140 m² of living space: generous, yet economical
Short answer: A prefabricated house with around 140 m² offers room for five to six rooms — including a study, guest room or second bathroom. Currently you will find 24 houses with us between 132 and 150 m², the cheapest from €328,080 catalogue starting price. The manufacturer prices apply "ex works" for the respective construction stage; the plot and incidental construction costs come on top.
The jump from 120 to 140 m² sounds small, but it noticeably changes living: the compromise "study or guest room" becomes an "and". The home office gets a fixed room, visitors get their own room, and a second bathroom eases the morning of a family of four. At the same time the size remains affordable — anyone who really uses the additional rooms gets the best out of every square metre.
What 140 m² additionally makes possible compared to a 120 m² house
| Extra compared to 120 m² | What becomes possible | When it is worthwhile |
|---|---|---|
| Separate study | Home office separate from the living area | Working from home permanently |
| Guest/multi-purpose room | Guest room, hobby or music room | Regular visitors, changing use |
| Second bathroom / large master bathroom | Easing daily family life | Larger family, high comfort expectations |
| Two full storeys (city villa) | Full ceiling height without roof slopes | Prestigious look, clear massing |

City villa with two full storeys: the showpiece form of 140 m²
Around 140 m² is made for the city villa: two genuine full storeys with full ceiling height, crowned by a shallow hipped or pyramid roof. The advantage over a house with a converted attic of the same floor area is obvious — no disruptive roof slopes, every square metre is fully usable, and the rooms feel generous and bright. The clear massing also gives the house a prestigious look.
Anyone who prefers something more classic will of course also find 140 m² as a detached house with a gable roof — the floor area then spreads more onto the attic. Both routes are good options; an overview of the building forms is provided by our page on the city villa as well as the detached house.

Checklist: when 140 m² really pays off
More floor area means more possibilities — but also more costs. These points help with the decision:
- First clarify what the additional floor area compared to 120 m² is intended for — home office, guest room, second bathroom?
- A study on the ground floor separates work and living; plan for daylight, soundproofing and a network connection.
- Consider city villa vs. gable-roof house: two full storeys provide full ceiling height without roof slopes.
- A second bathroom or master bathroom eases daily family life — sensibly bundle the pipe routes from the factory.
- Let storage grow along: a dressing room, storerooms and a utility room (HWR) prevent living rooms from being repurposed.
- More floor area means higher heating and maintenance costs — counteract this with a heat pump and PV.
- Consider the catalogue 'from' price and total costs separately: calculate the plot and incidental construction costs separately.
