Basement construction: prices by source
Five sources with varying levels of reliability, deliberately kept separate so that declarations are not mixed with evidence. The price index consists of cited public price lists per unit of service (PLN/m²); customer reviews show amounts for entire jobs submitted via the ‘How much did you pay?’ form, with three verification levels (how we verify them); company price lists contain prices entered by the companies themselves. Price index as at: 29 September 2026; customer and company entries are updated continuously.

Options and additional fees
| Option | Price | Sources |
|---|---|---|
| typical basement beneath a house, total price (60-100 m²) | 150,000 ‑ 280,000 PLN | muratordom.pl, jakbudowac.pl |
What affects the price
- basement area
- stage of completion: open shell, closed shell or with utilities installed
- location (e.g. Poznań as an example of a more expensive market)
- construction technology and type of soil
- finishing and installations charged additionally (stairs, insulation)
Usually included in the price
- foundation walls and basement ceiling in shell condition
- waterproofing
Usually charged separately
- interior finishing
- stairs
- installations (priced separately, approx. PLN 500-800/m²)
the price depends heavily on the level of finish: an unfinished basement is clearly cheaper than a fully finished one with installations.
Prices from customers and companies
Two types of entries: customers state how much they paid for the entire job and rate the contractor; service providers enter their price lists. Customer entries have three reliability levels: ✓ verified: invoice or receipt (the editorial team has seen a document matching the entry), ✓ verified: declaration (the author confirmed the entry using a link sent by e-mail) and unverified (how we verify entries); we do not verify company price lists. Price lists entered by companies are not included in the median at the top of the page; customer amounts are included only for services priced as a complete service.
