Rare build-ready acreage at the end of a quiet Brewster cul-de-sac, with the hardest part already done. This 5.88-acre parcel in the Town of Southeast’s R-60 district carries a Putnam County Department of Health approval, issued 5 June 2026, for a four-bedroom residence at 440 GPD: septic design, approved expansion area and approved well location, including the NYC DEP watershed review that stalls most lots in town. The file also holds a complete engineering set by John Karell Jr., PE, an engineered driveway profile, an approved erosion and sediment control plan, boundary and topographic survey, and percolation and deep-hole testing. Architect-drawn house plans for the residence are included in the sale — build them as drawn or hand them to your own architect. Approximately 1–2 acres are already cleared, so you can walk the homesite instead of imagining it, with mature hardwoods left standing for privacy. Minutes to I-84, I-684 and the Southeast Metro-North station. Approval runs through 5 June 2028. Buyer to drill the well (existing permit is non-transferable; 5 GPM sought, yield not proven) and to obtain the building permit. Subject to a 16.5-ft AT&T easement of record.
