Based in a former beer bottling factory in the Northern Liberties neighborhood of Philadelphia, our firm brings together the experience and talents of diverse professionals in a practice that is dedicated to pushing the field of architecture forward. | Michael Moran

Our work includes programming, planning, and design of new buildings, adaptive reuse, and urban and campus planning, as well as developing performance analysis and prediction tools; building and environmental monitoring; and novel building technologies.

Every project begins with a question. A seed, from which a cycle of inquiry unfolds—each answer sparking the next question, so that any one finished design solution brims with insight and empathy. We work within a culture of continuous discovery, where architecture is not a fixed outcome but an evolving dialogue. Our commitment extends beyond delivering exceptional work; we push the boundaries of practice itself, shaping the future of the built environment with clarity, curiosity, and purpose.

Founded in 1984 by Stephen Kieran and James Timberlake with equal emphasis on research, ecology, history, and aesthetics, our interdisciplinary process inspires creativity and encourages sharing ideas, knowledge, and technique. | Sahar Coston-Hardy

Our Philosophy

Provocation

Provocation is a useful tool: it helps us see the elements of our practice that need changing, while charting a course to a better future. We’ve bent the norms of design and construction—but usefully, to resolve dissonance. How do we recover the embodied energy in a building?  Achieve design elegance and environmental initiative, in less time? To answer, we’ve rethought the fundaments of architectural practice. We’ve reimagined the traditional envelope, pre-fabrication techniques, and designed new tools for sustainable outcomes. And we want to bring the whole field with us.

Research

Design and research are linked inextricably. They enrich one another, an essential pairing in a practice that touches many systems and modes of public life. We’re committed to improving the art, quality, and craft of architecture through research into new materials, processes, and products. We conduct deep investigation during design—infusing the craft with insight, and its outcomes with relevance. Exploratory, empirical, and applied research brings added value to our architectural projects, and allows us to develop new, transformational products and tools for the industry.

Sustainability

A sustainable architecture—building at scale—can be a force for change in ways few other practices can. But current standards result in a checklist approach to environmental design. That’s why we take a holistic view. A pond might be a leisure amenity, a stormwater strategy, and a source of irrigation. In this way, our solutions are more than the sum of their parts, using research to pursue the latest in environmental technology, and to develop our own sustainable methodologies. We understand the need to balance resource conservation, energy efficiency, and environmental stewardship with performance criteria, constructability, and budget.

Our Services

Architecture

Design, innovation, and invention in architecture form our practice. Projects span educational institutions, civic projects, arts and culture venues, governmental buildings, private residences, and more. We also renovate and transform existing structures and bring historic buildings into the modern era.

Research

Research is at the core of our practice and is integral to our work on every project. In addition to deep investigations into site, program, climate, ecology, resources, and environment that are seamlessly integrated into the design phase, research projects can be commissioned by clients for specific applications.

Planning

A fully integrated plan combines strategy with analysis of context to form a flexible spatial, temporal, and fiscal vision for the future. We perform feasibility studies, strategic planning, campus planning, urban design and redevelopment initiatives, and master plans for a diversity of clients, including educational, governmental, and more.


Awards

We have received over 300 design citations in the United States and abroad.
