From ideas to reality.

Gillespie Design Group is an architectural design firm that translates client goals into building realities. Established in 2000, we are a team of dedicated and experienced professionals with architectural, interior design and land planning skills. Our projects represent a wide range of building and construction types, with clients who share a common belief that excellent design creates value for them. Though we routinely serve clients throughout the Chicagoland area, Indiana and Wisconsin, we work on projects in other parts of the United States as well.
“Architectural design is a rational process that ultimately creates value for our clients. It is not, therefore, subject to the whims of moments of inspiration—though they can occur. Rather, it is a thoughtfully considered process that follows a progressive approach striving to comprehend and encompass everything that matters and is relevant to both the project and our client.”
—David Gillespie, founder and president, Gillespie Design Group
