New rules shift the balance of power

The bank points out that new spatial planning rules are influencing the land market. Analysts assess that after the reform not every plot will retain its value. Land with a settled designated use gains, while plots without such status may lose appeal (Ceny gruntów znów w górę. Nie każda działka zachowa wartość – portalsamorzadowy.pl).

What's next

Analysts expect prices may continue to rise in the coming quarters, although the pace depends on how quickly municipalities adopt local zoning plans. People planning to buy a plot should check the designated use of the area in the local plan before signing a contract.
