San Francisco, CA





221 Main Street

The neighborhood around 221 Main Street in the heart of San Francisco is rapidly evolving with an influx of technology companies along the Spear Street Corridor. Beacon Capital Partners wanted to update 221 Main, constructed in 1974, and establish the building as an anchor for the growing area.

For this project, DetaiLED® worked with ESI Design to create a 126 foot-long, 25-foot wide, digital display that extends from the exterior façade to the interior lobby. This integrated element renews the building with a modern design while complimenting its angular form. The artistic installation blends three different LED resolutions into a single display. Etched diffusion glass mounted atop the LED panels outside spread the light across the entire surface, creating a seamless image.

An address that once lacked a distinguishing trait now has a distinct presence that speaks to the promising future of the neighborhood. During Beacon’s ownership of the building from 2011 to 2014, it leased nearly 130,000 square feet at strong rental rates. Current owner Columbia Property Trust pushed occupancy to 98%, including tenants DocuSign, Tradeshift and Prosper Marketplace.
