One of the largest buildings to be erected in Chicago's "New Eastside" neighborhood since the Aon Center, 340 On The Park fills in the final gap in the Randolph Street skyline facing Millennium Park and Grant Park. It also provides a link between the East Loop's architectural past and future.

This is an area that saw its first residential development in buildings like The Buckingham and 400 East Randolph. Both are substantial properties, but neither is particularly architecturally inspiring. They are symbols of the eras in which they were constructed; when exposed concrete beam grids were a good thing, and apartment blocks were more utilitarian. Fast forward to the 21st Century, and people living in apartment towers and condo blocks care quite a bit about what their building looks like, especially if they're spending millions on a new home in the sky. 340 On The Park satisfies this vanity by presenting a thoroughly modern appearance with glass curtain walls, and reflective geometries. But it also harmonizes with its neighbors.

To the west is the Blue Cross Blue Shield Tower, itself one of Chicago's better uses of glass. And to the east is the previously mentioned Buckingham, with is bays and channels presenting themselves to the world in all of its beige stucco glory. 340 continues the Blue Cross tower's blue glass aesthetic while blending with the Buckingham's concrete grid. 340 On The Park uses that grid homage as an opportunity to provide balconies, which the Buckingham is sorely missing. 340's footprint is also of similar size as the Buckingham, though it is nearly a third taller. At the time of its completion, 340 On The Park was taller than the Blue Cross Blue Shield Tower, but that won't last long as the height of BCBS is roughly doubling with the addition of 30+ stories to the existing structure.
