What this work involves
Use a location-specific check through the Omgevingsloket and gather the required information. Consult the municipality or an adviser where needed. A design or quote is not permission to start.
- Location and work description
- Permit check and information
- Design and structural documents
- Discussion with the relevant authority
- Conditions and construction coordination
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Base design and specialist assessment on measured facade details.
What the drawing needs to explain
Draw a scaled elevation showing existing and new windows together. Resolve the roof-edge, wall and window junction before deciding from an atmosphere image alone.
Decide this before construction
Photograph retained details before dismantling. Check the dimensions of new components against the actual facade before production begins.
Compare the complete intervention
Allow a separate item for making good around the junction. The new wall may be precisely priced while adjustments to existing pointing, mouldings and finishes remain missing.
Cost factors for this service
Investigations, drawings, advice and authority fees vary by project. Define what is included.
Bring this to the discussion
Address, sketch, existing plans and previous correspondence.
Questions about the work
Can approval be guaranteed?

The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
