I think the Fort can do just fine with or without a fantastic skyline. They look great on postcards and brochures, but they don't make a better city. If something with some height gets built there and John has to retake the banner photo, I'm okay with that. (Sorry, John.) If another tower or two gets built in a more central location to fill things in a bit more, having that new tower on the edge makes it that much better.
And if I wanted to build a vanity tower, that'd be a pretty good place for it because there is not likely to be anything built that blocks the view of it for like 330 degrees around. It'll stand out pretty much everywhere on I-35W and I-30. And it would have pretty good sightlines up Main & Commerce.
In the end, though, whether it makes the skyline better or worse is pretty subjective and that's about all I can think to say about it.
Back to the use of the parcel...
Maybe I'm more worked up about what I see as ingress/egress problems than I should be, but I've been trying to think of uses that would work with that if it is a problem.One option would be having traffic enter only on the Lancaster side and exit on the Main side. I can think of uses that would work for that but none of them are attractive. One thought is that if it is primarily associated with the business, activities or population downtown, then arriving from most of downtown and entering from east-bound Lancaster (by car or bike or shuttle or whatever) and then leaving on north-bound Main to return downtown isn't that big of a deal.
Another possibility is having uses that need space but have relatively few people or uses where the coming and going is spread out (like the Fort Worth skyline) and not necessarily peaking at peak traffic times.
Today's suggestion: a data center; technical classes; tech incubator; some sort of Fort Worth professional technical society thing; 24-hour virtual/on-demand office space; 24-hour meeting space; 24-hour Internet cafe. Still fermenting wine in the basement because I could use some right about now and still have the garden and outdoor casual gathering spot on the roof because every building should have that.
Lake-Flato designs the building.
