Due to the rapid urbanization in Kenya, the building of new houses, the high density of people in small settlements, and the overuse of natural resources continue to negatively impact the environment. In 2007 the urban population of Kenya was estimated at 9 million while the projection for 2027 is 31.7 million. This rapid increase can result in poor living conditions and irreparable environmental degradation.

Through its Environmental Guidelines, NACHU aims to mitigate these issues by creating an environmentally sustainable process to buy land and construct homes. NACHU assesses the potential adverse social and environmental impacts before allowing a project to be implemented, ensuring the sustainability of both the environment and the construction project itself. In addition, NACHU provides technical advice and expertise on environmentally-friendly building technologies.
