If you’ve visited the Brant Foundation in lower Manhattan, chances are you noticed the dramatic slice through the historic building’s fourth-floor ceiling. The striking skylight—created by New York–based Gluckman Tang Architects—doubles as a water feature on the roof of the former power substation. “Introducing natural light in an unexpected way brings joy; it makes you feel good,” explains Dana Tang. “That’s what we’re after, whether it’s a place for viewing art, a spa, or a residence.” In 25 years of working together, she and Richard Gluckman have turned their hands to all of the above. Those same good vibes can be found at their Mii amo spa in Sedona, Arizona, a complex of stucco and fired-adobe structures set among red rock formations in Boynton Canyon, as well as a modern guesthouse in La Jolla, California. “It’s important that a building reflect the nature of the place,” says Gluckman. The same will most certainly hold true for their next big project: a master plan for a new Georgia O’Keeffe Museum in Santa Fe. New York ; gluckmantangom
