Seriously, to each his own. Some enjoy a blank concrete wall or floor. I see the same logic with a brick wall or street. Some don’t. I think the historic preservation topic is really based on architectural significance of a building as well as built-character of an area.
The warehouse district has a built character that’s worth preserving because it’s a collection of similar buildings but, to the best of my untrained eye, gives us no significant architectural value. The community has chosen to preserve this which is why Kane preserved a few walls of The Dillon warehouse into the newer construction. Same with Citrix.
We could argue the merits of their worth in another thread as well as historic preservation if you guys want to.
