The corridor beyond leads to the bedrooms. The primary living area of the house is clad in glass walls that look onto Lily Pond.
Designer Pol Theis stands in the entry to his modernist Sag Harbor getaway. The wall behind him is covered in one of his firm’s limited-edition photo-based wallpaper designs, this one a negative image of a mathematician’s notebook that mimics the look of a chalkboard.
Theis designed the lounge furniture in the living room and collaborated with Alex Randall on the ceiling fixture that gives the home its name: 31 Pigeons.
The adjacent dining area seats 14 on classic metal bistro chairs with seat cushions covered in an Osborne & Little fabric; the table is from Jayson Home. The high-gloss black subway tiles are from Waterworks.
Theis made room for a small walnut-paneled study with an adjacent wine cellar and humidor. The Napoleon III tufted chaise is covered in a Designers Guild fabric.
A narrow courtyard between the public and private spaces contains a vintage factory table and an herb garden.
The tubs and showers in all the bathrooms are sunken into the floor; the Andy Warhol portrait is by Philippe Halsman.
Theis designed the headboard in the master bedroom; a walk-in closet lies behind the dark partition wall. The burlap on the canopy chair is from Anne Becker in Paris; the safari photograph is from Jayson Home. Alex Randall designed the squirrel sconces.
Theis can dive directly from his bedroom into the saltwater lap pool below.
