We create places where people like to go and like to stay

TconcepT BV is specialized in architecture, concept design and place making across the globe. Our mission is to create places; places where people like to go and want to stay. We create Concepts where the aesthetic, functional, economic, feasible and sustainable aspects are all in full harmony.

We are closely engaged in all the design phases of our projects. We create specialized teams composed of local and international companies with expertise in market research, landscape design, light architecture, leisure and food & beverage. The Concept Design until the Schematic Design phase we design in-house. To ensure the quality of the design, TconcepT operates as a design supervisor for all other stages in the design process up until the project’s final construction and official opening.

TconcepT was founded in 2014 by former partners and directors of T+T Design and Multi Development Corporation. The international team at TconcepT, has had experience in design and architecture since 1982. Currently we are working on projects in 15 different countries.
