Buildings connect people to places—and keeping them safe, functional, and resilient takes the right expertise and a collaborative approach. At Klein & Hoffman, we bring architectural restoration and structural engineering expertise to the challenges of existing buildings. We listen closely, ask thoughtful questions, and develop creative, practical solutions that help our clients move forward with confidence. Since 1953, we have partnered with building owners, campus and facility managers, condominium association boards, and architects to assess conditions, address complex problems, and extend the life of their buildings. Our recommendations balance performance, preservation, and budgets, with our clients’ best interests guiding our work. Our experience spans high-rise buildings, residential communities, campuses, and treasured landmarks, including Shedd Aquarium, O’Hare International Airport, and Loyola University. From our offices in Chicago, Milwaukee, and Philadelphia, we connect clients with the people and knowledge needed to care for their buildings today and plan for what comes next. Working Together. Building Together.
