Developers will be subject to a calculation determining the extent of their mandatory contribution to infrastructure developments. “It will be either a financial contribution directly linked to the implementation of public facilities in the area, or a non-financial undertaking such as creating green spaces such as parks or planting trees in streets, creating schools or kindergartens, necessary transport infrastructure, or the transfer of housing construction to city ownership,” said Filip Foglar, an architect who coordinated work on the new rules.
