In the living room of a London residence that David Kleinberg Design Associates renovated in collaboration with architecture firm Donald Insall Associates, artworks by Sterling Ruby (left) and Tadaaki Kuwayama frame the view into the library where a mirror by Sam Orlando Miller is mounted above an antique mantelpiece.

Windows in the library overlooking Eaton Square are curtained in a custom-embroidered Holland & Sherry fabric. The room features an ebonized-wood desk by Object Studio topped by a Paavo Tynell lamp.

A chandelier by Régis Botta for Ozone hangs above the sitting area, where Kleinberg designed the sofa and armchair, both covered in a Pierre Frey fabric; the mahogany cocktail table; and the daybed. Joining the mix are pinkish crystal-resin drum tables by Atta and a custom rug by Edward Fields.

In the dining area near the open kitchen, Kleinberg installed a pair of custom pedestal tables and lacquered mahogany chairs beneath a pendant by Michael Anastassiades.

A vintage Italian chandelier spirals above the primary bedroom’s bespoke parchment-clad bed.

In a marble-lined powder room, custom sconces by Jonathan Browning from the Bright Group illuminate the custom-made vanity with Lefroy Brooks sink fixtures.
