About South Nairobi
South Nairobi is a diverse region combining middle-class residential estates (South B, South C), the city’s industrial hub, and newer developments near the airport. The area is defined by major roads including Mombasa Road, Lang’ata Road, and the Southern Bypass.
South B and South C are established neighborhoods popular with families and young professionals due to their proximity to the CBD and affordable housing options. The Industrial Area is Kenya’s manufacturing heartland, home to factories, warehouses, and logistics companies.
Recent developments include Imara Daima and Syokimau, which have grown rapidly since the Standard Gauge Railway (SGR) terminus opened in 2017.
