The following summer season, Mr. Rice took Mr. Roth up on the give and discovered that he liked Mr. Roth’s getaway in the Pines extremely much indeed. But as he strolled along the boardwalk, it was a further household that commanded his interest: a large, pyramid-shaped building with cedar shingles on three sides and a soaring triangular wall of metal and glass on the fourth.

It was virtually as if a significant mock-up of I.M. Pei’s Louvre Pyramid had washed up on the seaside.

Intrigued, Mr. Rice began inquiring all around and learned that the dwelling was owned by Jeff Mahshie, a vogue and costume designer. So when Mr. Rice’s close friends encouraged him to ask for a tour, he barely hesitated right before strolling about.

Outdoors, Mr. Hayes extra a poolside guesthouse comprising three connected packing containers with pyramidal roofs.

For the primary suite, he put in a Norwegian Westnofa rosewood bed room established from the 1960s and classic French resin benches with multicolored geometric bases.

“Pretty a great deal everything is from all over the similar time period of time as the property,” Mr. Rice reported. “It’s my aesthetic anyway, but it turned out that I was picking matters that match.”

He opted not to make any significant architectural adjustments, but the home essential comprehensive repairs and updates, from changing rotten cedar boards outdoors to incorporating heat tape all-around pipes that would in any other case freeze in the winter season.

“Being on Fire Island, amongst the ocean and the bay, is truly tough on the properties,” he mentioned. “All the salt, the consistent humidity, et cetera. So every single 12 months I do a large venture. I did the electrical system and the plumbing program. This slide, it is likely to be the replacement of all the doorways and home windows.”

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