CMA is not a tenant in any of Kenya Re properties.
Upper Hill plot someone has leased it and is selling used vehicles

CMA vacated years ago now nearly 10 years.
They went to Embankment building,Upper hill

Waste of money building a new office building in UH in the next 5 years.
KCB has vacancies.
Britam has vacancies.
UAP probably has vacancies.
And many more A Class buildings within 1 km of UH have vacancies.
Westlands has new office buildings coming up.

Government is expanding and snapping up office space in Upper Hill.
I guess you saw an advert by IRA and CMA looking for a building to acquire.
IEBC also wants to purchase a building in the same locality.

KCB is expanding and some of the functions/divisions are taking up the space in Upper Hill.
ODPP of Noordin Hajji took up Union Towers that belongs to UAP after European union moved out.
KDIC (Kenya Deposit Insurance Corporation) has taken 5 floors in Old Mutual UAP Towers.
Those are a few cases of what is boosting office uptake in Upper Hill and that is why government is expanding the roads and infrastructure there.

So 5 years from now the scenario will be different and putting up an office building will not be a waste of money

Am not sure whether the Israeli embassy has got anything to do with the lack of occupancy in the building. In any case, next to it there is 4th or is it 5th Ngong Avenue building which is fully occupied. The newly constructed Tourism Fund building also neighbour the embassy and has some tenants already. Besides, the Prism building has lately put up a huge banner (almost covering the entire height of the building) looking for tenants. I suspect the architectural design of the building, which can give you a headache even from the outside, is entirely to blame for the lack of occupancy.

You got to feel pity for the proprietors moreso if they put up the building using credit facilities.

Ati, "The building is overlooking Israeli embassy hence no tenant there coz of security reasons." given the Israelis are switched on and could have stopped the construction in some form or fashion had they wanted to.
As you mentioned, there are so many other buildings close by.

Middle-class residential with mixed use,where is the land.
The ones they own are in court due to ownership dispute e.g Kiambu road,Shanzu

Which are these on Kiambu rd and Shanzu?

These are provided for.
I was referring to the UH plot. If they build middle-class apartments (Chinese style) in a skyscraper with a mixed use component. Not GTC, not fancy, not large... something affordable for singles and young couples (DINKs). NOT another office building in the next 5 years.

The glut in office space in Westlands is too much.
New buildings are coming up yet the roads are narrow
