A new monograph celebrates the work of interior designer Timothy Whealon, who is best known for elegant rooms that are a mix of classic and modern elements. In Pursuit of Beauty: The Interiors of Timothy Whealon (Rizzoli, $50) was cowritten by Whealon and journalist Dan Shaw.

True to Whealon’s signature style, this entrance hall features a combination of contemporary (the side table and mirror) and traditional (the sconces and moldings).

In the dining room of a New York City townhouse, Whealon employed an antique Swedish painted Rococo chair and a 1940s gilt-metal sconce, which are set against lively seafoam-green walls.

The guest room of this London townhouse features camel hair walls and a French Directoire campaign bed with a canopy. The bedcover is an antique Persian textile.

Inside a Sutton Place townhouse in New York City, Whealon combined a cut-glass, hexagonal lantern from northern Europe with a Regency Pollard oak library table.

This penthouse in Manhattan’s Gramercy Park was outfitted in a soothing mix of grays and greens.
