A prefab uPVC dormer costs on average € 6,500 to € 11,000, installed. A bespoke wooden dormer costs € 10,000 to € 20,000 or more. Width is the biggest price factor; window frames, glazing, crane access and a possible permit also count. Renovating an existing dormer costs € 1,500 to € 6,000.

On the rear side a dormer is often permit-free, as long as the design stays within the national rules — including sufficient distance from the roof edges and the ridge. On the front side, or on a roof surface facing public space, a building permit is almost always required, as it is for listed buildings and protected townscapes. Run the permit check on the Omgevingsloket or ask your municipality; a good builder often handles the application for you.

The installation itself of a prefab dormer is usually done in one day: in the morning the builder opens the roof, the crane lifts the dormer into place and the home is wind- and watertight again the same day. The lead time sits in the preparation: measuring, production and any permit. A bespoke wooden dormer takes several days of work on the roof.

uPVC is cheaper and low-maintenance: painting is never needed. Wood costs more but fits nearly any size and roof shape, and for listed buildings or protected townscapes it is often the only finish the aesthetics committee accepts. Exterior woodwork does follow the usual painting cycle of 5 to 7 years. Many builders combine: a wooden structure with low-maintenance cladding.
