Welcome to 31 Deer Run, a custom built masterpiece nestled in the highly sought after and coveted Deer Run Estates, in the heart of East Islip. This 4 bedroom, 2 full/2 half bath residence makes its first impression with a jaw dropping 1,600 lb pivot entry door, hand crafted by Modern Steel Doors of Tucson, setting the tone for the craftsmanship found throughout. The chef's kitchen is a true showstopper, with custom Milano cabinetry, quartz countertops, and a complete Jenn Air suite including microwave, dishwasher, stove, hood, warming drawer, and refrigerator. Throughout the home, custom Milano interior doors and radiant heated polished porcelain floors flow through every room for consistent, luxurious comfort. Cozy up beside the natural gas fireplace, or retreat to the primary suite, a private oasis with a walk-in shower and floating soaking tub that leads directly out to the back deck. A versatile bonus room rounds out the interior, offering space for a gym, media room, or home office. Outside, the professionally landscaped grounds are fully fenced with rear gates and framed by a long blacktop driveway, with an exterior finished in Stucco/Gatto plastering lined with 1.5 inch foam completed in 2023, and a roof replaced in 2020. All electric on the property runs underground for a clean, unobstructed look, and all gutters flow to dry wells. The garage is heated with a built in second refrigerator, pull down attic and is fitted with a truly one of a kind door custom made in Belize, originally built for a parking garage in NYC. The backyard is a resort style oasis, anchored by a newly lined in ground pool with an automatic pool vacuum. Entertain year round with a natural gas BBQ and fire pit, both fed by dedicated natural gas lines, or unwind by the Trex composite decking and ornamental pond. Behind the scenes, the home is just as impressive: a Navien boiler and hot water heater installed in 2022, 3 zone central air conditioning less than 3 years old, a central vacuum system, a large capacity washer and dryer, and a whole house appliance package from 2020 and a whole home hard wired security system with 3 Ring cameras plus 8 additional cameras to provide comprehensive peace of mind.Additional highlights include over 50 owned solar panels, paid in full, a solid stainless steel dolphin fountain sculpture, a electronic doggie door, garbage disposal, decorative planters flanking the driveway, side lights on the garage, and a shed for pool storage and equipment. Ideally situated just moments from pristine beac
