We apply our core values of honesty, integrity , and hard work to everything we do…work, family, and community.

Founded in Detroit, Michigan in December 2011 by Brian Mooney and John Biggar, Integrity Building Group (Integrity) is a full service Construction Management and Architectural firm. Our mission is to provide the highest level of customer service for complicated construction projects, particularly historic renovation projects. Integrity Building Group was established on the belief that hard work and dedication to principles can make a difference, both to the success of a business and to the revitalization of the City of Detroit. Our firm specializes in adaptive reuse/renovation and historic restoration projects throughout Southeastern Michigan, with our primary focus being the historic districts of Detroit.

Integrity Building Group Detroit is extremely excited to be part of the team assembled for the renovation of one of Detroit’s most magnificent and culturally important buildings, the Grand Army of the Republic (G.A.R.). The G.A.R. is a legacy project for IBG Detroit and we are proud to contribute our part to the rich fabric and history of Detroit. We are es­pecially proud of the team of workers who have shown such a commitment and pride in the work completed to date.

We respect and understand the needs of clients, and are happy to look at either Construction Management or Architectural services. In many cases, the owner has chosen to combine both services to ensure prompt delivery and proper attention to budget concerns.

Please take a minute to look at our company information and we would be happy to give a list of happy customers both current and past. Construction projects are important for the growth of historic businesses; however, they can lead to frustration if the appropriate concerns are not kept at the forefront of your managers and architects. At Integrity Building Group we pride ourselves on the details and the ability to communicate the proper steps to a successful project.

Belle Isle Conservancy

The mission of the Belle Isle Conservancy is to protect, preserve, restore and enhance the natural environment, historic structures and unique character of Belle Isle as a public park for the enjoyment of all – now and forever.

Formed in the fall of 2011, through a merger of four existing nonprofits – Friends of Belle Isle, Belle Isle Botanical Society, Belle Isle Women’s Committee and Friends of the Belle Isle Aquarium — the new Conservancy, in partnership with the City of Detroit, will bring more private and public resources to our beautiful island park.

Archdiocese of Detroit

The diocese of Detroit was established by Pope Gregory XVI in 1833, more than 100 years after French settlers built their first church here. At the time, the diocese included all of Michigan, Wisconsin, Minnesota and portions of the Dakotas, east of the Mississippi River.

The diocese predates even the state of Michigan, which did not join the union until 1837. At that time, the boundaries of the diocese were changed to fit into Michigan’s newly-established borders.

Christ Church

Ste. Anne de Detroit Church was the first church built by settlers in 1701. The church served as the diocese’s first cathedral from 1833 to 1848.

In 1937, Detroit was elevated to an archdiocese and His Eminence, Edward Mooney was named as our first archbishop. In the following decades the region’s population grew steadily, which required the expansion of many parishes under Mooney.

Today, the Archdiocese of Detroit comprises the six counties of southeast Michigan—Lapeer, Macomb, Monroe, Oakland, St. Clair and Wayne.

Michigan Historic Preservation Network (MHPN)

Founded in 1981, the Michigan Historic Preservation Network is the largest membership organization in the state dedicated to recognizing and preserving Michigan’s rich cultural and architectural heritage.

The founders saw a need for a nonprofit organization that fostered the protection of the state’s irreplaceable historic buildings, structures, sites, objects, features, and open spaces. They saw the benefits of informing others that these were community assets appropriate for continued use or creative adaptive reuse. They wanted to give recognition to successful preservation projects and coordinate and publicize efforts across the state.

Most of all, they wanted to share their experience and expertise with others.

Construction Association of Michigan (CAM)
