The ADGWC, Inc. is fully committed to the revitalization of the historic site of the A.D. German Wholesale Company. This site consists of two landmark structures, connected by a shared canopy. Local entrepreneur, Albert Delvino German, built the first warehouse on Hazeltine Street in 1912 to house his wholesale business. His early commercial success lead to his most lasting achievement, constructing the innovative 4 story warehouse on Church Street designed by master architect Frank Lloyd Wright. The rehabilitated warehouses will include exciting interior and exterior spaces, permitting this historic complex to become a viable, compatible and sustainable multiuse property.

The ADGWC, Inc. has retained preservation specialists, Isthmus Architecture, Inc. ( to oversee the rehabilitation of both buildings. In November 2015, working with the ADGWC, Isthmus completed a Revitalization Feasibility Study to assess the potential scope and success for a project. In March 2017, Isthmus Architecture and consultants completed an intensive condition survey of the cast concrete frieze that dominates the fourth story Wright structure. This resulted in a Preservation Plan for the architectural concrete elements which are of great historic significance.

Plans and specifications for the actual rehabilitation are being prepared by Isthmus Architecture for the project with an estimated cost of $4 million. Based upon these documents, the ADGWC, Inc. has been approved by the National Parks Service to receive a minimum of $1.3 million in historic tax credits to be used to help fund the rehabilitation. The ADGWC, Inc. is now completing a detailed business plan funded in part by a grant from the USDA. The ADGWC, Inc. is actively engaged in fundraising to raise the balance of required funds through grants, donations and other incentives. It is the goal of ADGWC, Inc. to begin the rehabilitation work in early 2020.
