The welcoming family room of this North Shore home designed by Michelle Williams invites lounging on custom Barclay Butera sofas, which are covered in dark gray Brentano and light gray Pollack fabrics, and chairs, also by Barclay Butera, featuring an Osborne & Little textile. A mix of patterns, materials and accessories—including barrel lids repurposed as art from Accessory Preview in Los Angeles—adds both interest and warmth.
