We inspire sustainable, contemporary brick architecture and building design in all areas of the built environment: commercial, residential and landscape.

Passive Solar Design and Clay Masonry


Passive Solar Design aims at realising thermal comfort in a building through correct design and operating it with nature in mind. By combining natural energy, from elements like heat from the sun, with a thermally efficient material like Clay Brick, the building responds passively, resulting in a minimal amount of imported energy required.

Not only does this result in significant cost savings over the life cycle of the building, it also lightens the burden on the environment through reduced energy consumption.
