An extra room, home office or studio without building an extension. Your garage or outbuilding already has the space, it just needs to be made fit for habitation. We produce the drawing with change of use from €995, ready in 4 weeks, and arrange the building permit if required.
Converting a garage means making an unheated, uninsulated space habitable as an extra room, office or studio: insulating, closing off the garage door and connecting to the utilities. Drawing with change of use from €995, ready in 4 weeks (express 1-2 weeks). If a permit is required, allow 8 weeks for the municipal decision.
Converting a garage into living space means making an unheated, uninsulated space ready to live in: insulating, sealing and connecting to the building services. These are the elements we draw.
A new insulated floor build-up is laid over the existing garage floor, often with underfloor heating. This ensures compliance with insulation requirements for residential use.
The garage door is bricked up or replaced by an insulated facade with a window frame or shopfront for daylight and insulation.
A window or glazed facade in the new wall ensures sufficient daylight. Custom width and layout, in keeping with the property.
The existing roof or ceiling receives an insulation package. Crucial for comfort, acoustics and your energy label.
The existing walls are insulated from the inside or cavity-filled. This turns a cold garage wall into a warm living wall.
Connection to electricity, heating and mechanical ventilation. Living space requires adequate air circulation and power outlets.

Converting an attached garage is often permit-exempt, but using it as living space is a change of use that must comply with the zoning plan. We assess your situation and arrange the permit if needed. From €995. Request a no-obligation quote for your exact situation.

From a simple extra room to a full studio with its own facilities. We advise on what is permitted and what suits your home.
The garage conversion is insulated, enclosed and made habitable as an extra bedroom or home office. The fastest and most cost-effective route.
The garage door makes way for a wide shopfront with plenty of natural light. The garage becomes a bright, fully functional living space as part of the home.
A self-contained studio with its own facilities, ideal for a care arrangement, an au pair or rental. A building permit and change of use are often required.
Converting a garage is often the fastest and most cost-effective way to make existing square metres usable: the space is already there. Here is how it compares to an extension and a roof extension.
The renovation is often permit-free, but the change of use to residential space varies per municipality and zoning plan. A few typical situations.
Example project · extension · change of use · extra study room
Challenge: A family in Amersfoort was using their attached garage as a storage room and wanted to turn it into a proper home office. They were unsure whether it was simply permitted and whether the space could be made warm enough.
Our approach: We assessed the residential zoning and parking standard: the garage did not count as a mandatory parking space, so the change of use was feasible. We drew an insulated floor, a sealed garage door with new frame, roof and wall insulation and the connection to electricity and heating.
Result: 16 m² of extra living space, a light and cosy home office and a clean change of use. Drawing in 4 weeks, the conversion by the contractor in a matter of weeks.
Converting a garage is a relatively small intervention with a big impact. What you still need to know.
Converting an attached garage is often permit-free. However, using it as living space must be checked against the zoning plan: residential designation and parking standards. We verify this for your address.
SOURCE · OMGEVINGSWET 2026A garage is usually uninsulated. During the conversion you properly insulate the floor, walls and roof in one go. More comfortable and beneficial for your energy label.
ADVICE · Rc ≥ 6.3 new sectionA garage conversion often increases the living area and property value and can be co-financed through a renovation mortgage (up to 106% of the post-renovation value).
BRON · NHG.NL 2026Sometimes yes, sometimes no. The renovation itself (converting an attached garage beneath the existing roof) is often permit-free. However, using the space as living accommodation is a change of use that can conflict with the environmental plan, for example the residential designation or the parking standard. In that case, a permit is required. We check your situation free of charge.
The drawing including change of use costs from €995. Construction itself (by a contractor) is indicatively between €1.000 and €1.800 per m², depending on insulation, window frames, floor and installations.
This varies by municipality. Many municipalities apply a parking standard under which a garage counts as a parking space. If that space disappears, you often need to be able to park elsewhere or apply for an exemption. We check the zoning plan and parking standard for your address.
Yes, if converting to living space. The garage door is bricked up or replaced by an insulated facade with a window or glazed frame. This meets the requirements for insulation, daylight and ventilation. We draw the new facade layout.
We deliver the drawing within 4 weeks (express 1-2 weeks). If a permit for the change of use is required, allow 8 weeks for the municipal decision period. The conversion itself often takes a few weeks.
Yes. We draw garage conversions across the Netherlands. We do the drawings remotely; any permit or change-of-use application is submitted to your municipality. For every municipality we know or check the zoning plan.
