Color rules in groovy Tarrytown style mashup

First off, we have to admit that this sprawling, playfully decorated ranch-style house would have been close to the aspirational dream home of a 1970s teenager we once knew (add some blacklights and Indian tapestries, and you’re there). Second, we’re not sure who might be in the market to pay $2.5 million for an aggressively styled home built in 1972, but we hope they’re out there.

In all seriousness, this 4,778-square-foot Tarrytown home is a spectacular example of its style and era, and it has original features intact and in what looks like excellent shape. Located on almost an acre of forested land with trails, a pond, and a flat, open areas for picnicking or whatever, it’s well-sited to pull off the indoor-outdoor living functionality it inherits from earlier modernism. It’s built around a courtyard pool with floor-to-ceiling, sliding windows/doors on all sides. It has a vaulted, beamed main room as well as two additional living areas—one a sunken room that isn’t quite a conversation pit, but close—and two stacked-stone fireplaces echoed by walls and built-in cabinets that also bring the exterior-wall material inside.

The home’s long, low lines create separate wings for public and private areas. The colorful decor extends to the wallpaper in the laundry room.

The house has four bedrooms and five bathrooms, with the master opening to the pool area.

Most of the rooms, including the sunken living area, open on to a deck and the foliage outside.
