Grand great room interior design in a Mill Neck estate by Robyn Baumgarten

Robyn Baumgarten has designed Long Island homes for more than 25 years, and her work fits right in among Mill Neck's estates. Her rooms have appeared in House, Distinction, Fashion Manuscript, Newsday, and the Long Island Press. She runs her studio in Plainview.

Mill Neck is a tiny, private village on the water. Tudor, Georgian, and Colonial Revival estates sit on wooded, multi-acre lots above Mill Neck Bay. Robyn designs rooms that match their scale and their history.

She works quietly and brings rare resources. Through a network of more than 150 trade vendors, Robyn finds custom pieces, art, and materials you will not see anywhere else.

Why Mill Neck Homeowners Choose Us

Luxury Estate Design,
Handled With Care

Mill Neck families value privacy. Robyn respects that. She keeps your project quiet and works on your schedule, with a small, trusted team.

These are landmark homes, some nearly a century old. Robyn protects the Tudor woodwork, the plaster, and the stone, then adds comfort and modern systems where they belong.

On the water, light and view lead the design. Robyn orients rooms toward Mill Neck Bay and adds glass that frames it, so the setting becomes part of the home.
