SF Store Add-On? [Updated]

The evidence is was contradictory about whether Apple is adding on to the San Francisco (N. Calif.) retail store. Major construction is underway at 24 Ellis Street, directly behind the existing store, on a single-story, 12,000 square-foot building with a peaked roof. A 4-story building occupied the space around the time the Apple store was built, but it was subsequently demolished. The new structural steel façade framework is the same height as the adjacent Apple store, but other architectural details don’t match, and there is an “Available” sign from the leasing company out front. City permit records don’t reveal who the future occupant might be. Yet, the 12-foot barricade fronting the site is plastered with iPod posters, DPR Construction Inc. (Apple’s favorite) trucks are parked in the adjacent parking structure, and one insider says, “Yes.” Perhaps it will turn into a speciality store for Apple, focusing on music, iPods and TV. [Update: No Apple store. The real estate broker says it will be a clothing boutique.]
