@Sakangu I agree with you about the Prefabs. Those are Turkish designs, and though they may appeal to some, most people in Kenya have a different taste. Anything looking woodish for a wall, no thanks. Wood interiors, yes, all the time but can I have a whole quarry for my walls.
The concept of Satellite towns (Live, Work, Shop and Play) is catching up fast in Kenya [e.g. Superior Homes Msa Rd, Suraya's Fourways Junction Kiambu Rd among others]. Chiefly because of Security concerns, there is more appeal to such gated communities, yet with breathing space as each house is on a own piece of land.
The advice is, if you identify a reputable developer, jump in when they are selling such properties off-plan. When the concept is up and everybody is Waaao! Don't, you are too late. The dilemna lies in that, some of these developers are new in the country when they launch, and thus we have no back fall to dig out their histories. That is why buying concept on paper (and bushes on the site) is a huge risky undertaking, putting your 10% on the dotten line.
For-example, Superior Homes Msa Rd was selling at 3.2m and 3.8m in 2003 when they started for a 3 and 4 Bedroom respectively. This rose to 4.2m and 5m in 2007 respectively. If you want a house there today be ready to pay cool over 12m for a 3 bed bungalow. Reason, not because of rising steel and cement costs, but the concept now selling itself

So, risk big, jump in early for higher capital gains. Cheers.
