What Does Architectural Advice from CREW-B Include?

​
- Initiation Phase – We assess your plans against the zoning regulations and check if a permit is required—or if the project can proceed under exemption.
- Design – We help turn your vision into a clear and buildable architectural design!
- Technical Advice – Whether it’s an extension, loft conversion, or full renovation, we create detailed technical drawings—suitable for permits and contractors.
- Structural Assessment – We evaluate if proposed changes affect load-bearing structures and deliver the necessary calculations and drawings.
- Permit Applications – We compile complete permit dossiers and submit them via the Dutch Omgevingsloket, including all required drawings and documentation.​

Do You Need a Permit for Your Renovation?
Not every construction activity requires a permit. Many projects in the Netherlands can proceed permit-free (vergunningsvrij), but this doesn’t mean you can build anything without restrictions.
​
Here’s the difference between permit-free and permit-required building:
🟢 Permit-Free Building (BOR Appendix II)
Certain home improvements are exempt from permitting under Dutch law (BOR – Besluit omgevingsrecht). For example:
​
Extensions are permit-free if they:
-
Are located at the rear side of the property
-
Extend no more than 4 meters deep
-
Stay within 30 cm above the ground floor level
-
Fall within the designated backyard zone and don’t change the building’s function
​
Dormer windows (dakkapellen) are permit-free if they:
-
Are installed at the rear (or sometimes side)
-
Are no higher than 1.75 meters
-
Stay within the roofline and are not placed on monuments
-
Have a flat roof and maintain proper distance from roof edges
​
- Important: Permit-free does not mean rule-free. You must still comply with the Building Decree (Bouwbesluit) and relevant civil law regulations (e.g. neighbor rights).
🔴 Permit-Required Building
A permit is mandatory if your project does not fall within the limits of permit-free construction. Examples include:
​
-
Structural changes (e.g. removing load-bearing walls or altering floors/roofs)
-
Modifying protected buildings or buildings in designated heritage zones
-
Dormers at the front or exceeding permit-free dimensions
-
Extensions that are too deep, too tall, or in unauthorized locations
-
Changing the building’s function (e.g. office to residence)
-
Conflicts with the zoning plan (bestemmingsplan)
