Leading Double Lives: The History of the Double House in Des Moines, 2005

How people choose to live depends on a variety of social and economic circumstances. Single family dwellings, extended family compounds, and communal apartment blocks are all forms of residential architecture that have ancient roots and occur in every culture. Each form both reflects and affects the living styles of the people who reside there. The double house, which shelters two families in units separated by a wall or floor, balances the convenience of an apartment with the psychological comforts of a home. During the mid to late nineteenth and early twentieth centuries in the United States, the double house was hugely popular in some cities, such as Minneapolis and Milwaukee, but only a minimal presence in Des Moines

Iowa Department of Cultural Affairs, Strategic Plan 2012-2015

The Department of Cultural Affairs was created in the state government reorganization in 1986. The department’s two divisions, the Iowa Arts Council and the State Historical Society (SHSI) have a much longer history of service to Iowans. With such a rich history, it is fitting that the Department of Cultural Affairs calls the State Historical Museum home, a facility which collects, preserves and showcases Iowa’s treasures that itself can trace its roots in state government back 120 years. Generations of Iowans have been touched by the programs and services provided through this department. Though organized as one department, the DCA has never undergone strategic planning as a single, cohesive organization. With a desire to move forward as a stronger, more unified entity, a departmentwide strategic planning process becomes critical to future success as the department continues to better assess its resources and expertise internally, while ensuring it is focused on the common goal of leveraging cultural resources across the state of Iowa.
