Zaandam · Amsterdam · Haarlem · North Holland
We take a renovation from start to end: stripping out, taking out load-bearing walls and putting in steel beams, new openings, extensions and dormers, then plastering, floors, kitchen and bathroom. One contractor, one planning, and a detailed offer before anything starts.

Why people choose us
Builder, electrician, plumber, plasterer and finisher in one planning. You do not have to find and schedule them yourself.
Temporary props first, then the steel to the calculation, then fire-resistant boarding, plaster and paint around it.
The offer lists the work and the materials. If extra work comes up, you hear about it before we do it.
We clean up before we leave. Doors are locked, lights off and the water shut off at the end of each day.

Questions
Both. From one new opening in a wall to a full house with an extension. When it is the whole project, one contractor plans all the trades.
The steel for a load-bearing wall follows a calculation by the Dutch structural engineer we work with. Permits and informing the municipality or the owners' association (VvE), where needed, are your responsibility. We can tell you what the work involves, so you can check the rules.
It depends on the size of the house and the structural changes. On average an apartment of 70 m² takes 5 to 12 weeks and a two-storey house of 150 m² 6 to 15 weeks. The planning can change once the strip-out is done.
The construction materials come from us and are in the offer. Visible and decorative materials, such as tiles and fittings, you choose and buy yourself; the offer says what and how much.
Yes. We check that your design works in practice and with local rules. We can suggest designers in the Amsterdam area; the choice stays yours.
Yes, a one-year warranty on our work. We are insured against damage, and our people hold VCA safety certificates.
We are based in Zaandam and work in Amsterdam, Haarlem, Alkmaar and the rest of North Holland, and further afield in the Netherlands.
