Margarita McGrath and Scott Oliver of noroof Architects specialize in small-space design, perfect for their headquarters--and many clients--based in New York City. We featured their innovative renovation of an under-700-square-foot apartment (for a family of four!) in our June 2009 Think Smaller issue.

Favorite room in the house: "The 'cat-bird seat.' The cats like to sit on the windows and watch the birds. I like to watch the street and what's going on, read, open the window to get fresh air."

Most recent purchase: "We're spending all our money on computers for the office."

Currently longing for: "An iPhone or a Bambi Airstream."
