Each home in the welcoming Solterra co-housing community has a name. This is Butterfly House, for its roof form, but also because of the way the dramatic, light filled interior makes your spirit soar. Energy Star home. High quality custom touches throughout. Lovingly cared for and updated by the current owner, an interior designer. Located between Durham & Chapel Hill, by Hollow Rock Nature Park, Solterra has an organic garden, dog park, walking trails, open meadows, common house for gatherings and more.
