One of today’s most celebrated and influential design firms creates eclectic, inspired, and quietly virtuosic interiors across the style spectrum—from bohemian glamour to country charm, sophisticated modern, and historically informed—for clients as individual in taste as Anna Wintour and Jessica Chastain.

Here the Carriers showcase homes that express their clients’ personalities and dreams, through the practical filters of lifestyle and place—and reveal the design principles behind them. Their range spans a historic, art-filled New York duplex, replete with period vestiges, to an updated Mediterranean-style Southern California house with an art deco–era core, and a refreshed Connecticut lakeside retreat with glass expanses that capture the views.
