Why this won't work: You can't build a startup cluster to "renew an area".
It doesn't work like that. Old Street works because the location is decent (safe and well connected), it's cheap and the other companies there. The area has to attract people who want to work there and you can't artificially build that.
The location they're proposing put this new tech area goes through the area known as "murder mile". Yes it's cheap, but it's high crime rate means startups aren't going to locate there. It would be like trying to build a startup cluster in the Bronx because it's near the NY startup community.
