The most common question before building a pergola, bioclimatic pergola or winter garden is about permits. The short answer: it depends on the type of building and whether the structure is permanent. In apartment buildings the owners' consent is needed, and in many cases you should consult the municipality. Here is what to check, step by step.
The short answer
Whether a pergola or winter garden needs a permit depends on three things: whether it is built at a detached house or in a building under condominium ownership, whether it affects the building's façade or common areas, and whether the structure is removable or permanent. Because rules can be applied differently by each municipality, we recommend consulting the zoning department of your municipality before you build.
Apartments and complexes: the management plan and the owners first
In buildings under condominium ownership, terraces, balconies and gardens are often common areas or change the look of the building. So:
- Check the building's management plan; it may contain rules on façade and common-area changes.
- Where needed, get the written consent of the owners' board. It prevents disputes with neighbours later on.
- Complex managements sometimes require a uniform colour and model; earlier installations in the same complex are a good reference.
Detached houses and villas
At detached houses no owners' consent is needed, but the zoning status, setback distances and floor-area calculations matter depending on the municipality. A permanent, glass-walled winter garden in particular may be treated as additional built area.
An open pergola is not the same as a closed winter garden
An open-sided bioclimatic pergola and a winter garden enclosed with glass on all four sides may be treated differently in practice. A louvred roof is for shading; once the sides are fully glazed, the area becomes a new enclosed space. Plan the project with this distinction in mind.
| Situation | What to do |
|---|---|
| Apartment terrace or balcony | Check the management plan, get the owners' consent, consult the municipality |
| Villa in a gated complex | Check the complex rules and the municipality |
| Detached house garden | Consult the municipality on zoning and setbacks |
| Restaurant, café, hotel | Check the municipality's rules for businesses and outdoor seating |
What we discuss at the site survey
At the free site survey we look at the fixing points, the façade and how removable the system is, as well as the measurements. We do not handle the permit process on your behalf, but we share our experience from past projects and prepare the technical information you can present to the management or municipality.
