I emailed the folks at The Towers on Park Lane a couple of years ago, and they told me the building is 368 feet tall with 23 floors. Were you rounding up that 370 foot height from 368, or did you find that somewhere else?
The original height of the Vidorra Towers was supposed to be 292 feet with 25 floors. That height was obtained by another editor at Emporis from a friend of his that works with the architects who are designing the building. Since they've cut 4 floors from the building, I don't see it being anywhere near 370 feet tall. Infact, taking off 4 floors may make it considerably shorter - maybe only as tall as 245 feet or so.
I hope I'm wrong about that, but that's my feeling. The Shore, a 22-story condo tower in Austin that is being built, will be 257 feet tall. Still, at 200+ feet tall Vidorra Towers will stick up nicely in that area since there's nothing of similar height on that side of I-37, other than the spires on the Alamodome, (which are 300 feet tall), and the Staybridge which is probably only around 150 feet tall.
By the way, I love The Towers on Park Lane. Great looking building, and it's always a nice treat to see since it really towers over the area.
