Architect and team

Cesar Pelli & Associates, with as the lead architect, was the architecture firm in charge of the architectural design, in association with Langdon Wilson Architect.

Cesar Pelli & Associates was in charge of the architectural design, however, architecture is a complex discipline involving many professionals from different fields, without whom this building would have not been possible. We will surely be leaving out a lot of names here, but here is a list of the people we do know also played their part in making the 777 Tower a reality:

  • John A. Martin Associates in charge of Structural Engineering
  • Jones & Jones as the Main Contractor
  • Mitsubishi Electirc Elevators as the company in charge of the elevators system
  • South Figueroa Plaza Associates as the Main Developer

Architectural Style

The 777 Tower can be categorized as a Postmodernist building.

Postmodernism in architecture emerged in the United States during the late 1960s as a reaction against the starkness of the International Style, which part of the new generation of architects argued was too impersonal, sterile, and disconnected from historical and cultural contexts.

Postmodernism challenged the International Style's austerity by reintroducing historical elements and ornamentation, although this time not as literally as in the Neo-Classic buildings. Instead, they reinterpreted them within the context of modern materials and construction techniques.

Postmodern buildings often feature bold, contrasting colors, unconventional forms, and a playful blend of various architectural elements from different eras and cultures.

In the United States, Postmodernism was not just an aesthetic choice but also a philosophical stance. It represented a democratization of design, where architects sought to create buildings that were accessible and meaningful to a broader range of people, not just designers and intellectuals.

The 777 Tower was completed in 1991. By 1991 the Postmodernism movement was experiencing a transition. Critics argued that Postmodernism, initially a rebellious and innovative style, had become formulaic and commercialized, and so the trend started moving away from blending historical styles, irony, and playful ornamentation, and begun to give way to emerging architectural trends concerned with more present matters such as technology, ecology or sustainability.

The 777 Tower was kind of late to Postmodernist movement, which in some ways might make it seem older than it really is.

Spaces & Uses

The 777 Tower reaches an architectural height of 725ft (221m). It has a total of 53 floors, served by 32 elevators.

Ever since opening its doors to the public in 1991, the 777 Tower has mainly been used as Commercial space.

Materials & Structure

The 777 Tower uses a framed tube-in-tube structure , with steel columns and concrete, steel slabs.

A framed tube-in-tube structure uses a central core, known as inner tube, which usually holds stairs, lifts and installations, and a perimeter of columns around it, which form the exterior tube. The interior tube is tipically more massive (often made of reinforced concrete), and the exterior tube is "lighter" (made of steel or concrete columns). Both tubes are conencted via horizontal elements which make up the floors and also transmit any horizontal froces from the facade to the core.

The facade of the building is load bearing. This is a direct consequence of the integration of the exterior "tube" into the facade, something which most framed tube-in-tube buildings do in order to liberate the interior space from structural elements and achieve a more flexible interior.

So the facade of the builing is techinically load-bearing, yes, however, in between the load-bearing colums we find a curtain-wall type of facade, which by itself would not be cosnidered load-bearing.

From an aesthetic point of view, the facade features a curtain wall with white metal piers between the windows and white details covering each slab. Each pier acts as an exaggerated mullion between the windows, and consists of a pair of round semi-cylinders separated by a tapered rectangular fin. These nearly sculptural piers manipulate the changing light throughout the day.

The windows are made up of two panes, a fixed one that acts as a spandrel with a larger one above it, both made of transparent glass.

The two facades parallel to 8th street are straight, while the ones parallel to Figueroa street are curved.

Another material found at the 777 Tower is italian marble, used in the three-story lobby.
