What helps you choose
- Start with how you want to use the attic.
- Discuss the dormer and the interior finish.
- Whether a permit is needed depends on your situation.
Decide what the attic should become
Do you want a quiet workspace or a bedroom with storage? Note furniture positions and existing features you want to keep. Consider access to the floor and everyday use too.
A bedroom requires a different discussion from a storage attic needing more light. Describe the function first, then have the potential space gain and construction assessed for your roof and home.
Discuss the complete scope
Ask about the same components in each proposal. Describing only the outside does not tell you what will be finished inside.
| Component | Your preference | Also ask |
|---|---|---|
| Windows and use | Light, views, privacy and opening sections | How are ventilation, operation and maintenance included? |
| Appearance | Colour and relationship to the home | Which materials and finishes are specified? |
| Interior space | A ready-to-use room or just the shell | Which walls, windowsills and finishes are included? |
Check your own situation
Informatiepunt Leefomgeving advises homeowners to use the permit check for a dormer. Its roof position, design and any special status of the building or area may matter. ‘At the back’ is not a complete assessment on its own.
Complete the check for your own plan and address. Discuss questions about the result with the municipality or an expert. This keeps appearance choices aligned with what is possible at that location.
What should you bring to the first conversation?
Photos of the attic and exterior help explain your idea. Add existing drawings if available. You do not need to climb onto the roof or establish technical measurements for this preparation.
List what you expect to use once the work is done. Is it just a new dormer, or should electrics, heating, flooring and painting be included? State who will arrange any separate work. This clarifies what the proposal must cover.

Avoid these three pitfalls
- Comparing only dimensions or a base price.
- Assuming no permit is needed based on a photo or neighbours’ experience.
- Confusing a complete attic finish with installing the dormer alone.
