In the sunlit living room of this weekend home, de Gournay Chatsworth wall­paper delivers springlike blooms year-round; the banquette is upholstered in a tweed and the tufted sofa is in a velvet, both by Clarence House. “It’s a room where the kids can curl up on the banquette, or grown-ups can enjoy a drink before dinner,” Whittaker says.

On a skirted table in a corner of the living room, a Chris­topher Spitzmiller lamp — with a Bunny Williams Home shade — is in a deep blue that matches the lacquer of the library next door. The Leora Armstrong artwork is from Gerald Bland.

In the breakfast room, a punchy lantern from the Urban Electric Co. picks up the crimson tones in the floral Brunschwig & Fils linen on the backs of the Oly chairs. The baby blue of Quadrille’s treillage-patterned wallpaper coordinates with the Kravet faux leather used to upholster the chair seats.

The master bedroom is its own oasis, with walls in Clarence House Arbre de Vie wall­paper.
