Step Inside a Casually Eclectic Home in Southampton

The two original wings of the L-shaped carriage house have been bridged with a newer, stone-walled dining room, which complements a series of parterred stone steps that lead to the swimming pool.

Homeowner and decorator Deborah Heimowitz displays artifacts from her travels on shelves in a corner of the living room. The Christian Tortu bamboo planter is from Pennington Flowers.

In the entry, a bench from ABC Carpet & Home and accent pillows from John Robshaw beckon. The eroded teak cuttings are from Andrianna Shamaris.

French doors lead from the living room to a patio. The sofa, by Barbara Barry for Baker, is covered in a Nobilis fabric.

The ceiling fixture and chairs in the dining room are from Holly Hunt.

Grass-cloth walls in the master bedroom emphasize the house’s stunning architecture. The headboard is from John Robshaw; the batik throw is from Andrianna Shamaris.

A brick-lined approach leads to both the former carriage house’s new front entry.

The patio includes sofas from Jardin de Ville and a fire pit coffee table from Restoration Hardware. The locust-post canopy is from Marders.

Teak chairs from Homenature and chaise longues from Sutherland are arranged around the pool area.
