Known for its rainbow crosswalks and two-for-one drink specials, the Castro isn't exactly a bastion of peace and quiet. Nor is it where you'd expect to find a barn, once built for horse-drawn delivery service, converted into a modern home-slash-hideaway. But then, in the Castro, anything goes.

In the hands of architect Joel Karr, this Douglass Street house, just a few blocks off the main drag of 18th Street, is now a one-of-a-kind home that makes use of all the original quirks: There are vaulted ceilings, triangular closets, and even a great room with French casement windows and skylights across a steepled ceiling.

You'll enter to a foyer and quiet sitting area with a garage-door design that has postmodern industrial vibes—and a breeze from the outdoors. The rest of the street level is dedicated to the master suite, which is large enough not to sweat a king-sized bed and a plush reading nook. If that's not enough space, the sitting room opens up, by way of French doors, to a charming patio (save your roosters for your country home).

Up the stairs, two additional bedrooms are ready for guests, who will have easy access to raid your fridge: The second story is home to the modern kitchen and dining room, as well as a comfy living room, with radiant floor heating throughout.
