A rough comperative analysis of the two construction layouts seems miles apart though. Both on the capital input and the returns on investment fronts.
The single storey units will cost just under KES 200k per unit meaning 100 units will cost about KES 20 million.
The returns from these units will be in the region of 500k to 700k per calender month assuming 100% occupancy. Recouping the capital invested in just over 3 years
Whereas with a high flat KES 20 million investment will probably finish 12 to 15 units. The returns on the completed units will be just under KES 100k.
So it will make economic sense if l was to demolish the single storey units after say 10 or 15 years and build high rise flats
From experience, the maths given is skewed.
1. Going Horizontal:
20 units will fit comfortably on 1/8th for a 14ftx14ft internal dimensions. Therefore with 3/8th, you can do 60 units - ground floor only. If you choose to go up, you could lose 5 units coz of stairs, corridors. Hence 100 is a good conservative number, in theory you can do even 110 units, depending on plan.
200K per unit for bedsitters is on the lower side. 250K per unit works assuming you are not going up, i.e. ground floor only. With minimal chumaz, basic finishes, basic roofing, basic foundation.
Should you choose to go up one floor, then the cost per unit goes up to 350K per unit, going up has additional costs - extra slab, stronger foundation.
2. Going Vertical.
On 1/8th, you can do 12-15 units of bedsitters per floor when going up. 20m is enough to finish a 3 floor (G+3) building with the right cost management technique. Hence 20m can get you 50-60 units.
I suggest you start with 1/8th and go horizontal, but with a very strong foundation, such that you will not need to bomoa anything in 10-15 years. Invest strongly with a strong foundation, and see the costs for 1 floor.
