Given the orientation of this building, its height and architectural design, I think a hotel would be the best use for this building. One downside is the entire northeastern facade contains no windows, but I suppose that shouldn't be too much of an issue. This building will likely be renovated regardless. Other than that drawback, I could see this as a good possibility of a hotel. My reasons include:
- Good "L-shape" layout
- Parking lot could be replaced with underground garage with rear (William Penn Pl.) entrance and an expansion on top.
- Existing high demand for hotels given the strength of the economy and the current occupancy rates overall for the Pittsburgh region
- Close proximity to the Convention Center, several offices along Grant Street, Amtrak and Greyhound.
Office space could also be a good use, but I am unsure of what upgrades would be necessary for class A status. There are some companies still in search of class A office space downtown, and this building once renovated could satisfy some of those companies' requirements.
