Tiffany continued to work on residential, public, and ecclesiastical interiors to a far greater extent than many have assumed. One of the most remarkable commissions was for the home of two of his most important patrons, Louisine and Henry Osborne Havemeyer. Their house at 1 East Sixty-sixth Street, completed in 1892, was replete with glowing iridescent glass-mosaic walls, lighting fixtures of Near Eastern derivation, elaborate filigreed balustrades and fireplace screens, and a dramatic suspended staircase. Tiffany was responsible for every decorative element, enhancing the unified effect. His artisans and designers mastered the techniques needed to produce and decorate objects in metal, wood, glass, fabric, and wallpaper and became manufacturers of rugs, glass mosaics, lighting fixtures, and ornamental cast bronzes.
