About

dl-c is an architectural practice led by Patrick Devanthéry, Thierry Décosterd and José Antonio Ramos. Together, based on complicity and complementary architectural sensibilities, they have completed numerous projects throughout Switzerland.
 
 
dl-c is one of the defenders of rational and functional architecture. Far from wanting to impose their own signature, the office seeks quality. The integration of the site, the orientation of the building, the light, the programme and the aspirations of the client are all parameters that guide our architecture. At the basis of our practice is also the desire to develop innovative strategies based on ecological, social and economic factors for sustainable architecture.
 
 
dl-c is able to carry out all types of projects, be they new buildings, renovations or conversions. The firm handles all phases of an architectural project, from feasibility studies to completion, submission and site management.
dl-c is a team of 18 people, including a mix of experienced architects with extensive knowledge of architectural codes and a new generation who bring a fresh and novel approach to the firm. Together, they form a mixed, diverse, dynamic and complementary team that shares the same values and work ethic.
 
 
Kaedis sa founded in 2015 is a general contracting company led by Patrick Devanthéry, Thierry Décosterd and José Antonio Ramos. The company takes care of the construction and manages the management and completion of the site.
