Aqua Tower vs Salesforce Tower

Comparing the Aqua Tower and the Salesforce Tower is interesting because they both rise in Chicago, IL, yet they were conceived by two different design teams, Studio Gang Architects and Pelli Clark & Partners, and were completed at different points in time. They were finished more than a decade apart.

This contrast within the same city allows us to see how different creative minds interpreted the evolving needs of Chicago across time.

Let's take a closer look!

The Aqua Tower is clearly the larger tower of the two, both in terms of height and number of floors. It rises to 859ft (261.8m) with 82 floors above ground, while the Salesforce Tower reaches 817ft (249m) with 57 floors above ground.

Aqua Tower also offers more total built-up area, a total fo 1,980,558 sqf (184,000m²), which is about 530,563 sqf (49,291m²) more than what the Salesforce Tower offers.

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 Aqua Tower and the Salesforce Tower were designed in line with the aesthetic conventions of the Contemporary style.

At the time, this style was at the height of its popularity. So both Studio Gang Architects and Pelli Clark & Partners followed what was in many ways expected of them, producing designs that fit comfortably within contemporary architectural norms, rather than breaking with convention.

The Aqua Tower follows a mixed-use model, combining commercial, residential, hotel and parking. In contrast, the Salesforce Tower has remained primarily commercial.

The Aqua Tower incorporates a -star hotel with 225 rooms.

The Aqua Tower offers 739 residential units.

The Aqua Tower also provides 1557 parking spaces.

The two buildings opted for different structural and facade solutions.

The Aqua Tower uses a Framed Tube In Tube system, which combines a strong central core with a perimeter tube of columns, while the Salesforce Tower uses a Frame system, that relies on a regular grid of columns and beams to sustain its weight.

And when it came to the facade, the Window Wall went with a Window Wall facade, which uses panels fitted between floor slabs, leaving slab edges visible, while the Salesforce Tower opted for a Curtain Wall facade, that uses a lightweight glass curtain wall hung from the structure.
