TERRA is involved with the partial demolition and new building addition to the Forest Preserve District of Cook County’s clubhouse at the Rolling Knolls preserve in Elgin, Illinois. The building addition will be constructed to create a new gathering space that overlooks the ravine and natural topography and landscape below. The site’s 20-foot grade change means creative strategies for sidewalk, berms and retaining walls were engineered to accommodate a handicap-compliant building entrance to meet the American with Disabilities Act.
