We build your dormer (dakkapel) on the roof or lift a prefab one into place by crane, and then finish the attic inside: insulation, plastering, electrics, heating, window sills, storage and paint. You get a detailed offer before anything starts.

One team for the dormer and the room behind it, with our own people and subcontractors we trust. Items with a link have a page of their own.
Built on the roof by our team, or made in a factory and lifted on by crane.
A flat or sloping dormer roof, cheeks in wood cladding or plastic panels, joined to the existing roof.
Wooden or plastic frames in the colour you choose, double or triple glazing, a ventilation grille if you want one.
The new walls and ceiling insulated and boarded.
Smooth walls and ceilings, ready for paint.
Sockets and lighting for the new room.
An electric radiator or electric floor heating, so the new room stays warm.
Window sills, cupboards in the knee wall, walls and ceiling painted.
A new floor across the attic.
From the drain in the floor to the mirror on the wall.

Why people choose us
Carpenter, plasterer, electrician, heating and finishing in one planning. You do not have to find a second company for the inside.
Built on site gives more freedom in size and shape and no wait for production. Prefab takes longer to make, then goes on the roof quickly on the day.
The working area is cleaned before we leave each day, and we use tools that keep dust down.
We give a one-year warranty on our work, and we are insured against damage.

Questions
Send the form or call us. A photo of the roof and the attic helps; the price comes after we have measured on site, as a detailed offer.
That depends on your house, the side of the roof and the rules of your municipality. Getting a permit and informing the municipality or the owners' association (VvE) is your responsibility; we do not arrange it. We can tell you exactly what the work involves, so you can check the rules for your house.
Built on site, the dormer is made to measure on your roof, with more freedom in size and shape and no wait for a production line. A prefab dormer is made in a factory and lifted on by crane: production takes longer, the placing itself goes quickly.
