Andy Horn established his own architectural practice in 1998, called Eco Design – Architects & Consultants. Horn is widely recognised for his pioneering work in the field of green building in the South African context, with a special focus on natural building construction and community involvement. The practice places a strong emphasise on the use of local natural materials, involving user participation and on-site training. In 2004 the practice was awarded a Sustainable Building Best Practice Award for residential projects in Africa and in 2005 was awarded the Silver medal in the Holcim Awards for Sustainable Construction in the Africa and the Middle East region and was one of 15 finalists in the 2006 Global Holcim awards. In 2007 he was short-listed for a Daimler Chrysler Award for excellence in Architecture. Andy has held a part time environmental design lectureship post with the University of Cape Town’s Department of Architecture.
