O’Neil Pennoyer Architects is a full service firm founded in 1987 that specializes in the sustainable design of regionally appropriate residential and small institutional projects. Whether a campus or a country house, our first priority is to shape, through a determined integration of landscape design and architecture, the exterior spaces that form the identity of every place or institution. We have recently been awarded LEED platinum certification from the U.S. Green Building Council for a single-family house. Our goal going forward continues to be to work collaboratively with our clients, to design and construct projects that, both architecturally and environmentally, best represents their values.
