In the sun room, a Lillian August settee, paired with pillows in Morris & Co., Jim Thompson and Kirsten Hecktermann textiles, sidles up to a jaunty coffee table ottoman from Hammertown Barn Country Store in Pine Plains. Between a pair of petite RH club chairs rests a set of kidney-shaped midcentury walnut nesting tables from 1stdibs. Bamboo blinds by Rita Konig for Joss Graham filter sunlight without obscuring the view.
