ABOUT HPZS

AWARD-WINNING HISTORIC & SUSTAINABLE PRESERVATION DESIGN SINCE 1976
HPZS and its predecessor firms have been providing innovative architectural, preservation, and interior design services to a wide variety of public and private clients since 1976. The conventional A/E services offered by the firm are complemented by unique and specialized experience with Historic Preservation, Sustainable Design, Adaptive Reuse, Prefabrication, and Building Materials and Systems Failure Analysis. HPZS has received numerous national, state, and local awards for its work in these areas, and looks to the future focused on continuing to provide its clients the most sustainable outcomes with a palate of services in support of integrated and energy-efficient design.

Our projects have successfully restored, renovated and even saved some of Chicago’s and the Midwest’s most iconic historic architectural gems, from the Henry Hobson Richardson designed Glessner House, to the Rookery Building by Burnham & Root, the Dana Thomas House by Frank Lloyd Wright, and Louis Sullivan’s Peoples Savings Bank in Cedar Rapids, Iowa.
HPZS provides innovative design services for a wide variety of buildings and structures, both large and small, ranging from numerous projects at Chicago’s Museum of Science and Industry and The Chicago Temple Building, to the development of a full block-long commercial district at the University of Illinois at Chicago’s South Campus, to the redevelopment of the Chicago Housing Authority’s Dearborn Homes. HPZS has a global influence, with new and preservation projects located both domestically and internationally.
HISTORY & FOUNDING
The history of HPZS spans nearly a forty-year period and is deeply intertwined with the history of historic preservation in Chicago. Wilbert Hasbrouck, the original founder of HPZS, began his architectural career in Chicago establishing the Prairie School Press in 1961, publisher of the Prairie School Review, and later opening and operating the world-famous Prairie Avenue Bookshop with his wife Marilyn. After his years as the executive director of AIA Chicago from 1968 to 1975, Wilbert started his firm, Historic Resources – The Office of Wilbert R. Hasbrouck in 1975. At that time Wilbert was one of only two architects in Chicago who seriously promoted the preservation and restoration of the buildings that comprise the historic fabric of the city.
In 1986, after collaborating on the award-winning restoration of the Grand Traverse County Courthouse restoration, Wilbert Hasbrouck and Jim Peterson founded Hasbrouck Peterson. In 1991, Henry Zimoch joined his office with the firm, and along with Jay Sirirattumrong, the firm became the name by which it is known today. Today, April Hughes leads the firm as a 100% woman-owned business, bringing her expertise in award-winning sustainable design to the practice and leading the charge to “Preserve A Sustainable Future.”
HPZS has continued to work on historically significant projects locally, nationally, and internationally, including pioneering restoration work in Thailand which includes the 1768 former palace Boran Satan Phrachawangderm, currently occupied by the Royal Thai Navy, and the adaptive reuse of a 19th century finance ministry building as a Royal Textile Museum for the Queen of Thailand.
JUST™ 2.0 Certification
Currently, HPZS is the only Woman-Owned Illinois architecture firm and one of two organizations headquartered in Chicago to have a Just 2.0 label. Administered by the International Living Futures Institute (ILFI), the JUST™ program is a system of metrics intended to measure organization’s performance on a range of issues relative to their policies and business practices. The JUST™ program outlines 22 specific social and equity indicators that are housed with six general categories: Diversity and Inclusion, Equity, Employee Health, Employee Benefits, Stewardship, and Purchasing and Supply Chain. The result of participation in this program is the JUST™ label, a publicly accessible scorecard transparently declaring the firm’s current performance measured against these metrics. HPZS is proud to be included in these endeavors, marking the beginning of a new era of corporate transparency. Learn more in a letter from our CEO.
