Historic Upper Main—The 1000 Block

Dubuque’s Historic Upper Main Street Revitalization (The 1000 Block) project involved the complete rehabilitation of six blighted buildings, restoring fourteen historic storefronts and creating 30 quality affordable housing units.


This $7 million project restored the building's storefronts to historic accuracy and has helped to spark an economic revitalization of the area. The 1000 Block is now home to eight retail and entertainment businesses, as well as 30 quality apartment units. It has become a safe and walkable neighborhood with access to services and transportation. Additionally, this renewal made great use of sustainable and environmentally friendly materials.

Roshek Building

In 1894, two brothers and another partner set their sights on Dubuque, Iowa to see their mercantile dreams come to fruition. Soon, the party of three became a brotherhood, literally, that would be handed down to their respective sons, and the family grew their turn-of-the-century, one-floor operation on Main Street into four different locales to finally construct a nine-story retail empire that anchored on 700 Locust Street from 1929-1969.

It then evolved into office space with a major renovation in the early 1970s. The building, now a mixture of office space and retail, was rehabilitated in 2009-2010 by a cooperative effort among many Dubuque entities under the auspices of Dubuque Initiatives.

Located in the heart of downtown Dubuque, the Roshek Building has a walkability score of 97 and is the undeniable hub of the cities’ downtown offerings with convenient access to parking, public transportation, restaurants, park, and plaza. An on-site professional management team and maintenance staff assures building upkeep to include landscaping, on-the-spot snow removal, common-area cleaning, and site supervision.

Schmid Innovation Center

The first project in the Historic Millwork District was the CARADCO Project, which is now known as the Schmid Innovation Center/CARADCO Lofts. The Carr, Adams, & Collier Company (CARADCO) Main Plant Building is a former millworking factory in what was once the nation’s largest window and door manufacturing company. CARADCO occupies an entire city block, was built between 1880 and 1906, and is adjacent to Dubuque’s downtown, walkable, working class neighborhoods.


CARADCO’s revitalization in a pedestrian-friendly, urban-cultural atmosphere supports sustainable design principles that include the reuse of existing buildings and infrastructure, energy-efficient features, complete streets, and connectivity to jobs and services in a downtown setting. By establishing a vibrant mix of residential, commercial/retail, and non-profit tenants, CARADCO creates a sense of place that exhibits the qualities of true urbanism — density, diversity, energy, and sociability.
