A major renovation consists of clear phases. Knowing them tells you when which decisions are needed — and prevents costly changes during construction.
1. Introduction and feasibility
Wishes, budget and preconditions. A building survey shows what the property needs technically.
2. Sketch design and preliminary design
Layout, daylight and the first cost estimate. This is the moment to make the big choices.
3. Final design and technical detailing
Structure, building services and materials are defined. The budget is based on this.
4. Permits
Since the Environment and Planning Act (Omgevingswet, 2024), different procedures and timelines apply. Whether you need a permit depends on the work and your municipality’s environment plan. Always check this in advance via the Omgevingsloket.
5. Construction
Demolition, shell, installations and finishing. Weekly site meetings keep the schedule and budget in view.
6. Handover and aftercare
A snagging list, as-built drawings and installation manuals. This is followed by the maintenance period.
