KlingStubbins was an architectural, engineering, interior, and planning firm headquartered in Philadelphia, with offices in Cambridge, Massachusetts; Raleigh, North Carolina; San Francisco; Washington, D.C.; and Beijing.

[5] The company grew to include engineering, interior design, landscape architecture, and several branch offices in other cities.

Michael Paul Smith, later founder of the popular Elgin Park miniature imaginary village, worked for the company as model maker in the 1970s.

[14] With their Autodesk Headquarters in Waltham, MA, KlingStubbins became the first architectural firm in New England to employ an Integrated Project Delivery (IPD) model.

[15] As opposed to traditional project delivery methods in which a project owner employs an architect/engineering team for design services and a contractor team for building services on separate contracts, IPD requires the owner, architect, and builder to sign a shared contract, expediting the design/building process and sharing both liability and profits among the three parties.
