Willoughby Engineering is a design services firm based in Chicago, Illinois, formed by specialists who previously collaborated on major global buildings and masterplans at leading integrated AE firms. The team later joined a large engineering organization, where they led global building systems and sustainability initiatives, before founding Willoughby Engineering to pursue a more personal, client-focused service model. The firm emphasizes high-performance design in its engineering practice.

Willoughby Engineering uses an integrated design approach spanning MEP/FP, sustainability, building physics, and masterplanning, bringing these considerations into projects early to inform the architectural concept. By blurring traditional silos between architecture and engineering, the firm collaborates with architects and design teams to deliver integrated, high-performance buildings.
