A Tara Donovan wall sculpture strikes a playful note in the living room of a Southampton home designed by Ferguson & Shamamian Architects. Interior designer Victoria Hagan grouped a custom-made two-tone sofa with pairs of Jean de Merry armchairs. The chandelier is by Jonathan Browning Studios. 

Above the living room fireplace, a painting by Günther Förg overlooks a seating area with a custom-made sofa in an ALT for Living fabric, Forest & Giaconia chairs in a Kravet fabric, and a Paul Mathieu table from Ralph Pucci. The floor lamp is a collaboration between ceramist Peter Lane and Chahan Design.

In the dining room, a Hudson Furniture lighting fixture hangs over the Victoria Hagan Collections table and Poltrona Frau chairs, while a Liaigre sconce surmounts a Cocobolo sideboard. The sculpture of colorful orbs is by Annie Morris, and a Tinatin Kilaberidze bench from Valerie Goodman Gallery sits beneath a multipart work by Song Dong.

A pair of canvases by Marina Perez Simão and a digital work by teamLab preside over the bar area.

India Mahdavi rattan chairs from Ralph Pucci join Robert Guillerme side tables from Eric Appel in the solarium, whose doors open to gardens masterminded by Hollander Design. The ceiling fixture is by Hubbardton Forge. 

Whimsical works by Niki de Saint Phalle pop against walls painted a Benjamin Moore red in a bedroom furnished with a Jean-Pierre Tortil chair and ottoman as well as a Victoria Hagan Collections chest of drawers. The curtain fabric is by John Rosselli & Associates, and the rug is by Tibetano. 

An abstract wallpaper by Fromental animates a bath outfitted with a Stephen Antonson mirror from Liz O’Brien, Roll & Hill sconces, and a stone-top vanity  with Dornbracht sink fittings.

In a guest room, a Donald Sultan artwork and curtains with fabric from Studio Four NYC make a verdant splash, as does the Romo fabric on a Holly Hunt chair pulled up to the Suite NY desk designed by Bodil Kjær; the chandelier is by Jonathan Browning Studios, the bed and linens are by Matouk, the bench is by Liaigre, and the rug is by Marc Phillips.
