I like the trees on the roof. We live in Texas. Trees are good. That rooftop deck is going to be a very popular viewing spot of the Alamo. The view of it at night should be especially beautiful.

I do agree about the sand in the plaza. I'd mostly be thinking of mud when it rains and the possible dust issue in the dead of summer from all the foot traffic. Do they really want that getting inside the Alamo? I don't.

I don't know what to think of the glass wall. I can't say I'm a fan. I'd rather see the walls rebuilt with stone as original as possible if they're going for historical accuracy, or as Sigaven suggested, design a low wall for a seating area under the shade of the trees on the perimeter. Also, I worry the glass wall will become dirty from fingerprints/smudges and also the dust. I can't stand the glass they put up on the Tower of the Americas observation deck. It pretty much ruined the view because it's always covered in fingerprints and snot. I always tell myself I'm going to bring a bottle of windex and a roll of paper towels the next time I visit it. I also think it would be lost on a lot of people the significance of the glass wall - that it's intended to be a replica of the original stone wall. Most people will likely just assume it's a modern wall made of glass. They no doubt chose glass because it's cheaper and has a modern twist, but it also serves to increase the visibility of one of Texas' most important landmarks, and as a consequence, a major tourist destination.
