Indulge your voyeuristic tendencies at Then and Now: Houston Heights Association's 2013 Spring Home & Garden Tour. Six notable Heights-area homes are open for public display and scrutiny, inside and out. ''All of the houses are special,'' diplomatically insists HHA tour representative Janet Buchheit, but she admits that one particular house stands out. Karen and Robert Derr's home at 2310 Rutland was built in 1969 and operated as the Courtesy Washateria, Buchheit explains. The one-story cinderblock home maintains its trendy original metal frame ceiling, concrete floors, and commercial windows and doors, and features an open living/dining/kitchen area. Quirking up the concept even further, a ''WashDERRteria'' exterior mural depicts the couple as stick figures, riding on the Fat Boy atomic bomb — à la DocDERR Strangelove.
On Friday, there's a Candlelight Dinner & Auction along with a preview tour. On Saturday, the tour runs noon to 6 p.m. For information, call 713-861-4002 or visit houstonheights.org. $5 to $25.
