In the living room, whose walls are finished in a peachy-pink plaster, Graybill grouped custom sofas clad in de Le Cuona linen with a vintage Osvaldo Borsani armchair, an Edward Wormley cocktail table, and a Vienna Secession side table. The pendants are by Roman and Williams Guild, and fireplace is by Jamb.

Vienna Secession café tables and Poul Henningsen chairs join a custom-made banquette in the drawing room of designer Bryan Graybill and attorney Daniel Dokos’s East Hampton home, which they built with the architectural firm Historical Concepts; Michael Anastassiades sconces are mounted between the windows, and the portrait was painted by Paulus Franciscus Kromjong.

Graybill devised the Viennese-style bench that wraps around the entry hall’s Jamb fireplace, beneath a George Condo painting. For details see Sources.

The parlor walls, lacquered in a Fine Paints of Europe custom color, provide a glossy backdrop for artworks by Georges-Lucien Guyot and a Thomas Lavin sofa beneath a Tommaso Barbi leaf chandelier.

In the kitchen, which Graybill dubbed the Orangerie, copper lights sourced from the Brimfield flea market are installed above a bronze-top island crafted by Timeless Homes; the built-in refrigerator is by Sub-Zero, and the sink fixtures are by Waterworks.

A work by Janet Liebowitz hangs in the master bedroom, where vintage lamps by Roger Rougier flank the custom bed by Graybill; the pillows and curtains are by de Le Cuona.

A work by George Condo hangs next to the doorway leading to the master suite’s dressing room, which is painted in Sierra, a pink by Fine Paints of Europe.

The master bath features a vintage Europhane ceiling light, Woka Lamps Vienna sconces, and a Catchpole & Rye tub outfitted with Waterworks fixtures; the floor is by ABC Stone.
