Églomisé panels—conceived by the designer and executed by New York artist Miriam Ellner—lend a lustrous finish to the fireplace that separates the family and living rooms. Simon also designed the armchairs, which are covered in strié velvet from Zimmer + Rohde, and the sofas sporting two different Romo fabrics. The fireplace screen and lamps are from Holly Hunt in New York, and the carpet is by Stark.
