12 Nostrand Avenue sits on 19,602 square feet — a little under half an acre — in Brentwood, in the Town of Islip. The Colonial was built in 2014, which means the wiring, the windows and the mechanicals all date to the same decade. It has been maintained since. That shows before you reach the front door.
The main level runs living room, family room, formal dining room, kitchen. Four rooms, four jobs. Dinner can be formal on one side of the house while the television stays on in the other. Upstairs, the primary suite is expansive: walk-in closets, an en-suite bath with a jetted tub and a separate shower. Four more bedrooms share the floor.
Below, the basement is finished — a full additional level of usable square footage that answers to whatever you need it to be. Outside, the yard holds a heated salt combo in-ground pool and a pool house with a full bathroom, so nobody tracks water through the kitchen to change. There is still lawn left over.
An attached garage handles the car and the overflow. Leased solar panels sit on the roof, working on the electric bill. Across 3,800 square feet, four full baths mean the morning does not become a queue. Brentwood School District.
A full Matterport capture of the house — walk it room to room at your own pace, as if you were standing in it. Measured floor plans below.
Brentwood sits in the middle of Suffolk County, in the Town of Islip, with the Sagtikos State Parkway running north–south alongside it and the Southern State Parkway and Long Island Expressway framing it above and below. The Brentwood station on the LIRR Ronkonkoma Branch is close by. South of here the land runs down to the Great South Bay at Bay Shore, where the Fire Island ferries leave, and Heckscher State Park holds the shoreline east of that.
