Inge Onsea and Esfan Eghtessadi, the couple behind the fashion brand Essential Antwerp, hired designer Gert Voorjans to revamp a former French consulate into their family home in Antwerp. A sculpture of an archer by Herbert Ward stands at one end of the pool.

A large Sterling Ruby painting provides a striking contrast with panels of Tassinari & Chatel chartreuse damask in the salon, where velvet-clad 19th-century Italian sofas are joined by a green settee from the original Concorde waiting lounge. The mirror is French neo-Renaissance, the lapis lazuli–color Lunéville dogs are antique, and the Aubusson carpet is from the 1930s.

Voorjans opened up a columned doorway, flanked by a David Salle grisaille painting and a Jean Dubuffet painted sculpture; it connects the stair hall to a salon.

Lush plantings and mirror-paneled walls lend an exotic air to the dining room; the Napoleon III chairs are finished in black lacquer, and the floor is inlaid with rectilinear patterns of glossy dark rosewood.

Walls of Indian palisander line the library, where a work by Jean Dubuffet is installed over the Rosso Levanto marble fireplace. A 19th-century ajouré metalwork lantern from India hangs above a claw-foot antique sofa, a Napoleon III chair in tufted Moroccan leather, and an 18th-century Tuscan floor cushion.

The master bath features a shower and tub lined in Arabescato marble with fittings by Lefroy Brooks.
