12 Nostrand Avenue.

Nostrand Avenue runs through the middle of Brentwood, in the Town of Islip, where the parkways cross Suffolk County and the Great South Bay is a short drive south. The house was built in 2014 and sits on 19,602 square feet — a little under half an acre — with the pool and the pool house set behind it.

The main level holds a spacious living room, a family room, a formal dining room and a well-appointed kitchen. Upstairs, the expansive primary suite has walk-in closets and an en-suite bath with a jetted tub and a separate shower. Four full baths serve the house. The finished basement adds living space that can be assigned whatever job you need done.

Outside is the argument. A heated salt combo in-ground pool, a pool house with a full bathroom, and open ground around both for chairs, a table, or nothing at all. An attached garage handles the car and everything that accumulates near it. Leased solar panels sit on the roof, working on the electric bill.

The whole house shares one birthday. Roof, systems, windows and finishes all date to 2014, and the place has been beautifully maintained since. Three thousand eight hundred square feet across five bedrooms means the rooms are sized to be used, not admired from the doorway.
