Firstly I'm not aware of anywhere in my post that I compared this city to London.
Secondly City Quays is not under construction. A part of the city quays plan is. Brunswick St. on the other hand may have been bought but that is not indicitive of any construction taking place any time soon. Note I named Bedford Sq, The Novotel, The Odyssey, and TQ as well. There's also Queens Sq, Montgomery Street, the 10 story thing on Dublin Road, Olive Tree House etc.
The recession put an awful lot of developers under yes I agree. We are now out of recession and have been for a few years but construction wise we are yet to see the recovery at all. My point is as a skyscraper/architecture enthusiast (like everyone here) I would like to see construction. Not renders and constant updates with yes work will begin soon.
No you didn't you moaned about nothing happening and your annoyance that multi-million development projects aren't happened, I used London as an example to illustrate that developments need finance and finance is only provided when the development can demonstrate an economic return, especially now given how many banks and businesses were badly burnt by reckless property lending.
City Quays IS under-construction, it's a phased development subject to market demand and always has been. As mentioned above CQ1 is under-construction, CQ2 has just been awarded permission and BHC are seeking an operator for the planned hotel, something they wouldn't do if they didn't plan to start construction on that soon.
Titanic Quarter's developer is in the process of re-financing their debt in order to make further development possible.
Odyssey Quays is a phased project and they only have outline permission. Work will commence on that once they secure full permission for each respective phase and once they have finance.
Bedford Sq was a massive office building planned before the crash and something that was going to be impossible to see an economic return on during the recession, a recession that we haven't been free from for years. economic recovery in NI has been slow and fragile.
As for the other developments. The student residential building on Dublin Road was approved a few months ago and since then I've seen workmen carrying out soil testing and piling samples to asses the ground, something you don't do unless you plan to commence work in he coming few months, which I believe is the case. The other developments you mention are primarily apartments, a market that is yet to see a substantial price recovery in Belfast, thus making them difficult to finance.
You fail to understand the reality of market conditions, finance restrictions and generally economic recovery. You also ignore the fact that while we're not seeing skyscrapers popping up all over Belfast we have projects under construction in Belfast representing nearly £1bn of investment. Projects such as City Quays, University of Ulster's Belfast campus, Queen's University's various projects and the Ulster Hospital's Phase B project, not to mention lots of other smaller projects.
