This is the densest redevelopment market in Nairobi, and the economics turn on plot ratio. The difference between a scheme that works and one that does not is usually established before design begins — in what the plot genuinely permits, not what the neighbouring block achieved.
Kilimani and Kileleshwa have changed faster than almost anywhere in Nairobi. Plots that held a single bungalow a decade ago now carry apartment blocks, and most work here is redevelopment rather than building on virgin ground — demolition, then a considerably denser structure on the same footprint.
That density is the whole commercial case: developers are buying plot ratio, and the difference between a viable project and a marginal one is often a few floors. It also means the constraints are real — neighbouring buildings are close, site access is tight, and the structure has to work hard.
