While New York is home to several famous Frank Lloyd Wright structures, including the renowned sites in Buffalo and the private Usonian homes in Westchester, many travelers are unaware of the hidden architectural gem located on Petra Island. Situated in Mahopac, approximately 50 miles north of Manhattan, this unique property offers seasonal public tours that provide an intimate look at organic architecture. For those looking for a sophisticated day trip from the city, the island serves as a perfect destination for design enthusiasts.
The history of the property began when Joe Massaro, a former sheet metal firm owner, purchased Petra Island in 1995. At the time, the island featured the Chahroudi Cottage, a 1,200-square-foot guest house commissioned by Ahmed Chahroudi and completed in 1952. Frank Lloyd Wright originally designed the cottage while he was focused on the construction of the Guggenheim Museum in New York City. Though the cottage was used as a summer getaway for years, it was only part of a much larger vision that Wright had conceptualized for the island.
Massaro eventually acquired five original drawings from the Chahroudi family, which included floor plans and sketches for a 5,000-square-foot main residence. Following his retirement, Massaro decided to realize the unbuilt project. He enlisted architect and Wright historian Thomas Heinz to finalize the interior details based on the original concepts. Because the Frank Lloyd Wright Foundation did not oversee or endorse the construction, the home is technically classified as “Wright-inspired” rather than an official Wright residence. Nevertheless, the craftsmanship and adherence to the architect’s aesthetic are undeniably impressive.
The main house is a study in grand scale and natural integration. It features a dramatic 30-foot cantilever that hangs over Lake Mahopac, a design feat intended to rival the boldness of Fallingwater. The interior incorporates the island’s natural landscape, including a massive indigenous boulder that serves as a focal point in the main entry hall. Unlike many historic Wright properties, this modern interpretation includes contemporary comforts such as central air conditioning and radiant floor heating, while maintaining signature details like redwood-beamed ceilings and multiple fireplaces.
Visitors can explore the Petra Island homes during a limited season that runs from June through October. Because of its location, a visit here can easily be paired with other regional highlights. Within an hour’s drive, travelers can visit the Storm King Art Center, the Walkway over the Hudson, or the historic towns of Garrison and Cold Spring, making it a comprehensive cultural excursion through the Hudson Valley.
