Revitalized in 2021, the ‘AMP House Offices’ converted a former Minneapolis electrical substation into a vibrant trio of small business offices. The original substation, built in the early 1900’s, is located on Garfield Avenue amidst a dense urban residential neighborhood and was decommissioned in the 1980’s. Vacant since that time, the neighborhood has affectionately called it the ‘Garfield Aquarium’ after installing large fish murals over the industrial windows. The renovation began with opening up the mezzanine floor by demolishing the floor adjacent to the large windows. The interior shell is largely left untouched to retain the history.
