A 1980s terraced house in Zwolle-Holtenbroek got a spacious dormer on the front. The house fell within the permit-free dimensions, so the manufacturer could use the drawings directly. The dormer was in place within the agreed planning.

The owners of the property in Holtenbroek had an attic room that was barely usable: the ceiling started at just 1.4 metres and there was only one roof window for light. The room was used as a storage room, but the aim was a proper children's bedroom. The municipality of Zwolle applies strict dimensions for permit-free dormers on front roof surfaces, which left limited margin.
We carefully verified the Zwolle conditions for permit-free dormers on front roofs: width maximum 4.6 metres, height maximum 1.5 metres and at least 0.5 metres behind the ridge. By designing the dormer to exactly the maximum dimensions, we achieved the optimal result within the permit-free framework. The drawings contained all the dimensions the prefab manufacturer needed for direct production.
After installation of the dormer the attic room has 6 m² of extra usable floor area and a headroom of 2.1 metres in the middle section. Three large window sections bring plenty of daylight. Because the dormer was permit-free, no application had to be submitted and the contractor could start straight away. The total lead time from order to installation was by arrangement.
