How much does a 70 m² prefabricated house cost? [2025]
“I want to build a small house, but how much does it really cost?”
This is one of the most common questions investors ask—and one of the most confusing. Online, you can find offers starting at PLN 1,700/m²... but upon closer inspection, it turns out they're shells, with no windows, roof, or interior.
In this article, I show the real costs of a 70 m² prefabricated house – broken down by technology, standard and heating impact.

✍️ Expert commentary – Dorota Burzec, Domki Marysia
"If someone offers you a 70 m² house for less than PLN 300,000 turnkey , ask what's actually inside. Often, it turns out there's a missing bathroom, no heating system, or unfinished walls. At Domki Marysia, we present our quotes transparently – broken down by technology and stage."
❓ Frequently asked questions (FAQ)
Is it possible to build a 70 m² house for PLN 200,000?
It's possible – in a shell state, with a very simple design and a cheap foundation. But not turnkey.
Will a 70 m² house fit under the “on notification” law?
Yes – but only if you meet the conditions: 1 house on the plot, up to 70 m² of development, single-family housing, no services, compliance with development conditions or local zoning plan.
What about VAT?
If you're buying as an individual, you'll pay 8% VAT for the full service (materials + assembly). If you're buying just the prefab, you'll pay 23%.
