100 m² of living space: what fits into a compact prefab house
Short answer: A prefab house of around 100 m² offers space for three to four rooms — ideal for couples and small families. With us you'll currently find 41 houses between 90 and 110 m², the cheapest from a catalogue starting price of €289,000. Important: these manufacturer prices apply "ex works" for the respective completion stage and include neither the plot nor additional construction costs.
Building compactly does not mean sacrificing living quality — it means using floor space deliberately. An open living-dining-kitchen area feels more generous on 100 m² than a string of small rooms. Less floor space also means: lower construction, heating and maintenance costs over the entire service life. That is precisely why this size is so popular with couples, singles with a home office and young families.
Floor plan variants for a compact house of around 100 m²: advantages and pitfalls
| Floor plan variant | Advantages | To consider |
|---|---|---|
| Bungalow (one level) | Low-barrier, short distances, no stairwell needed | Needs more plot area, often a higher per-m² price |
| Compact two-storey | Economical with the plot, usually cheaper per m² | Staircase needed, circulation areas cost living space |
| 1.5-storey / knee wall | A good compromise, sloping ceilings usable | Usable area under the slopes is limited |
| Compact L-shaped bungalow | Separates the living and sleeping areas, sheltered courtyard | More external wall area, more demanding to plan |

Cost per square metre: why compact houses seem relatively more expensive
Anyone who compares the pure per-m² price is sometimes surprised: small houses often cost more per square metre than large ones. The reason is purely arithmetical — expensive areas such as the kitchen, bathroom, building services, foundation slab and roof arise with every house and are spread over less floor space at 100 m². The price per square metre is therefore only a rough guide value; more meaningful is what is contained in the respective completion stage and which additional construction costs come on top.
In our current selection, the catalogue "from" prices range from €289,000 to €329,000 — the range is mainly explained by the completion stage (fit-out-ready to turnkey), fittings and energy standard. Always add the plot, site development, building permit and outdoor works to the house price — the guide to house construction costs shows how.

Checklist: planning a compact house cleverly
On a small floor space, every square metre determines the living comfort. These points help make the most of 100 m²:
- Set the room programme honestly: how many bedrooms do you need today — and in five years?
- An open living-dining-kitchen area instead of many small rooms makes 100 m² feel considerably more generous.
- Plan storage space: a utility room, storeroom and built-in wardrobes save valuable space in a compact house.
- Minimise hallways — every saved circulation area becomes usable living space.
- Decide between a bungalow and a two-storey house based on the plot layout and the site occupancy index (GRZ) in the development plan.
- Check the extension reserve: a convertible attic or a later extension in case the family grows.
- Never confuse the catalogue 'from' price with the total costs — calculate the plot and additional construction costs separately.
Too small or too large? Other living areas compared
Does 100 m² feel too cramped for your family? Then plan a size larger with a prefab house with 120 m² — the family standard — or go straight for a prefab house with 140 m² with room for a home office and guests. Anyone searching by budget will find what they need among the prefabricated houses by budget. For single-level living, it's worth a look at the bungalow.
