Before undertaking major exterior work, individuals must take into consideration the need for numerous administrative procedures. Outdoor fitters (carpenters), for their part, must ensure that authorisations have been granted before starting a project.
What are the administrative steps to be taken?
Exterior design work is divided into two categories:
- Those who add more than 20m² of surface and/or modify the volumes of the house: a building permit is then required.
- Those that create a surface area of less than 20m² and/or modify the initial external appearance of the house: in this case a prior declaration of works is sufficient.
These administrative procedures are often painful because the time required for instruction is generally long (one month for a declaration of works and two to three months for a building permit). In addition, the files must be complete and often as precise as possible to speed up the process as much as possible and facilitate acceptance of the project.
Some examples ...
The installation of a gate or fence is subject to specific rules. There is no need for a building permit, but a prior declaration is required. It must be accompanied by precise details of the project (plans, materials, colours, etc.).
A pergola, whether it is attached to the house or free-standing, is subject to a declaration of works or a building permit, depending on its dimensions. Only dismountable pergolas do not require any administrative procedures.
Building a veranda requires a few applications. It all depends on the surface area of the new construction, but in any case it must be declared to the town hall. However, a building permit application is compulsory as it is an additional room. The use of an architect may be required in certain cases (dwelling of more than 170 m², reception of the public, classified areas, etc.).
There are also specific cases!
If the property is located near a historic monument, in a protected natural area or in a commune with a PLU (Local Urban Planning Scheme), certain specific rules may apply. All exterior work may then be subject to authorisation!
URBASEE, your best ally
The realism and precision of the URBASEE tool will allow you to visualise the project in real conditions and at real size in its environment. This solution, which projects the future installation in augmented reality, will allow you to integrate the insertion study into your client's file.
Also known as "site insertion", the insertion study is a graphic document that allows the representation of the construction project in its environment to be appreciated. It consists of inserting a 3D perspective rendering into a photograph of the existing site. It is expected that the document is representative of the reality in terms of architecture, materials and colours. The document allows the town planning department of your municipality to consider the impact on the environment according to the point of view used. The choice of the angle is important and reflects the main view of the project from the public road.
On-site insertion is a document that requires technical skills but with URBASEE, this obligation is made easier. Integrate the client's project into its environment using augmented reality, take a screenshot, print and your insertion study is ready!
