The upcoming summer months, Mr. Rice took Mr. Roth up on the provide and discovered that he liked Mr. Roth’s getaway in the Pines extremely substantially without a doubt. But as he strolled alongside the boardwalk, it was one more residence that commanded his awareness: a big, pyramid-shaped creating with cedar shingles on 3 sides and a soaring triangular wall of steel and glass on the fourth.

It was practically as if a significant mock-up of I.M. Pei’s Louvre Pyramid experienced washed up on the seashore.

Intrigued, Mr. Rice started inquiring all around and realized that the dwelling was owned by Jeff Mahshie, a fashion and costume designer. So when Mr. Rice’s good friends encouraged him to request for a tour, he hardly hesitated just before strolling around.

Mr. Mahshie answered and welcomed him within — and Mr. Rice could not feel his eyes as he took in the sweeping see about sand dunes to the ocean and the bay.

“We walk in, and it’s just remarkable,” Mr. Rice explained.

The property was created by Julio Kaufman, an Argentine architect, in the early 1960s. Then in 2001, the writer Paul Rudnick acquired it and employed a different architect, Hal Hayes, to update and broaden it. It was Mr. Hayes who added the metal-and-glass wall, and who reconfigured the interior to make the prime degree an open up residing-and-dining area with a kitchen area and the reduced level an expansive most important suite. Outside the house, Mr. Hayes extra a poolside guesthouse comprising 3 connected boxes with pyramidal roofs.

Mr. Rice marveled at the compound, engaged Mr. Mahshie in discussion about scripts he spied on tables and finally advised him that he was blessed to are living in this sort of a amazing residence.

“And he explained, ‘Actually, I’m imagining of promoting,’” Mr. Rice recalled.

Mr. Rice happened to be in the approach of selling his Harlem brownstone, which would supply him with the cash to invest in the residence.

“I just fell in really like with the household and imagined all the things about it — together with the system by which I was acquiring it — was incredible,” he stated.

Immediately after closing in December 2018, he wanted to furnish the household, but he was prepared for that, way too: An aficionado of design, Mr. Rice runs a side small business identified as Supervision, obtaining and promoting vintage midcentury-modern-day furniture and extras. For the dwelling area, he brought in a pair of teak-and-cane sofas built by Peter Hvidt and Orla Mølgaard-Nielsen in the late 1950s, additionally a pair of slouchy armchairs with lacquered wooden frames and blue suede upholstery from the 1970s. For the key suite, he put in a Norwegian Westnofa rosewood bed room set from the 1960s and vintage French resin benches with multicolored geometric bases.

“Pretty significantly almost everything is from about the same time period of time as the home,” Mr. Rice said. “It’s my aesthetic in any case, but it turned out that I was deciding on issues that suit.”

He opted not to make any major architectural alterations, but the house necessary considerable repairs and updates, from replacing rotten cedar boards outdoors to introducing warmth tape about pipes that would normally freeze in the wintertime.

“Being on Fireplace Island, between the ocean and the bay, is seriously challenging on the houses,” he explained. “All the salt, the regular humidity, et cetera. So each 12 months I do a major task. I did the electrical process and the plumbing system. This slide, it’s likely to be the replacement of all the doors and windows.”

In all, Mr. Rice estimated that he has used about $400,000 restoring and maintaining the household.

He has also flipped the script on proudly owning a summer residence, shelling out the the vast majority of the yr on Fire Island and periodically returning to his apartment in Williamsburg, Brooklyn. When he isn’t living in the pyramid, he rents it out on Airbnb and Vrbo, the place it can fetch a lot more than $3,000 a night in the summer season. “It is my key residence,” he reported, “but I do hire the home out in the high time to enable defray all of the ongoing expenses.”

And if he misses a couple very hot, sunny days in July and August, that is Okay. “Looking by that window,” he said, “no make any difference what the weather conditions is — a storm, a snowstorm, a sunny day or clouds heading by — is just fantastic.”
