The Locust Valley, Long Island home of designer Alfredo Paredes is an absolute beauty. Built in 1929 and filled with original architecture, it has Ralph Lauren vibes (he was Chief Creative Officer for Ralph Lauren Home for 33 years) and despite being a mansion, is as cozy as can be. That great room with wood-clad barrel vaulted ceiling is soooo dreamy. Timeless with a touch of elegance alongside a touch of ranch. Photos: Noe DeWitt.
