Overview
Spring Hill at Old Westbury sits on the 160-acre grounds of the former Phipps estate as a secluded, 24-hour guard-gated community. Its single biggest draw is the private 3-acre freshwater lake at its heart, complete with a floating boat house — and you build a traditional single-family estate to suit on a multi-acre lot with Kean Development.
Highlights
24-hour manned gate, real seclusion
A staffed gatehouse controls access around the clock, and the community is fully gated and secluded. For buyers who weigh security and privacy first, this is protection you can see every day.
A private 3-acre lake on historic estate grounds
Set on the 160-acre former Phipps estate, the community centers on a 3-acre freshwater lake with a floating boat house, framed by mature trees and rolling meadowland — the kind of established landscape a new subdivision can't manufacture.
Multi-acre lots, a single-family estate built to suit
This is build-to-suit: on a multi-acre lot, Kean Development designs and constructs a classic, traditional single-family estate home for you rather than handing you a stock floor plan. The community is small — the official site cites about 12 estate lots.
A wide span, from raw land to top-tier finished estates
What's available ranges from multi-acre raw lots (individual Spring Hill Lane parcels listed roughly $3.5M–$5.675M) up to completed Kean-built estates (about $28M–$38.8M). The finished homes have drawn third-party coverage — a useful reference point for buyers thinking about value and resale. These figures come from separate individual MLS/brokerage listings, not a developer price sheet.
