5.3. New/External Building Works to a Property in France

In relation to external works, the main rules in relation to planning consent are as follows:

5.3.1. Garage/Outbuilding

A planning application is required if the external surface area is greater than 20m²; otherwise a works declaration is all that is necessary. Be aware, however, that if the building is being constructed near the boundary of your property, you may not be able to do so, due to controls on 'overlooking'.

5.3.2. Conservatory

A planning application is required where the conservatory is greater than 20m²; otherwise it is a works declaration. The rule above regarding building at the perimeter of your property applies as much to conservatories to other buildings and extensions.

5.3.3. External Swimming Pool

If the pool exceeds 10m², but under 100m², then a works declaration is required. If the pool is over 100m² or has a cover above ground that exceeds 1.80m in height, then a planning application is required. Below 10m² surface and 1.80m height no consent at all is required. Above ground pools do not need any consent, unless they are greater than 10m² or higher than 1.80m, and they are installed for a period in excess of three months. Once again, as above, be aware of constraints on constructing near the perimeter of your property.

5.3.4. Caravan/Mobile Home

If you are proposing to live in a caravan/mobile home in the grounds of the property whilst you undertake renovation works, then you are likely to need planning consent if you propose to live in it longer than three months. If the mairie deem no planning consent is required, you would be wise to get written dispensation. A caravan parked in the grounds only for occasional holiday use needs no consent of any kind.

5.3.5. Boundary Walls/Fences

The local council have discretion to decide whether they wish to adopt a control procedure. If they have not done so then, provided the new wall/fence is under 2 metres in height, no procedure is required. Above 2 metres in height then a works declaration is normally required.

5.3.6. Leisure/Camping/Caravan Sites

If you wish to establish a camping site or leisure facility, then you will need to submit a rather particular type of planning application called a Permis d'Aménager.

5.3.7. Wood Cabins/Log Houses

If you wish to construct an informal wooden building in your grounds, then you will need to submit a works declaration if under 20m² external surface area, or a planning application if greater than this amount. The planning laws are silent of the rules governing 'trees houses', presumably because they are only applicable to the control and occupation of land. You would be best to discuss with your local council.

5.3.8. Solar Panels - Ground Level

Whilst the installation of solar panels on the roof of a property requires a works declaration, there are no formalities for their installation on external ground areas unless they are located within a conservation area.
