Most people searching "SIP turnkey house cost" already know they want a single supplier for the whole process — from design through to handover. Here's a breakdown of real prices by house size.
Quick answer
A SIP turnkey house realistically costs from ~€1,030/m² for simpler projects. Smaller houses (Tiny House) tend to have a higher price per m², since fixed costs (bathroom, kitchen, utilities) are spread over a smaller floor area.
Prices by house size
| House type | Living area | Turnkey price | Price per m² | Build time |
|---|---|---|---|---|
| Tiny House | 24.78 m² | €28,900 (excl. VAT) | ~€1,167/m² | ~2 months |
| Single-storey family house | 63.65 m² | €65,557 (excl. VAT) | ~€1,030/m² | 30 days production + 14 days assembly |
| Modern two-storey family house | 140 m² | from €154,000 (excl. VAT) | ~€1,100/m² | Full turnkey build |

What's included in a "turnkey" price
- Project documentation and manufacturing of SIP panels (EGGER OSB, Austrotherm EPS 70 Grey)
- Full assembly on your building plot
- Building envelope — roof, windows, doors
- A single supplier, a single contract, for the entire process
What else affects the price
- Floor plan shape (a simple rectangular layout is always cheaper than a complex one)
- Number and size of windows and doors
- Number of storeys
- Site accessibility for assembly equipment
Why a SIP turnkey house is faster and more predictable
Unlike masonry construction, where price and timeline can shift during the build, SIP panels are pre-manufactured in a factory to exact specifications. This makes the agreed budget and schedule easier to control, subject to the final design, site conditions and contracted scope.
