With seven bedrooms and seven bathrooms, this shaker-style home complete with shingles is reminiscent of the Hamptons homes favoured by New York's rich and famous.
The owner has transformed a clearing in the native scrub, just a stone's throw from Portsea's moody backbeach, into a hidden enclave of tranquillity and style.

It is divided into four "pavilions", essentially separate buildings bound together by a 3m-wide glassed hallway running 35m through the centre of the house.
Its showpiece pavilion houses an enormous open living, dining and kitchen area looking north over lush lawns and a stunning infinity pool to native bushland.
The kitchen has an old-style black enamel Aga stove that stands out amid the stark white Corion cabinetry, which is finished with leather and stainless steel handles.
The kitchen even boasts a lift to ferry groceries from the 10-car garage hidden below the house.
Another pavilion houses a master suite with a pair of mirror-image en-suites, two dressing rooms and a plush carpeted formal lounge.
The "second pavilion" has four bathrooms, five bedrooms, including a second master suite, and an enormous laundry.
Another, called the "children's pavilion", includes a rumpus room, a dormitory, bathroom and dressing room.
