The owners of this historic East Hampton home did an extensive renovation, blending its antique features with striking modern design. It is on the market for $3.995 million.

When Don Ashby and his wife, Kathy, purchased the home in 2012, it was made up of three separate structures — the main house, which dates back to 1680, a house that was added on in the 1880s and a section from the early 1900s. The Ashbys lifted the house, installing a new foundation and adding a full basement, which now houses a gym, media room and an en-suite bedroom. They also removed the 20th century addition and eliminated the third floor in the oldest structure, creating a double-height ceiling master bedroom and stairway.

The couple kept almost all the original framing, and the five-bedroom home has lots of exposed wooden beams, along with contemporary touches such as a sleek kitchen with Boffi appliances an uplit staircase.

“We liked the idea of a historic house, but we wanted to make it more modern,” Don Ashby says.

The half-acre also has a heated gunite pool, gardens and two-car garage.

It is listed with Beate Moore and Jennifer Newman of Sotheby’s International Realty.
