Just when it seems the whole world is going underground, a Tudor Revival home has hit the market in Burlingame complete with oak trees on the meandering grounds, a swimming pool, and interior stone cave, you know, for really hunkering down.

Built in 1937 on just shy of an acre, the nearly 6,000-square-foot castle (yeah, we're calling it a castle) doesn't have a moat, but it's built to last with a steeply pitched and gabled roof, stone walls on the first floor, plenty of intricate wrought-iron hardware, and quirky faux timber beams.

It's once you step through the arched front door and past the foyer when things start to get, you know, kind of weird. The living room has wood beams mimicking trees that spiral up walls of glass featuring quite lovely views, and the high pitched ceiling holds a chandelier at the center. But what really catches the eye is what appears to be a stone cave. Inside the house. Duck and follow the way into a fully stone-clad sitting room with a fireplace—cuz you know, a stone room might get chilly in winter. We don't know if it's doomsday proof, but it looks safer than your average SF apartment.

But anyway, we digress.

There are four distinct bedrooms here, some with coved ceilings and retro baths. There's also a forming dining area fit for royals and a chef's kitchen with a breakfast nook that transitions into another sitting area overlooking the backyard.

Also on the property is a studio above the two-car garage with a living area and fireplace, sleeping quarters, and kitchen that opens to a private deck. There's even a loft to use as a project space or extra sleeping nook. Rounding out the storybook retreat is a pool and jacuzzi.
