Corner views of the 23-story office building Hilcorp has been planning for the now-rubble-filled site of the former Foley’s (and more recently, Macy’s) retail box on Main St. between Lamar and Dallas surfaced on a few websites last week. The drawings of Ziegler Cooper’s design show a glass-faced structure doing the half-podium trick, blending 7-or-so garage levels into the main tower shape on one side, but letting it stick out on the other. That “other” side faces Main St.; on the Travis St. side (pictured above and in the last rendering below), the hide-a-car floors fit into the building’s northwest-facing curve, which pulls back to make room for a vehicle drop-off driveway loop and a couple of corner plazas. But what’s happening on the rail side?
