How much money do you need to build a 100 m² house? – Marysia Houses Guide

100 m² house – the most common choice of Poles

Today, 100 m² is the sweet spot: sufficient for a 2+2 family, functional, and yet still financially manageable. But how much will it realistically cost to build such a house in 2025?

It depends – on the technology, the standard, and the approach. Here's a guide that will show you the real range.

🛠️ Construction technologies: prefabricated or traditional?

Technology Lead time Cost of developer state Turnkey cost
Prefabricated 3–4 months 400–480 thousand PLN 500–600 thousand PLN
Traditional (brick) 10–14 months 430–530 thousand PLN 550–700 thousand PLN

Prefabrication offers advantages in terms of time, fixed cost, and energy efficiency. Traditional construction may offer greater flexibility, but it carries greater cost risks.

💸 Cost estimate for a 100 m² prefabricated house (turnkey option)

Element Price range
Design + documentation 8,000 – 12,000 PLN
Production and prefabrication 300,000 – 360,000 PLN
Transport and assembly 30,000 – 40,000 PLN
Foundation and installations 50,000 – 70,000 PLN
Interior finishing 80,000 – 120,000 PLN
TOGETHER ~500,000 – 600,000 PLN

The price may include: heat recovery, heat pump, smart systems, photovoltaic panels – depending on the package.

⚠️ What else needs to be added?

  • Plot and utility costs (if you don't have them)

  • Administrative and surveying fees

  • Connections to the network

  • Fence, terrace, driveway

  • Buffer for unexpected expenses (min. 10%)

Is PLN 500,000 enough?

👉 Yes – but under certain conditions:

  • You already have a plot of land

  • You are building a prefabricated house in an economic standard

  • You decide on a limited footprint and reasonable finishing

If you want a higher-class house, with a garden and extras, it's worth spending 550,000-650,000 PLN.

Summary

Building a 100 m² house in 2025 is possible from as little as PLN 500,000 , especially using prefabricated technology. It's a fast, predictable, and energy-efficient way to build your own home.
