In Poland, most provisions of the amendment simplifying the building process took effect on 7 January 2026, but they do not exempt you from verifying the design. Before buying roofing, sandwich panels and insulation, check whether the planned works fall within the expanded catalogue of investments covered by simpler procedures. It is essential to determine the type of building and its parameters, not its resemblance to a photo from the internet. Remember that an exemption from a permit does not release you from ensuring safety and meeting technical requirements. The designer should confirm the scope of documentation and the appropriate conditions for the roof and partitions.

In Poland, before building a house, you must establish whether the plot can be built on at all and choose the correct formal procedure. Check the right to dispose of the property for construction purposes, road access, utilities and the local plan — especially the building function and roof geometry. Where no plan applies, determine the route to obtaining planning conditions. Do not rely on floor area alone or on neighbouring houses; the designer defines the area of impact. It is worth linking the documentation and roof covering choice to the approved design before ordering material.
