A private oasis awaits in this historically significant 6 acre mini estate with striking additions and landscape by renowned mid century architect Philip Johnson of Glass House fame...an offering that rarely becomes available. The home and barn were built in the 18th century, additions and modernization were completed in the 1920's and 30's, but the monumental changes were made by previous owners, Burton Tremaine and Emily Hall Tremaine in the 1950's. As one of the largest collectors of American contemporary art of their time, the Tremaine's commissioned Philip Johnson to expand and reimagine the property for art display and entertaining. The result is a work of art in itself! The main residence is 3145 sq. ft., features 4 bedrooms, 3.5 baths, formal dining room with fireplace, great room with gas fireplace and wide plank flooring that connects two glass pavilions. New furnace, oil tank and hot water storage tank (2022) plus home generator. Guest cottage provides 2 bdrms and 2 baths and connects to barn converted to great room with 2 fireplaces and walls of glass to courtyard. Exquisite pool, outdoor kitchen, stone walls on picturesque large level yard. A separate building previously used as an office is ideal for gym, yoga, art/dance studio. Renovations needed but well worth it! Possible subdivision for a building lot. Close to all the wonderful amenities of coastal Madison including town center, shops, restaurants, great beaches and Rte 1 and I-95.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
