It's unusual to have two construction sites so close together like this. I guess Birmingham might soon have a third project on the go with the Clyde Street development. By then however the TD building will probably be done.
It's been great to watch this little part of the city lose its shabbiness and small town feel over the past few years. After the next round of infill this is going to be a great medium density district with lots of population, great retail, some interesting natural features (gardens, Citadel), and some interesting architecture (library, Lord Nelson, etc.).
Spring Garden Road is proof that the sky doesn't fall when you allow new buildings. The interesting parts of the neighbourhood are still there. It's just gotten better and is in more demand now than it's ever been.
