A well-preserved midcentury is now up for grabs in Huntington, New York. Originally designed in the late 1960s by architect Andrew Geller, who was known for his sculptural beach houses in the coastal regions of New York, New Jersey, and Connecticut, the redwood-clad home sits on a one-acre lot about 40 miles from Manhattan.

Nestled on a secluded lot in the Long Island town of Huntington, New York, the 1968 dwelling was originally built for local residents Dr. Jack and Diane Lipman. The current owner, who acquired the home in 2004, treated the space to a thorough remodel in an effort to preserve much of the structure’s original midcentury character.

The 4,250-square-f00t home offers generous-size living areas, including a trapezium great room off the foyer-which is the "most impressive room in the whole house," according to the current homeowner. "The soaring space is a complete surprise to visitors who first see the home from its simple, and seemingly low-lying, front entrance," the owner continues. "It is certainly the heart of the house, as it allows you to see all of the public spaces and most of the upper floor."

An expansive great room with double-height ceilings and ample seating is located near the main entrance. A stamped-sandstone wall, which is original to the home, serves as a blank canvas for collected artwork while adding further dimension and texture to the space.

Tall ceilings punctuated by wooden beams enhance the great room’s grand sense of scale, while sliding glass doors allow the interiors to mingle with the home’s lush, landscaped setting. Original details can be found throughout the two-level dwelling, including exposed brick, stamped-sandstone walls, and parquet floors. The structure’s geometric form represents what became known as a signature element of Geller’s architectural designs.

The large chef’s kitchen features custom cabinets, stainless-steel appliances, and refinished redwood floors.

Each of the home’s six bedrooms offer spacious and calming environments to rest and relax.

"Geller embodied postwar ingenuity and optimism in a series of homes in whimsical shapes," says listing agent Donna Spinoso-Gelb. "He applied his architectural artistry to the creation of this magnificent home, along with others in the area."

The primary suite includes a walk-in closet and spa-like bath outfitted with mosaic tiles.

As the result of a recent revamp, the dwelling-which is often referred to by locals as the Cool House-is now steeped with updated amenities, including a large chef’s kitchen fitted with all-new appliances. Multiple gathering areas can be found in the backyard, which is complete with a side patio and a heated in-ground pool. What’s more: The six-bedroom, four-and-a-half bathroom home is part of the Nathan Hale Beach Association, which offers private beach access as well as recreational facilities.

Another one of the bedrooms overlooks the pool in the backyard.

The view of the great room from the mezzanine level highlights the structure’s extensive glazing and towering red-brick fireplace, both of which are also original features.

"A few years before Geller died he visited the house for the first time in almost 50 years," says the owner. "Standing on the balcony, he looked around and pronounced, ‘I did good work.’ In reality, he had created a unique work of art," the owner continues. Last sold in 2004 for $870,500, the dwelling is back on the market-this time seeking $1,699,000. Scroll ahead for more of the Andrew Geller–designed masterpiece.

Two sets of sliding doors connect the great room to an expansive paved patio in the backyard.
