We build teams who build houses. Our Clients start the process, and their Architects offer the creative vision that give form to our projects. They join the team, along with Interior Designers, Landscape Architects, Engineers, Consultants, and Craftsmen, and provide both the art and the science of good design. We've been fortunate to have worked with some of the finest designers in the Northeast, and they, in turn, appreciate CORNERSTONE's expertise:
