Ending months of anticipation, rock-star Danish architecture firm Bjarke Ingels Group (BIG) revealed details of a massive residential complex in New York City yesterday. W57 -- named for the street on the Hudson River where the 600-unit structure is planned -- will be a striking addition to Manhattan’s skyline when it rises in 2015. Short in stature (in some places, anyway), but towering in ambition, it purports to do something never before done in New York: Mate the American skyscraper and the European perimeter block to spawn a freak, architectural love child.

Hang Around is one of those ridiculously obvious designs that makes you smack your forehead and say: How on earth didn't someone think of this earlier? Designed by the Danish creative powerhouse KiBiSi, Hang Around is a flat wooden stirring spoon with a little notch in the handle. Hook the notch onto the rim of your pot, and the spoon balances perfectly in mid-air, which means, of course, that it's not spreading spaghetti sauce all over your counter. Brillz!

Just when you thought Bjarke Ingels had conquered every last corner of his native Copenhagen, the 36-year-old starchitect has gone and unveiled plans for yet another building on home turf, this one even wilder than the last: It’s an energy plant that doubles as a downhill ski resort.

A sofa, at its most primitive, is nothing but a pile of pillows. And if you replace the pillows with cushions that look like sandbags? You might get something like the Brick sofa -- which evokes a a makeshift flood wall, a soldier's foxhole, or a survivalist bunker. It's the latest work from KiBiSi, the Danish product-design powerhouse co-helmed by the architect Bjarke Ingels, a 2010 Master of Design.

"Sustainability is often misunderstood as the neo-Protestant notion "that it has to hurt in order to be good," says Danish architect Bjarke Ingels. His goal in designing the Danish World Expo Pavilion: to show that a sustainable lifestyle can be fun.
