You travel through another dimension, a dimension not only visual and sound, but also mental. A trip to a wonderland called East Hampton, where hydrangeas bloom as big as grapefruits and rosebushes fall over the picket fences. The old clapboard house has a sign in front of you. Your next stop: the Old Money Zone!

Signs of the Old Money area: old specimen trees arching over croquet and badminton lawns and indoors, a restrained good taste. Expect Colefax & Fowler prints on curtains, chairs and linens, plus heaps of antique furniture and, most importantly, plenty of evidence from an educated and wealthy collector.

Indeed, American folk art, majolica, antique hat forms, ironstone, antique birdcages, brass shoes, cranberry glass, and modern and contemporary art were all passions of the late owner of this East Hampton estate, Alice Netter, died in July at the age of 87. Gardening was another passion of Netter, as is easy to see from the photos of the property. According to her obituary in the East Hampton Star, “Her gardens were magnificent, only to be surpassed by the floral arrangements she created of them, as centerpieces at her dinner parties.”

She and her lawyer husband bought the Jericho Lane estate in 1977. (Mr. Netter died in 2009.) Now their Shingle-style home, built in 1901 and located on 2.4 acres near the ocean, in the coveted section of the East Hampton Estate, is available for sale for $17.9 million. The listing agent is James Petrie at Compass.

Anyone looking to channel their newfound fortune into a majestic estate need look no further. The historic house includes a pool and cabana in its lovely park-like grounds. The estate is, in fact, made up of two parcels that could potentially be subdivided: 1.3 acres on Tony Jericho Lane, plus an additional vacant 1.1 acre parcel that adjoins the perhaps even more toned Apaquogue Road, site of the legendary Gray Gardens estate.

Sure, the house could use a few updates, but it’s not worth the quibble because anyone paying $18 million for a house is sure to spend even more money on upgrades and customizations. The main floor of the home features a spacious formal living room with fireplace, a formal dining room, and a large kitchen with dining area. A huge veranda includes sliding doors at either end, to take advantage of cool summer breezes, but also provides protection on those summer buggy nights. A powder room and a boudoir with a fireplace complete the main level.

The upper floor contains seven bedrooms. Three guest bedrooms have private baths and three more share a bathroom down the hall – give those bedrooms to summer guests you don’t like so much – while the master suite offers a charming living room, dressing room and an adjoining bathroom.

Outside, the gunite swimming pool is surrounded by a large sunny terrace and a pool house with another bathroom. Opposite, the circular driveway, the car park and the adjoining two-car garage offer plenty of parking space. And of course, all this just minutes from the most beautiful beaches in the world.
