About Us Our firm was established as an architectural sole proprietorship by Bob Winkels in 1981. In 1991, the firm was incorporated as The Winkels Group, Inc., and began offering Construction Management and Project Management services, in addition to traditional Architectural services. The first ten years were highlighted by the development of the Valhalla Addition south of the Empire Mall. Bob managed this 100-acre development, which included Class A office buildings and apartment buildings. Since 1991, The Winkels Group has offered traditional design services, as well as design/build, criteria development, construction management and project management. Our design experience is highlighted by several school projects, plus office and retail work for the C.J. Callaway’s Complex, CorTrust Bank, office buildings for LodgeNet and DialNet, and renovation of the Carnegie Library into a Town Hall for the City of Sioux Falls. We have provided criteria development services for many public and private design-build projects, including two parking ramps for the City of Sioux Falls, Lodgenet Entertainment’s corporate headquarters, the retrofit of the Sioux Falls Arena to accommodate hockey, a law enforcement building for the City of Mobridge, and OEM’s assembly facility in Watertown. Our project management experience includes the Washington Pavilion, the Minnehaha County Jail, and St. Joseph Cathedral restoration/renovation. |
