Year Established: 1878

Ballinger was one of the first firms in the country to merge the disciplines of architecture and engineering into a professional practice. Our single office in Philadelphia houses a staff of over 200 people, comprising three architectural studios, two multi-disciplinary engineering studios, and an interiors studio. We endeavor to create buildings that respond to the needs, values, and context of the people who occupy them, and the institutions, cities and landscapes to which they belong. We seek to design enduring buildings of purpose and imagination. We believe in the power of collaboration, and we savor the opportunities to work with clients who share our passion for discovery. Ballinger's interdisciplinary design teams partner with our clients in a patient search to frame a vision for each project - a vision which honors the unique missions, cultures, and imagery of our clients, and aims to inspire the collective team to develop ideas that rise above expectation.
