Permits for a house extension

Permission for an extension depends on the location, design and applicable rules. Assess the actual proposal before ordering materials or agreeing a construction start.

Two aspects to check

Building-quality rules and local planning rules can involve different assessments. Use the Omgevingsloket for the address and proposed work, and seek advice where the outcome or required documents are unclear.

Prepare a clear design

Dimensions, position on the plot, appearance and the connection to the existing home help define the proposal. Structural drawings and calculations may also be needed for the project. A standard product brochure is not the complete design for every site.

Coordinate responsibilities

Agree who prepares documents, checks requirements and submits any application. Include sufficient time for the relevant procedures and distinguish that time from the construction programme.

Budget separately

Design, investigations, structural work and municipal charges are different cost items. Ask for them to be identified in the quote. Permission-free work must still meet the applicable building requirements.
