MAINSPRING Developers focus on community, place and people. That is the core from which all real estate development, construction and creation should spring. We create special places in urban communities, at the intersection of existing architecture and places and the new or revitalized uses that foster, enhance and support communities. Responsible development must have at is core the components that allow residents to find their own sense of community and connection in the ever-tightening urban environment. By first understanding the community and its direction, MAINSPRING renovates, rehabilitates and builds properties in unique ways to serve the existing community, foster improved work/live opportunities and create lasting anchors.
