BTA SA is the sunroom expert in French-speaking Switzerland

Your conservatory expert in French-speaking Switzerland

Do you like the idea of a conservatory but aren’t sure where to start, or don’t have time to manage the build?

No problem – we’ll take care of everything:

  • Handling the planning application
  • Drawing up plans for all trades
  • Coordinating all the businesses that are involved in your project

So you don’t need to worry about a thing.

BTA SA’s turnkey solution is tried and tested, whatever type of conservatory our customers choose: classic, gullwing or hipped, veranda (roof only) or apex roof, in aluminium or uPVC.

For over 30 years, we have been perfecting our techniques in conservatory construction, combining aluminium and glass and manufacturing all of the necessary build components ourselves in our own Sion workshop.

Once we’ve manufactured all the elements from the plans we’ve drawn up based on your requirements, we deliver the conservatory to you and assemble it on site at your home, using our own teams.

We manage every stage, from design to assembly, so we can ensure that we are bringing you the highest quality.
