TJCA is a multidisciplinary firm composed of architects, project managers, financial specialists, engineers, and building economists.
Established in Geneva since 1979, we are mainly active in Switzerland and occasionally in Europe.
Our goal is to provide integrated services covering every aspect of real estate projects, creating a link between clients, investors, and the construction sector.
Our passion and motivation lie in taking part in the construction process, whether in a limited or extensive capacity, depending on the required level of involvement.
