Andy Horn is a qualified professional architect with over 24 years of experience with the design and construction of natural buildings. With a passion for the environment, he established his own architectural practice in 1998, called Eco Design – Architects & Consultants.

The practice has had a strong emphasis on the use of local natural materials, involving user participation and on-site training. Andy has often had to apply a personal hands-on approach to parts of the construction, involving physical building and training work. This continues to inform his art in the use of natural materials especially in straw bale, earth building and masonry dome construction. Clients have included: Namaqua National Parks, Mondi Forests, WESSA, Conservation International, International Fauna and Flora, Eskom, National Water Saving Campaign, South African Heritage Resource Agency, Hantam Municipality, City of Cape Town as well as numerous individual private clients, businesses and development planning teams.

Aside from practicing architecture, he has written numerous articles, published papers and photographs as well as illustrated books and pamphlets. He has also been a key note speaker and exhibited both locally and internationally. He also gives lectures on environmental design and holds natural building and participatory design workshops.
