Garage conversion drawings across the Netherlands
An extra room, home office or studio without building an extension. Your garage or outbuilding already has the space; it only needs to be made liveable. We make the drawing with change of use from €549 incl. VAT and arrange the permit if needed. We plan delivery by arrangement.
Converting a garage means making an unheated, uninsulated space liveable as an extra room, office or studio: insulating, closing up the garage door and connecting the installations. Drawing with change of use from €549 incl. VAT. We plan delivery by arrangement (rush available for a surcharge). If a permit is needed, allow 8 weeks for the municipal decision period. You follow your entire application live in your own online file, from quote to delivery.
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.

1
Insulated floor
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.
2
Closed-off garage door
The garage door is bricked up or replaced by an insulated facade with a window frame or shopfront for daylight and insulation.
3
New window frame or shopfront
A window or glazed facade in the new wall ensures sufficient daylight. Custom width and layout, in keeping with the property.
4
Roof and ceiling insulation
The existing roof or ceiling receives an insulation package. Crucial for comfort, acoustics and your energy label.
5
Wall and cavity insulation
The existing walls are insulated from the inside or cavity-filled. This turns a cold garage wall into a warm living wall.
6
Services and ventilation
Connection to electricity, heating and mechanical ventilation. Living space requires adequate air circulation and power outlets.
§02 Quick check
Do you need a building permit?
Four questions, about 30 seconds. No obligation.
1
Is the garage attached or freestanding?
2
Does the facade stay the same or will there be a window or shopfront?
3
Is your property a (national) listed building?
4
Do you know whether a residential designation and parking standard apply?
✓ Often feasible, check change of use
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 €549 incl. VAT. Request a no-obligation quote for your exact situation.
§03 Costs
Calculate your garage conversion price
Indicative calculator. The drawing is a fixed price; the construction you commission separately through a contractor.
The build itself is then handled by a contractor (not by us):
Construction costs conversion± €28,000
* We handle design, change of use and (if required) the building permit. Construction is carried out separately by a contractor; indicatively budget €1,000 to €1,800 per m² for insulation, window frames, flooring and installations. Request a quote for exact drawing costs.

§05 Three variants
What will your new space be?
From a simple extra room to a full studio with its own facilities. We advise on what is permitted and what suits your home.
Extra room or home office
The garage conversion is insulated, enclosed and made habitable as an extra bedroom or home office. The fastest and most cost-effective route.

Extra space12-20 m²

§06 Comparison
Garage conversion vs alternatives
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.

SKETCH

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 area, a bright and warm home office and a neat change of use. Drawing planned by arrangement; the conversion by the contractor in a few weeks.
§09 Additional info
Change of use, financing & insulation
Converting a garage is a relatively small intervention with a big impact. What you still need to know.
Change of use?
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.

Include insulation
A 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 section
Renovation mortgage
A 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).
Sometimes 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.
Q02What does the drawing for a garage conversion cost?
The drawing including change of use costs from €549 incl. VAT. Construction itself (by a contractor) is indicatively between €1,000 and €1,800 per m², depending on insulation, window frames, floor and installations.
Q03Is it permitted under the zoning plan and parking standards?
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.
Q04Do I need to close off the garage door?
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.
Q05How long does it take?
We plan the drawing by arrangement; rush is available for a surcharge. If a permit is needed for the change of use, allow 8 weeks for the municipal decision period. The conversion itself often takes a few weeks.
Q06Do you work across the Netherlands?
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.
