A guy has put up a flat with 84 one bedroom units on 1/4 acre next to Thika road mall. Each going for 20k. Total income is Ksh 1,680,000 per month.

I don't know the cost. But the flat has about 7 floors (ground plus 6 storeys). Anyway assuming each unit is 35m2 at a construction cost of 20-25k per m2 the total would be about 60-73.5m. The plot is connected to sewer.

@657300, oltepesi is 68.3km from nairobi cbd

It will take 100 years for the area to warrant an apartment block type of house.

People build upwards vertically when the cost of acquiring extra land goes higher than the cost of laying a suspended concrete slab.
An acre of land in oltepesi is around kes 100k.

Untill the acre goes till kes 14m,in the year 2114, it will not be feasible to go the extra headache of vertical high rise building.

Sorry to hijack this thread, but wanted to ask a4architect.com, just how cost-effective and what are my %age savings in building using waffles in lieu of the usual concete/ chuma slab mixture?
What if I use chuma for trusses instead of wood?
This is for a 4-bdrm maisonette.

@bird_man and @a4, thanks for the advice. It seems then that it would be an idea for a time far away from now... I was banking on the fact that the Greater Southern Bypass was going to pass there maybe in the next 10 years. But 2114 hehehe I'll be an ancestor by then!

But, from some pdf i found here (jump to page 21 to 22), and doing some layman's analysis using Google Maps, it seems the Greater Southern Bypass will not reach that area. Anyone with concrete information?
