Round bedroom and secret space highlight Tenderloin TIC

Rare is the day when we see a San Francisco home with both a circular bedroom and a secret space. Well, today is that a day. Normally such design details would be found inside manors or mansions, but these elements can be found inside a tiny, circa-1922 tenancy-in-common smack dab in the Tenderloin.

French doors lead into the oval bedroom, which features period accents on the walls and windows. The living room boasts built-in cabinetry including a bookshelf on a pivot hinge. Closed, it appears like a regular set of shallow shelves. A gentle push on the edge swings it open to reveal what the listing calls storage. But a more creative use can be made of such a cool, secret space.

Featuring one bed, one bath, and 835 square feet, 735 Geary #504 is a top-floor unit that comes with crown moldings, hardwood floors, bathroom with glassed-in shower, and in-unit washer and dryer.

For lack of a better cliche, they don’t make them like this anymore—a great example of the Tenderloin’s distinguished past.

HOAs are $425/month. Asking is $669,000.
