TJCA is a multi-disciplinary group of architects, designers, project managers, interior decorators, engineers, financial planners and building economists.
Established since 1979, we have been mainly active in Geneva and from time to time in Europe.
Our team of 24 collaborators can ensure all stages of managing, from the beginning to the end, concerning the constructions, design and realization of your project.
Our aim is to provide services covering all aspects of property management, building a bond between Clients, Investors, and the construction realm.
Our pleasure and motivation is to participate, be it in a limited or extended manner, in the construction process, in function of the required level of implication.If you wish to submit a project, do not hesitate to contact us.
