If you are even a casual appreciator of art in New York, the chances are that you have stepped into one of Annabelle Selldorf’s spaces, and been entranced. Perhaps the most coveted architect among the minimalistically inclined art elite, Selldorf has designed a broad spectrum of the city’s art sites, from theNeue Galerie uptown, steeped in Old World splendor, to the galleries of blue-chip titans like David Zwirner and Hauser & Wirth, where her tautly balanced settings at once put the viewer at ease while calling them to attention. Her buildings are special places, where one wants to return.
