This Long Island home that once claimed to be the country’s largest sustainable residence is back on the market

A 15,000-square-foot home on Long Island whose previous listing broker once said it was the largest environmentally sustainable residence in the nation has relisted with a $24.8 million ask.

The new listing price for the mansion at 88 Old House Lane in Sands Point is a little more than $13 million less than the $38 million the property sought when it first hit the market in 2015. Patch noted over the weekend that the home, built in 2014, has a Leadership in Energy and Environmental Design (LEED) certification.

Newsday reported four years ago that the residence is owned by a businessman in the technology sector who has preferred to remain anonymous. In designing the mansion that sits on the 3.8-acre property, the unidentified owner wanted to have water views of the Long Island Sound in every room.

The home’s exterior walls are made from porcelain and zinc, according to Newsday, which noted that its roof has gardens that use reclaimed water for irrigation. The home also has geothermal heat, solar panels and radiant floor heating.

“You can heat and cool this home probably for less than $1,000 a month, which is incredible for a 15,000-square-foot home,” Nest Seekers International broker Shawn Elliott, who had the listing for the property, told the newspaper in 2015. At the time, Elliott noted that the Sands Point estate was the largest environmentally sustainable residence in the country.

Not sustainable, however, was its initial listing price.

Newsday noted in its 2015 story that the Gold Coast home’s construction was beset by delays and difficulties finding contractors. Its owner put the property on the market that year, but by 2017 its ask had been reduced to $29 million. The listing for the home was removed that same year, according to Zillow.

A press release from October 2018, as well as a news story from the Island Now, declared that the home would be put up for auction with no reserve by Elite Auctions and Elliott. Auction materials touted the property’s modern architecture and grounds as being used to film NBC’s “The Blacklist,” Showtime’s “The Affair” and a Two Chainz music video production.

The Sands Point home has eight bedrooms, nine bathrooms and four half-bathrooms, as well as amenities like a steel floating staircase, two chef’s kitchens, an elevator, an indoor pool, a golf green and a court that can be used for either squash or basketball.

The estate returned to market in December at $28.8 million before taking its most recent price cut, to nearly $25 million, in mid-May. Sabreen Qaiyum of Coldwell Banker now has the listing. [Patch] — Aidan Gardiner
