The electronics giant that is seemingly obsessed with glass has staked another claim in the architectural world.

Apple, the Cupertino, Calif.-based company, was awarded a design patent by the U.S. Patent and Trademark Office at the end of last month for its upcoming glass-clad, two-story flagship store in San Francisco.

The patent only shows drawings of the “ornamental design” of the structure, but according to San Francisco real estate site SocketSite.com, the building’s façade will feature two 23-feet-wide by 44.5-feet-tall sliding glass doors, which will allow the store to be opened up to the street. SocketSite reports that when the doors are closed, “the columns of the steel framed doors would divide the façade into four discrete glass bays of 23 to 31 feet each.”

The project was initially proposed in 2013 but saw a few delays before being approved last March. It is now under construction.

A portion of a filing with the San Francisco Planning Department regarding the project reads: “Full‐height, powder‐coated steel framing members will separate the large butt‐glazed glass panels into six bays at the Post Street (front) façade. The center bays of the facade will be operable so they will slide open to create a full‐height opening at the center of the facade.”

James O’Callaghan of the structural and façade engineering firm Eckersley O’Callaghan is the first of 13 “inventors” named on the patent. Eckersley O’Callaghan has had its hand in the design and engineering of many of Apple’s architectural glass structures.

In August Apple was awarded a patent for its well-known glass cube building design, as featured at its flagship Manhattan store. That design—a 32-foot-tall structure—consists of 15 lites of glass. The late Steve Jobs, founder of Apple, is listed as one of the inventors in that patent and reportedly paid for—and owned—the structure itself.

The company’s two most recent glass building design patents come roughly a year after the company was awarded a patent on the glass staircase design used in its stores. Apple also has an architectural patent on a glass cylinder design for its flagship Shanghai store.
