Danish architects and designers Bjarke Ingels Group have unveiled their design for a tower in Prague, Czech Republic.

The building will be a combination of office and residential spaces.

“What will appear as four different towers is actually one continuous building that is sliced up and pulled apart to maximize the amount of surface and facade area to create attractive apartments,” say the architects.

Combining the tradition of building towers in clusters with the coldly rational American skyscraper, apparently you wind up with a tower that has been cut, twirled and splayed apart, resulting in a giant undulating W that's a single.
