Warehouse No.1 completed construction in 1904 on the site of the former Hansen Hop & Malt Company, which was destroyed when a fire ravaged the Third Ward in 1892.
The building constructed at 120-134 Jefferson Street was given the first permit for a storage facility in Wisconsin, earning it the designation Warehouse No. 1. The original cost to construct the building was $160,000 and the design was much more elegant than many of the other freight structures in the area.
Designed by noted architect Herman Esser, Warehouse No. 1 continued to serve as the Hansen Storage company headquarters until 1974.
In 1978 the building was sold to Badger By Products, leased back to Hansen Storage and finally vacated in 1981, when it's ownership then changed hands repeatedly until it was purchased in 1998 by Corcoran Place, LLC.
The buildings four floors of open and lofty interior space measuring approximately 75,000 square feet have underwent major interior renovations to offer Milwaukee area businesses unique office space and a comfortable and casual work atmosphere.
