchwoererHaus relies on an energy-saving heating system without conventional radiators thanks to its fresh-air heating with heat recovery.
Anyone wanting to save also finds a way here: the TwinStyle 15.01 S by massa haus delivers 136 m2 as a shell house for under 160,000 EUR, provided you handle the interior fit-out yourself. The Double 10 by allkauf haus (123 m2) is likewise available as a shell house. This way the family size covers both turnkey and own-labour-oriented building families.
