The Union Trust Building, commissioned by coal magnate Henry Clay Frick and completed in 1917, originally was a 240-store shopping arcade with 700 offices on its upper floors.

This 11-story Flemish-Gothic–style building has had several owners. The latest, Pittsburgh native Jon Davis, CEO of The Davis Companies, paid $14 million in 2014 with the intention of revitalizing it into an amenities-rich commercial center.
