Interior designer Timothy Corrigan transformed a neoclassical château in France’s Loire Valley into his own home away from home. A Régence commode and Louis XIV armchair grace the master bedroom.

A sofa and chairs upholstered in red velvet enrich a sitting area.

Traditional furnishings play off modern art in a living room.

Banquette seating adds a clubby air to a bar.

While remodeling a 1930s home in Lake Forest, Illinois, Corrigan converted the greenhouse into a pool cabana, furnished with linen sofas and wicker chairs.

The kitchen features a spacious island and ample cabinetry.

Corrigan designed the dining room’s bookcases; the works over the mantel are by Jasper Johns.

The master bedroom is painted in two shades of white; a work by Robert Rauschenberg hangs beside the bed.

The family room of Corrigan’s own Los Angeles home is furnished with a pair of vintage chairs by T. H. Robsjohn-Gibbings (left) and a second pair, in green, by André Arbus.

In the dining room, a Baroque-style waxed-oak table is surrounded by vivid green silk wall panels under a gold-leaf ceiling.

The 18th-century portrait in the master bedroom’s reading area is of a family ancestor.
