Manhasset is an unincorporated community on Nassau County's North Shore, within the Town of North Hempstead. Known for the Americana Manhasset shopping center, the Manhasset LIRR station (34 minutes to Penn Station), and residential neighborhoods that rank among Long Island's most valuable, Manhasset attracts homeowners who invest in quality construction.
The housing stock ranges from pre-war estates on Shelter Rock Road and Plandome Road to mid-century colonials in the Munsey Park and Strathmore Vanderbilt sections. Lot sizes are generous by Long Island standards -- many exceed 10,000 square feet -- which provides ample room for sunroom additions without setback issues.
Median home values in Manhasset exceed $1.3 million. Additions that increase living space while maintaining architectural quality deliver strong returns at resale. A well-designed sunroom adds 150-350 square feet of bright, usable space at a fraction of the cost of a conventional room addition.
Long Island Sunroom Co. holds Nassau County License #H3421100000 and has completed sunroom projects throughout Manhasset's residential neighborhoods.
Munsey Park -- An incorporated village within Manhasset. Homes are predominantly colonials and Tudors on lots of 10,000-20,000 sq ft. The village's setback requirements (typically 25-foot rear, 10-foot side) still allow generous additions on most properties.
Strathmore Vanderbilt -- A section of large colonials and split-levels built in the 1950s and 1960s. Many homes have concrete patios that are candidates for patio enclosure conversions. Rear yards are typically 40-60 feet deep, providing room for additions up to 16-20 feet.
Plandome Heights and Plandome Manor -- Incorporated villages along the western edge of Manhasset, closer to Manhasset Bay. North-facing properties here have water views that benefit from four-season sunrooms with floor-to-ceiling windows designed to frame the view. Waterfront proximity means salt-air-rated materials are essential.
North Strathmore -- A mix of ranches, capes, and colonials on moderate lots. Straightforward sunroom additions with studio or gable roofs. These properties are the most common candidates for three-season sunrooms in the $18,000-$32,000 range.
Manhasset homes tend to be well-maintained and architecturally consistent within their neighborhoods. A sunroom that looks bolted-on detracts from the property. Our design approach in Manhasset prioritizes:
Many Manhasset homeowners choose four-season sunrooms with insulated windows and HVAC integration, creating a year-round room that functions as a primary living space. At Manhasset's price point, the investment in a fully insulated room returns better value than a seasonal-use space.

Homeowner Reviews
Real homeowners in Manhasset who chose Long Island Sunroom Co.
“Had a leaking sunroom installed by another company five years ago. Tom's team ripped it down, fixed the foundation issues, and built a proper four-season room. Night and day difference.”
