KieranTimberlake is an internationally renowned architecture, planning, and research firm dedicated to creating beautifully crafted, thoughtfully made architecture holistically integrated to site, program, and people. Since its founding in 1984, KieranTimberlake has produced a diverse body of work for clients drawn to an environmentally ethical and innovative approach to design, ranging from new construction to the renovation and transformation of historic buildings.
The Philadelphia-based practice is defined by a culture of inquiry that prioritizes deep investigation, exploration, and collaboration. This holistic approach resolves often conflicting demands of context, culture, program, cost, and sustainability with distinctive, artful architecture.
The firm’s commitment to research has led to a collaborative, interdisciplinary design process that brings together engineers, consultants, builders, and clients in the search for inventive solutions that push the boundaries of current design and construction processes. An ethic of environmental responsibility and sustainable growth is at the core of creative design solutions that synthesize carbon reduction and energy efficiency with culture, context, architectural aspirations, program, constructability, and budget. The result is resonant and compelling architecture, embodying clients’ vision and positively impacting constituents and communities.

Other recent projects include the new U.S. Embassy in London; Henley Hall, Institute for Energy Efficiency at the University of California, Santa Barbara; and the renewal of Harvard University’s historic River Houses. Current work includes 181 Mercer at New York University, a multi-use high-rise accommodating academic, performing arts, athletics, and residential programs, and additions and renovations to the landmark Folger Shakespeare Library on Capitol Hill in Washington, D.C.
