A CHF 20'000 louvred roof should not fail because of a form.
Retailers sell products, not permits
“This doesn't need a permit” is wrong in most cantons. A louvred roof counts as a covered seating area, a carport as a building. Both require an application.
Even small projects need planning
For a pergola or carport, the location, distances and documents must all fit together. We handle the preparation at the agreed fixed price.

Can I submit a building application without an architect?
The requirements depend on the canton and the project. Check whether a qualified plan author must be involved and which signatures are required. The power of attorney and the technical requirements are agreed for the specific submission route.
How long does it take to get a building permit?
Our turnaround for the minor building application file is 5 working days after receipt of payment and all the necessary documents. The duration of the authority's review is separate and depends on the applicable procedure, specialist offices, follow-up questions and any objections.
Which documents do I need to provide for the enquiry?
Give the address, the structure and the dimensions, and have photos and any existing plans or manufacturer drawings ready. For structures already built, include any letters from the building authority. The documents needed for the actual submission are clarified based on the location.
Can I use existing manufacturer plans?
Yes, as the basis for the check. They must match the product actually planned. We clarify which site plans, dimensions, forms, signatures or technical evidence are also needed.
