When Sanderson built 19 Wells Street in 1929 to house their design studios, offices and showroom, it was a beacon of modernity. This is where those iconic floral wallpapers were hand-drawn, in a building designed to inspire. And in the late 1960s, it was the headquarters for Columbia Pictures. Today, it’s been gloriously restored by architects TateHindle and interior designers Universal Design Studio to retain all its period charm – from the magnificent Art Deco staircase in the lobby to full-height Crittall windows that flood every floor with natural daylight. And atop its distinctive copper dome lies a shared roof terrace with panoramic views and a covered kitchen.
