PREVIEW I don't know whether this is awesome or boring, but one of the most perverse pleasures to be had in the Bay for the last decade has been fantasy house-hunting — dressing like you can afford more than a rent-controlled railroad flat's closet and hitting the Sunday open-house real estate orgy circuit, mostly to decry the recent penchant for tacky recessed lighting and cheap beige granite counter-tops. The '80s are back! If you're a premium architecture and design junkie, though, you'll be swooning all September — launching your intellectual and tactical fantasies into the clouds with the Architecture and the City festival, presented by AIA San Francisco. The sixth annual celebration of unique builds, the nation's largest, not only takes you on the San Francisco Living: Home Tours drool-a-thon (Sept. 12-13) focusing on smart sustainability, but also explores a bonanza of exciting, dialogue-stimuutf8g Bay design ideas through presentations, investigations, demonstrations, and more. Prepare to push up your teeny octagon-shaped eyeglasses and scream, "Build it! Build it NOW!"

ARCHITECTURE AND THE CITY Through September 30. Check Web site for locations, times, and prices. www.aiasf.org/archandcity
