Selfridges Department Store, Birmingham, England


The Birmingham branch of Selfridges is a billowy mattress of a building, clad in 15,000 shimmery aluminum discs like that famous Paco Rabanne dress. It was designed by Future Systems—the name tells you pretty much everything you need to know about the firm—to be a landmark and a catalyst for the revitalization of a largely moribund city center. “An ersatz urban cliff, a giant sea anemone, a friendly, blob-like alien, the mother of all magic mushrooms,” wrote Guardian architecture critic Jonathan Glancey. “This is the department store as unalloyed architectural entertainment.”

The Winchester Mystery House
San Jose, Calif.

Background: Work on this home began in 1884 and lasted through 1922, when owner and designer Sarah Winchester, heiress of the Winchester rifle company, died. At one point, the property sprawled over 161 acres, but has since been reduced to just 4 acres.

Why it’s unique: Winchester was never a huge fan of blueprints. Instead, she preferred an on-the-fly design strategy, sketching rooms and architectural oddities whenever inspiration struck. Notable features include 40 bedrooms, three elevators, 47 fireplaces, 17 chimneys and 467 doorways. The house originally had seven levels, but an earthquake in 1906 collapsed three of them. Tourists now flock to the house to see its many quirks, including a staircase that leads straight to the ceiling.
