The company was founded in 2010 with its headquarters established in Athens under the name “4CONCEPT”. Our firm deals with architecture, interior and exterior design, renovation and construction by undertaking many private projects such as residences, luxury apartments, hotels, offices and retail stores.

4CONCEPT  is ready to offer a complete project starting with an initial design and followed by the final implementation, along with every possible detail. We have extensive experience preserving clients’ corporate identity, as we have already accomplished a great number of projects so far. A strict schedule regarding deadlines for completion of the project, specialized crew and the use of modern designing and imaging methods, are additional key features of 4CONCEPT Ltd. The goal is to provide clients with an architectural design of their desired space by playing an active role in the designing and construction of the project through a 3D virtual reality program. The use of virtual reality will allow them to navigate throughout the layout of the space and to suggest possible ideas regarding the look and architectural design of the final project.

The Team

The basic team combines the multiannual experience of:

Panayiotis Andronis – Interior & CAD Designer
Konstantinos Roussakis


Our philosophy is to provide individual refinement for every discerning client and to contribute in the establishment of new standard qualities for interior and exterior fit-outs. Imprinting, studying, designing and applying various ideas are the four steps to creating a final project, while the quality of the material, innovation and technology constitute the reasons for our company’s success. Understanding and respecting the timetables and costs of excellent designs is a priority for us and a main concern. We consider each new project as a challenge, as we work hard to satisfy each client’s distinctive style.
