Not in these figures. Budget for these separately:

Professional fees: architect, structural engineer and quantity surveyor (get quotes through JengaCost's marketplace).
The land, and its search, survey and transfer costs.
Water and power connection fees.
Furniture, curtains and appliances.

Figures are budget estimates from JengaCost's dated rate library adjusted to Nairobi, not quotations. The ranking is worked out from the priorities you set, not a judgement that one house is better. See questions and answers.
