Your preparation in Bilthoven
Earlier openings, chimney and current walls
Municipality: De Bilt
Earlier openings, chimney and current walls
Mark known old openings and any chimney breast near the intended change. Collect records of previous work and note where the current wall layout differs. These elements can interact structurally, so describe the complete situation rather than only the new opening.
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.
