Philip Wasilausky, owner of this three-bedroom, three-bath, circa-1850 Centerport residence listed for $649,000, knows a thing or two about living in historic homes.

That’s because Wasilausky, a native of Connecticut, grew up in a pre-Revolutionary War home there. So when he and his wife, Barbara, first set foot in the Little Neck Road home, which just went into contract, the connection was immediate.

Situated on a 0.8-acre lot, the house includes a 20-by-20-foot kitchen that was updated in 1992 and has become a focal point.

The home, which is a Town of Huntington landmark and listed in the National Register of Historic Places, has been upgraded many times during the 20th century, says listing agent Kim Schultze of Coldwell Banker Residential Brokerage. The oldest portion is now a parlor with a brick fireplace and wood-burning stove, a bedroom, a bathroom and a second-floor master bedroom.

A living room and two upstairs bedrooms were added in 1903, and a two-car garage was constructed in 1945. The enclosed glass breezeway was added in the 1970s and connects the house to a circa-1850 barn, which is attached to the two-car garage.
