you are wrong about 4 tall buildings in one Zone. i tried to post above areas like KIJITONYAMA, UPANGA ,AND SAM NUJOMA STRIP. Go read and you will understand. we are very close to what NAIROBI have done, imagine we had no all those towers 5 years ago, look at your FLYOVERS AND INTERCHANGE, most of them are on advanced stage,some even landscaping not done, you can say you are miles away if those road projects were done 10 year ago, on monday we are launching the construction of our 2nd flyover (3 LEVEL INTERCHANGE, and BRT phase 2, 3 and 4. ,about Our SGR project, we alread have a contractor and the deal already signed . I can say you are steps away for housing estates although in Dar , they are also coming up everywhere. one thing you are untouchable though is the multinational regional offices coming in Nairobi.
BTW there are 8 New Buildings with 30-35 storey in one Zone you suggested [POSTA
