Des Moines-based Neumann Monson Architects has breathed new life into a historic industrial warehouse in Iowa by transforming the 117-year-old building into LEED Platinum multi-tenant offices. Commissioned by Blackbird Investments, this eco-friendly renovation not only involved salvaging and reusing original elements in the century-old building, but also inserting energy efficient systems including a combination of geothermal and solar that have helped the project achieve net-zero energy certification. Dubbed Market One, the thoughtfully restored structure has sparked greater revitalization in the surrounding industrial neighborhood and is the state’s first commercial building to produce more energy than it consumes.
Completed in 2015, Market One comprises 55,000 square feet of renovated warehouse space in addition to 1,887 square feet of added construction. Originally built in 1901 as the offices and manufacturing center for the Advance-Rumely Thresher Company, the warehouse comprises three main floors as well as a basement. While renovating the building, Neumann Monson Architects also added a rooftop office and deck. The block immediately east of the building was converted into a surface parking lot with an overhead photovoltaic canopy.

“The project achieves a rich, nuanced dialogue between new and old,” Neumann Monson Architects said. “In some locations, the two are carefully delineated. In others, modern interventions blend in and take a backseat to historic character. Throughout the building, transparency and compatible finishes allow space to flow freely. To maintain the large volumes’ spatial continuity, the design locates new enclosed areas at the building’s core and terminates their walls well below the ceiling plane. Extensive glass and polycarbonate interior partitions allow light penetration deep into the building and maintain open visual connection throughout each floor level.”
Local, sustainable and durable materials were used throughout Market One. A planned green belt and pedestrian trail will soon be added to the north of the building and a new Amtrak station will also be added in the future.
