Luxury Interior Designer on Long Island, NY
Interior design for Smithtown's antique colonials, farmhouses, mid-century homes, and modern customs along the Nissequogue River.
Robyn Baumgarten has designed Long Island homes for more than 25 years, and Smithtown is one of her favorite places to work. Her rooms have appeared in House, Distinction, Fashion Manuscript, Newsday, and the Long Island Press. She runs her studio in Plainview and travels east to the North Shore.
Smithtown has homes from almost every era. Antique colonials and farmhouses sit near mid-century splits and brand-new customs. Robyn designs for all of them, and she respects what makes each one special.
She also brings in pieces you will not find in stores. Through a network of more than 150 trade vendors, Robyn sources furniture, fabric, and lighting for each home.
Some Smithtown homes are hundreds of years old. Robyn treats that history with care. She keeps the wide-plank floors, old beams, and trim that tell the home's story.
Then she makes the house easy to live in. New wiring, better insulation, and a smart layout hide behind the old-world charm. You get the best of both.
Robyn guides the whole project. She works with the right trades for older homes, holds the schedule, and checks each detail, so nothing gets lost along the way.
From an antique colonial to a modern custom, here is how Robyn helps Smithtown homeowners. Click any service to learn more.
