Space in New York City is at a premium—even rooftop real estate is a coveted amenity. When a client of architect Robert Kahn asked for ideas on developing the rooftop of his Lower East Side duplex, Kahn (a member of the Remodelista Architect/Designer Directory) suggested an observation deck whose shape would pay homage to the iconic water towers that mark the cityscape. The client initially dismissed this idea (too impractical), but the concept eventually captured his imagination (and now his roof is a fixture of the downtown New York skyline).
