One South Broad Building vs 1616 Walnut Street Building

Comparing the One South Broad Building and the 1616 Walnut Street Building is interesting because they both stand in Philadelphia, PA, and were completed within 2 years of each other, but they were designed by different architects.

This offers a unique glimpse at how rival designers approached projects in the same city during the same era.

The One South Broad Building is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 472ft (144m) with 28 floors above ground, while the 1616 Walnut Street Building reaches 308ft (94m) with 24 floors above ground.

Of course, each project may have faced different briefs or regulatory constraints, which we don't really know about and could also explain the outcome.

Both the One South Broad Building and the 1616 Walnut Street Building were designed in line with the aesthetic conventions of the Art Deco style.

At the time, this style was at the height of its popularity. So both John Torrey Windrim and Tilden, Register & Pepper followed what was in many ways expected of them, producing designs that fit comfortably within contemporary architectural norms, rather than breaking with convention.

The One South Broad Building is primarily commercial, while the 1616 Walnut Street Building is primarily residential.

Originally, the 1616 Walnut Street Building was designed for commercial, but over time it was converted to residential. The One South Broad Building by contrast has maintained its original role.

The 1616 Walnut Street Building offers 220 residential units.

The 1616 Walnut Street Building also provides 160 parking spaces.

Both the One South Broad Building and the 1616 Walnut Street Building rely on a Frame structural system.

A frame structure uses a grid of columns and beams to carry the building's loads. This frees the walls from structural duties, allowing for flexible floor plans and larger windows.

They also employ the same type of facade, a Masonry facade.

A masonry facade gives the building a heavier, more traditional appearance. It often conceals a frame structure behind it, creating the look of solid walls without carrying the main loads.
