150 m² modular house: layout and cost guide
A 150 m² modular house can be planned as a stacked or L-shaped combination of several modules. A plausible editorial room programme is five to six rooms. This page helps you structure the first comparison before requesting manufacturer-specific plans and quotations.
| Planning item | Editorial reference |
|---|---|
| Turnkey house body | €285,000–€480,000 |
| Module concept | a stacked or L-shaped combination of several modules |
| Room programme | five to six rooms |
| Typical planning profile | families wanting an additional study, guest room or multipurpose room |
Budget orientation
At 150 m², multiplying the editorial rate of €1,900–€3,200 per m² gives an indicative house-body range of €285,000–€480,000. This is a calculation example, not a quoted total project price. Obtain separate figures for foundations, connections, surveys, permits, transport, crane work and external areas.
Layout and everyday use
For five to six rooms, separate the quiet and active zones early. Check circulation space, storage, furniture dimensions and whether bathrooms and kitchens can share compact service routes. For accessible planning, allow sufficient movement areas and step-free thresholds before the module dimensions are fixed.

Frequently asked questions
How much can a 150 m² modular house cost?
The editorial house-body calculation is €285,000–€480,000, based on €1,900–€3,200 per m². It excludes several site and ancillary costs and is not an offer.
How many modules are plausible?
A useful first planning assumption is a stacked or L-shaped combination of several modules. The actual number and dimensions depend on the manufacturer's system, transport and structural design.
How many rooms fit into 150 m²?
five to six rooms is a plausible editorial orientation. Storage, accessibility and circulation may be more valuable than adding another small room.
Does the range include the plot and foundations?
No. Plot, foundations, groundworks, utility connections and external works should be calculated separately unless a written quotation explicitly includes them.
Is planning permission required in Germany?
A residential modular house is generally subject to the same planning and building rules as another permanent residential building. Confirm the specific plot and project with the responsible authority.
