Our innovative process of working across several disciplines connects our analytical and technical skills with our preservation knowledge, relationships, and resources to make historic preservation projects happen. The value of our services stems from our unique integration of applied research with preservation design and real estate development services. Our project and business success is driven by a commitment to research, academic teaching, and scholarship where we actively explore and develop strategies to remove barriers to building reuse. We extend our network to a national level through publications and public speaking.
