Verandas, with the paperwork explained
Declaration or permit? It depends on the square metres.
We draw your veranda, tell you which formality applies in your town, and prepare the plans and forms for the town hall.

Good to know before you build
From 5 m², the town hall has its say
Up to 5 m²: no formality. From 5 to 20 m²: a prior declaration, up to 40 m² in an urban zone with a local plan. Beyond that: a building permit.
Over 150 m² in total, an architect is required
If the veranda takes the whole house over 150 m², the permit must be drawn by an architect. In a protected area, the heritage architect gives an opinion.
A closed veranda is taxed, a pergola is not
A closed, covered veranda creates floor area: the development tax applies and it is declared to the tax office within 90 days. An open pergola creates none.
In a block of flats, the general meeting votes
A veranda on a shared terrace or that changes the facade needs a vote of the co-owners before the file goes to the town hall.

What we take off your hands
Measured and drawn for your house
We measure the facade, the ground and the sun, then draw the veranda in plan and elevation before any quote.
The planning file prepared
Prior declaration or building permit: we prepare the plans and the forms, you sign and file them at the town hall.
Made to measure, fitted by our team
Profiles cut to your dimensions, glazing chosen for the side of the house, foundations and fitting by our own fitters.
Ten-year guarantee
A veranda is a construction: ten-year insurance, two years on blinds and motors, one year to put anything right.
