Remnants of Homes in Downtown Austin

You can see the big skyscrapers in the first pic that have increasingly crept up recently in downtown Austin. Then you see a bunch of old houses. Some have been turned into restaurants and office buildings. Some still look like residences. Yo no se. Its all on the same block as I walked and circumnavigated it. The house with the red paint and old wood siding is the most mysterious to me. See the rocks holding it up? They're right next to the AC unit. Stain glass in one window and old curtains in another. The other side in the old alley has doors and windows that are boarded up. How long before those vines overtake the whole damn structure?
