CEM Design has built a reputation for excellence in providing award-winning architectural design for hundreds of commercial and residential clients. Our primary areas of focus are historic restoration and renovation, and environmentally sustainable “green” design. While these may seem to be very different areas of expertise, we believe they are essentially complimentary. The most sustainable building conserves and reuses the embodied energy of an existing building.We are licensed architects in the District of Columbia, Maryland, Virginia, Colorado, and Massachusetts, and we hold national certification (NCARB). We are LEED Certified by the US Green Buildings Council, Energy Star Partners, members of Green America and the Maryland Green Registry.
