These facts are, of course, fluid. Nothing is concrete until it's built in concrete. So things may have changed radically, but here's the latest I have on 108 N. Jeff.:
Name: 108 North Jefferson
Height: 430 feet
Use: Rental apartments
Architect: Solomon Cordwell Bunez
Office space: 93,000 square feet
Retail space: 12,500 square feet
Garage: 5 stories
Parking spaces: 246
Naturally a swimming pool and all the usual amenities are planned.
Last I heard this is still in the permitting stage. Traffic and other studies have to be done first. If anyone has any better information, post it here.
