Welcome to the fifth in a series of 3-D explorable tours of historic Los Angeles spaces, created by Craig Sauer using cutting-edge Matterport technology. And what cooler space to explore than the lobby of the newly rebranded CalEdison, an Art Deco masterpiece that was L.A.’s first air conditioned, seismically safe tower?

You might know the building as One Bunker Hill, a name given it in 1972, when Edison moved its offices to Rosemead and sold its namesake tower. Hopes were still high that the Bunker Hill Redevelopment Plan would yield a thriving, live-work community where young professionals contributed to the tax base 24/7.

It didn’t exactly work out that way—a heartbreaking tale of scorched earth public policy hubris documented in Gordon Pattison’s family story and on the On Bunker Hill blog— but in seeking to make the aging, low rent building more appealing to new tenants like the US Postal Service, ceilings were dropped, old fashioned spaces reconfigured, and the long, open patios enclosed with glass. And so it remained, for four decades.

Today, under new, preservation-focused owners Rising Realty Partners, these insensitive upper floor additions are being peeled away and the building marketed to creative tenants who appreciate its machine age aesthetics and are keen on downtown. It only took two generations!

But the grand T-shaped lobby was never “updated,” and it’s this extraordinary space you can explore through Craig Sauer’s 3-D photography.

But first, a little history: In 1931, Southern California Edison’s opulent Art Deco corporate headquarters was erected at the foot of Bunker Hill, on a prime 175’ x 175’ corner site kitty corner to the Biltmore Hotel (Schultze and Weaver, 1923) and opposite Central Library (Bertram Grosvenor Goodhue, 1926).

Architects Allison and Allison designed the 12-story height limit tower with its bold, geometric stepped facade and cutting edge mechanical innovations. P.J. Walker Co. built it. Constructed at a cost of $2,500,000 and boasting 250,000 square feet of office space, its all-steel frame was meant to withstand fire, hurricane force winds or the most powerful recorded earthquakes. And when the devastating 6.4 Long Beach temblor struck on March 10, 1933, the Edison Building just shrugged.

That unshakable frame was beautifully wrapped in sober granite and terracotta facing, with a rainbow of stone finishes within. The exterior rotunda’s relief sculptures representing the “Generation,” “Distribution” and “Utilization” of electricity are by Merrell Gage. The central lobby mural, “Power,” is by Hugo Ballin, with Conrad Buff and Barse Miller gracefully handling the narrow frieze paintings above the elevators, also on an electrical theme.

As befit a tower housing a modern electrical utility, the ventilation systems were powered, with windows that opened and closed automatically to control internal temperature. And today, the building is newly LEED certified. Also, fans of Los Angeles literature will note that the prime corner site was declared John Fante Square a few years back (reader, we nominated it).

But enough background: the lovely lobby awaits your exploration. Click here to begin.
