About us

May we introduce ourselves? We are André and Irène Roesch-Zwyssig, founders and owners of the company Trendline AG interior design concepts, which has been working successfully in the field of interior design for more than twenty years, implementing customer wishes, realizing them precisely and redesigning them on request.

During this time, we have advised hundreds of customers and, in close cooperation with them, realized numerous new worlds of living in home & office. In the process, we were able to make many helpful experiences regarding wishes, needs, fears and expectations. This has helped us immensely to become what we are now: Supportive mentors who successfully bring together different ideas and wishes into a coherent whole.

Here it is now our great concern to pass on these experiences in order to enable as many people as possible to have the quality of life that corresponds to their well-being. In order to create feel-good spaces on this basis, which increase happiness and satisfaction, but are also inspiring, motivating, relaxing and protective.

Our experience has also shown that the reward for both parties is the enthusiasm and realization that living feeling can be increased and has an added value, in the truest sense of the word.

Because besides the fact that the emotional environment has a great influence on our lives, the material value is not uninteresting. For property owners, with the right planning and professional implementation, we create added value for their property in any case. Not only emotionally, but also monetarily.
