C.A.P. Turner Building to be Repurposed for Affordable Housing
The Cameron Transfer and Storage Co. building (756 N. 4th St.) in the North Loop neighborhood was slated to be torn down; those plans were scrapped when the developer learned that the building might be the oldest project in Minneapolis by Claude Allen Porter (C.A.P.) Turner, an internationally known structural engineer who lived and worked in the Twin Cities for several years.
Meghan Elliott was quoted in the Star Tribune article by Jim Buchta:
"In the early 1900s, Turner began using a construction technique that helped revolutionize the way buildings and bridges were built. That “flat-slab” support system was known as the Turner System or the Spiral Mushroom System because it used reinforced concrete slab floors supported by thick concrete posts that flare at the top. The technique helped reduce the number of supporting posts needed in a building, creating a more open, flexible space.
Meghan Elliott, founder and principal at Preservation Design Works in Minneapolis, said that some say the flat slab idea was first used in Europe."
Now, the rehabilitation of the historically significant building into affordable housing will be utilizing historic tax credits. Read the Star Tribune article here for more information on the proposed development.
