What stands out
- In 13 of 16 cities a square metre of a small apartment costs more than one of a large apartment.
- The biggest premium is in Wroclaw (+39.8%).
- Small units are popular with buy-to-let investors, and the fixed value of the location is spread over fewer square metres.
Methodology
- Apartment sales from the Polish Real Estate Price Register (RCN, published by GUGiK; free since 13 February 2026): market sales of full ownership only, implausible prices removed.
- 12-month window ending at the newest deed published in each city – counties publish with different delays.
- Weekly open data for all cities (CSV, CC BY 4.0) is on GitHub: poland-housing-prices.
