Of course I would prefer (Philly) Center City's street life as opposed to getting a Comcast Center( their new tallest tower that really did wonders for its skyline). But right now, Houston's DT skyline hasnt changed in a real long time( even with some notable additions), and in the short term,I think an immediate impact to Houston's skyline would be more beneficial than adding more office workers. If this were a resedential project, I'd understand. But to an outsider, adding a 700 ft+ tower to the skyline will stay in that persons mind more than adding 700 office workers that that person will more than likely not even see first hand. I mean on average, what, an office worker spends less than 30 minutes actually on the streets of DT? If were lucky, a new office tower will bring along a retail storefront, and a restaurant or two. A visitor will recognize a change to the skyline more than the addition of a few hundred people, and a new office tower doesn't neccesarily equal more people/street life to DT, it may end up being just a transfer of office workers from an older building to a newer building. But, yeah, in the long term, I do think adding density to DT is better than just a few tall towers.
