Our rear dormer turned out to be permit-free. The drawing was ready within three weeks and the contractor could get straight to work. Clear communication via WhatsApp.

Roof extension on our 1930s house. The permit sailed through the aesthetic review first time. Excellent guidance throughout the application, they handled everything with the municipality.

Everything arranged for our rear extension: drawing, structural calculation and the building permit. Fixed price upfront, no surprises afterwards. Very pleasant.

Excellent drawing for the facade alteration. The municipality had a follow-up question, which was handled promptly. Slightly longer lead time than expected, but overall satisfied.

Ridge raising on our terraced house. The 3D design was a huge help in seeing what it would look like before we started. Real craftsmanship and great advice.

Our attic converted into a bedroom with dormer. They gave great advice on what could be done permit-free, which saved us time and money. Highly recommended.

Extension in a protected townscape, not an easy process. The drawing met the requirements exactly and aesthetic review approved it. Impressive work.

Structural calculation for a wall opening on the ground floor. A clear report that the contractor understood immediately. Response time could occasionally be a little faster.

Full-width dormer for an extra bedroom. A great design at a fair price. Recommended for anyone searching across the Netherlands and not just a local firm.

Had a conservatory drawn on the garden side. Great advice about what was and wasn't possible, and the drawing was done in no time. Excellent service, handled entirely remotely.
