An Octagonal Home in Grahamsville/Napanoch

  |  November 20, 2025

Octagon houses were made popular in the mid-19th century by amateur architect Orson Squire Fowler. Their shape made the homes easier to heat than traditional four-sided houses.

Over the years, octagon houses have been preserved for their beauty and history, such as The Octagon Asylum on Roosevelt Island in New York City. Today, Upstater is at an octagon house built in 1980 in Grahamsville, Sullivan County (which we suspect may be its mailing address, because physically it appears to be in neighboring Ulster County’s Napanoch). Unlike its granite-lined NYC counterpart, this home’s facade is charcoal-stained wood.

The interior is roomy (1,768 square feet) and comfortable, with lots of windows sending natural light to its core.

The kitchen is the heart of this home, as the house’s central pillar rises in its center.

The hardwood flooring complements the raftered ceiling in the kitchen, which has butcher-block counters on top of white cabinetry and gleaming, stainless-steel appliances. There is more than enough room for a dining table large enough for a Thanksgiving feast.

Fixtures such as this stairway are simple and functional, allowing for creative leeway elsewhere.

The peak of the house offers lighthouse vibes. The house has three bedrooms: This is one of them.

We love the moon-shaped windows.

This bath has tile cleverly designed to mimic wood, and it runs clear through to the glassed shower stall.

A stone shower and a standalone soaking tub are the main features of this second bath.

How could you not want to wake up to this every morning? A bright and beautiful room.

The house sits on 7.7 acres, with distant mountain views. Grahamsville is a pretty part of Sullivan County, in the town of Neversink. Napanoch is adjacent, just across the Sullivan/Ulster County line. The home is between Sundown Wild Forest and the Rondout Reservoir; it’s about a 20-minute ride to Ellenville for provisions on Canal and Center Streets, and a lovely meal at Morning Sunshine. The house is listed at $689,000.
