[Screenshot | click image to view commercial]
Digging around the internet with keyword searches "bookstore", "tree", "car commercial", and combinations of those and other words, I could not find the store. But then I considered that most likely a commercial would be shot in Los Angeles, then Hennessey + Ingels came to mind. I'd visited their Santa Monica store many years ago, and even though they no longer have that store on the 3rd Street Promenade (they moved to nearby Wilshire Blvd.)
Update/Correction: As Quixote's comment indicates, I was wrong, wrong, wrong. The store is not Hennessey + Ingels, it's Skylight Books on Vermont Ave. also in LA. Below is a photograph comparing H+I and Skylight Books:

The reason for my confusion is evident, given the ceilings' shapes and materials, but the diagonal articulation of the wood members is clearly not happening at H+I, only at Skylight. Not sure how I'd think straight members are the same. Nevertheless, thanks to Quixote for fixing my error.
