URBAN - Stair of the Week: A spiral in Copenhagen

In most office buildings, stairs are required fire exits and little more, often alarmed so that even if you want to use them, you can't. I have noted before that if stairs were designed with more care and flair, then people wouldn't take the elevators and escalators so much, saving energy and making people healthier. Mayor Bloomberg of New York has recently joined the party, with his Center for Active Design, promoting " greater physical movement within buildings for users and visitors."
