EHDO was established in 1995 as Earthhouse by Giles Hohnen, a designer and artist who was at the forefront of rammed earth building design and construction in Western Australia since the 1970s.

Since this time EHDO has broadened and evolved into a small, dedicated building design studio under the directorship of Dimitri Kapetas and Dave Delahunty, focusing on creating contemporary, socially and climatically responsive buildings for residential, commercial and public projects.

We use the specific physical, climatic and social context of the region to inform all our design decisions in order to create integrated buildings that belong to their place. Factors such as sun, light, breezes, topography, vegetation and materials are explored along with the careful consideration of clients needs. From this analysis we produce designs that have the appropriate balance of innovation and tradition to provide buildings that are both responsible and delightful without relying unnecessarily on complex, specialised systems to achieve comfort.
