Hi!
I am new to this forum and I would like to introduce myself.
I am an American citizen, with Russian origins, who lives in Switzerland since 1997.
Last year I have founded an architectural company, together with a Swiss architect - Arco Ligne Architecture SA in Renens, VD.
We can do property evaluations, new building and renovation projects, interior design, and actual building-site management.
We are looking to meet new clients, people of the same profession or participate in discussions on architectural topics. I will be happy to answer any questions related to construction in Switzerland.
Thanks a lot

Welcome to the EF, Arcoligne. Hope your contributions will go beyond discussions on architecture and building.

By the way, a friend of mine has bought a new apartment and the finishers didn't do her bathroom the way she wanted it. They refused to redo it. Is she entitled to compensation?

Thanks, Argus.
Did your friend have detailed plans of how works should be done or at least a detailed order of elements for the bathroom? If she can prove that she didn't order what they installed or that the installation has defects, she should be able to claim a re-installation.
In the case that the work is poorly done, she can find an expert, another company that does similar installations, get a report and demand that work is redone in a fixed amount of time, otherwise another company will do the work and bill the 1st company.
All legally working building-related companies are obliged to have an insurance, so if their work has defects, they can claim from their insurance. The client needs to insist, in a written form, for mistakes to be corrected.
