The Manhattan offices of AD100 designer William Sofield are a calculated seduction, a deep immersion in le style Sofield, with all its arcane historical allusions, eccentric details, unexpected material juxtapositions, and spellbinding beauty. Part workspace and part Wunderkammer, the expansive loft is chockablock with art, furniture, and curiosities, all tracing Sofield’s peregrinations through the worlds of architecture and design over the past quarter century. It’s no wonder that tastemakers on the order of Tom Ford and Richard Buckley, artists Brice and Helen Marden, Ralph and Ricky Lauren, and Mary-Kate Olsen and Olivier Sarkozy have called on Sofield to help forge their particular visions of domestic bliss.
