Key Facts
Description
In a market dominated by the expected, this deceptively spacious geodesic dome home in Raritan Township offers something altogether different. Inspired by the visionary designs of Buckminster Fuller, its distinctive form reflects a philosophy of efficiency, sustainability, and living in harmony with the landscape. What makes this property especially compelling is not just its architecture, but the surprising amount of space it contains inside and out. The true star of the property is the backyard. Deep, grassy, and partially preserved, it stretches toward the neighboring grounds of Desmares Elementary School, creating a sense of openness that is increasingly difficult to find. A large kitchen with abundant workspace adjoins the family room, where sliders connect directly to the backyard. Upstairs are three bedrooms, a finished attic area reached via a ladder, and two full bathrooms, including a private bath in the primary suite. Two full bathrooms serve the main level near a flexible room that could serve as a guest room. An attached two-car garage opens into a spacious mudroom, setting the stage for a home that balances character with practicality. Rare for its alternative design, generous footprint, and remarkable setting, here is a chance to own not just a home, but a piece of very cool architectural history!
