Furniture from Espasso animates an area that opens to the newly landscaped garden.

Bryan O’Sullivan salvaged limestone for the hallways and parquet de Versaille flooring for other interior rooms.

Karen Swami vases are displayed on a Faye Toogood table in the grand salon. The artwork on the left is by Abigail O’Brien, the sofas are by Pierre Paulin, the armchairs are by Stephane Parmentier, and the chandelier is from Fortuny.

Photographs by Abigail O’Brien flank an archway in the grand salon that features custom gilding by Ateliers Gohard.

“The main bath was complex,” says O’Sullivan who relied on Irish firm Miller Brothers to execute the room’s exceptional marble design.

While the home’s kitchen was all new, much of the home’s interior had been stuck in the 80s requiring a total overhaul to restore it to its original grandeur.

The Alberto Giacometti-inspired dining room features a grisaille wallpaper by Zuber, leather-and-wool rug by Toyine Sellers, and custom seating by British furniture maker Jonathan Sainsbury.
