About the Firm

The alchemy of art, science, analysis, and intuition with regard to the built environment is our core mission. Founded in 1984, KieranTimberlake brings together the experience and talents of nearly 100 professionals of diverse backgrounds and abilities in a practice that is recognized worldwide. Our projects include the programming, planning, and design of new structures as well as the conservation, renovation, and transformation of existing buildings, with special expertise in education, government, arts and culture, civic, and residential projects. Common to all our work is that each project begins with a question and continues its development within a culture of continuous asking, ensuring that design results from deep investigation. KieranTimberlake is committed not only to delivering the highest quality services to our clients, but also to pursuing ideas that push the practice of architecture forward.
