"As the name suggests, the heart of this sprawling, two-story bookshop is architecture, with a vast selection of fine art, design, and décor titles thrown in for good measure. William Stout, who’s an architect by trade, began his vast collection 30 years ago and has since grown it to include close to 20,000 titles. In fact, we tapped him to curate a collection of books for our San Francisco goop MRKT, fittingly set up in the Frank Lloyd Wright building."
