Kenya has a large housing deficit which is growing every year and is increasingly prevalent in urban areas including Thika. According to the Ministry of Housing, the current annual housing deficit is estimated at 156,000 units per annum based on the population growth and urban migration currently taking place. The pace of construction is limited with only 50,000 units constructed and the deficit filled by growth in slum dwelling and poor quality traditional housing (Walley, 2011). Makongeni serves as an economic and residential hub of Thika town. Makongeni was conceived in 1970 with the intention of providing sufficient plots to accommodate around 60 per cent of the predicted population growth in Thika.The rate of construction of buildings in Makongeni is high to accommodate the rising number of people looking for settlements. The major concern is that almost none of the building adopts the green sustainable design or technologies available in the market during their construction or occupational phases. Thus there will be an increase in the consumption and demand of building materials, energy, water, and improve indoor environmental health which in the long run will not be sustainable. This research seeks to assess the level of sustainable building designs and explores technologies that can be incorporated into building design to make them sustainable.
