We believe that the build environment has a direct influence on the quality of our lives and set out to create joyful spaces that are uplifting and inspiring to use.​​

We aim to create bright spaces flooded with natural light.

The play of light and shadow is key to bring our architecture alive and the use of natural materials and vegetation often enhances the users’ experience and well-being.

Our design approach follows closely the concept of legibility, in which every element of the design is expressive of its function and as such contributes to the overall aesthetics of the building.


Sustainability and the analysis of the specific site conditions are at the heart of our design and often define the very concept of our buildings. This involves careful consideration for the climatic conditions such as sun, temperature, wind, rain and snow etc. as much as the optimization of views, natural daylight and use of renewable energy resources available on site.

Our designs are based on a detailed understanding of the functions they must fulfill and we promote the idea of flexibility as a means to ensure that a building can adopt to changes in the original brief and function over time.


We combine the use of up-to-date technology with traditional and cultural related building methods depending to the individual project requirements and locations.
