This Modern house on Shelter Island was designed to resemble a nautilus shell. Recently restored, it is on the market for $1.649 million.

The seller, artist Joseph La Piana, purchased the curved two-bedroom, pond-front house four years ago and restored it, replacing paneled surfaces with clear cedar and renovating the kitchen and bathrooms.

“As an artist, you see things and have an imagination for things, and see what it can become,” La Piana says.

The multilevel living area, with brick and polished concrete floors that extend out to a patio, overlooks the secluded, 2.3-acre property, which La Piana landscaped, installing a saltwater gunite pool.

The different levels and openness of the space makes the home feel larger than 1,450 square feet,

“When you’re there, you really feel like it’s you and nature,” says listing agent Penelope Moore of Saunders & Associates.
