Old Westbury Real Estate
An inland Gold Coast landscape of estate grounds, country houses and later residences on substantial parcels.
Old Westbury is an estate-market search rather than a conventional main-street search. Houses are often experienced through their grounds and approach, with the surrounding landscape doing much of the work. Its inland setting distinguishes it from the waterfront peninsulas of Kings Point and Sands Point.
History and architecture
Old Westbury Gardens provides the clearest public expression of that history. Westbury House was created for John S. Phipps and his family with designer George A. Crawley, using an English country-house vocabulary and formal gardens. The broader village includes surviving estate fabric alongside later residential development. Architectural presence may come from an original composition or a newer house designed for the setting.
Transit and the NYC connection
Old Westbury has no station of its own. Rail journeys begin at surrounding LIRR stations, with the choice depending on the address and required service. Road access is central to both the city connection and ordinary errands; this is not a walk-to-town substitute for Manhasset or Roslyn.
The property market
Useful land, architectural quality and the relationship between the residence and its grounds should guide the comparison. For sellers, the landscape deserves the same attention as the interior photography. For NYC buyers, the appeal is a more complete country-house setting without treating every acre as equivalent.
Property tax
About 1.71% of the purchase price a year: roughly $42,800 on a $2.5M house, within a range of $34,200 to $51,300.

A sale does not reset the assessment here, so the seller’s current bill is the number to underwrite. Ask for it, and check for exemptions (STAR, senior, veteran) that will not transfer.
