About the building
The 22-story Mid-Century Modern Grant-Deneau Tower was the first modern commercial high rise in downtown Dayton. Originally built in 1970, it is now being repurposed as mixed residential and commercial space that will include 160 luxury apartments — one of the first commercial-to-residential conversions in the State of Ohio.
