Your preparation in Castricum
Connecting to an existing extension

Connecting to an existing extension
Collect the extension’s drawings and any calculations or foundation details. Show the desired opening at the junction with the original house. Different building phases can affect the support arrangement, floor levels and repairs, so include the whole connection in the brief.
What to send with your enquiry
- Your address, postcode, property type and floor, with a sketch showing the desired opening.
- Available building drawings, earlier calculations and photographs from both sides of the wall. Mark uncertain details rather than guessing.
- Your preferred timing and finish, including any related kitchen, flooring or service work.
