Thank you everyone for the replies.
It was just announced this week: The Veterinary Bioscience Institute headquarters relocated from Philadelphia to this downtown Winston-Salem neighborhood, on East Third Street. They are now headquartered in the mouse lab I posted above.
I love how unusually rough the terrain is in Winston-Salem. It's not uncommon for buildings to rise 1-3 floors higher on one side than the other.
You're right about that warehouse. The Tarheel Textiles Warehouse is the elementary school's expansion building. It's directly behind the school and shows how great Winston Factory Lofts and the Gallery Lofts are for young families. These residential buildings are across the street from the school!
