1100 Architect

1100 Architect is a New York-based firm that has delivered award-winning projects for clients around the world. Founded in 1983 by David Piscuskas, FAIA, LEED AP, and Juergen Riehm, FAIA, BDA, the studio provides services in architecture, interior design, urban design, and master planning, along with consultation in environmental review, historic landmark assessment, and sustainability planning. The 70-person office works at all scales and across many markets, with a record of built work for educational institutions, local and federal governments, cultural organizations, commercial workplaces, and residential clients.


We are committed to providing the highest level of client services, maintaining clear and consistent communication, proactively anticipating client needs, and endeavoring to make the process of working with us as smooth and efficient as possible. We welcome client input at all stages of a project. As a firm, we are quickly and decisively responsive to our clients, flexibly adjusting our processes to suit each client and project.


Site-specificity is a fundamental tenet of our practice. We design buildings—each one, unique—that are deeply rooted in a sense of place. In ways both quantitative and qualitative, we carefully evaluate each site, resulting in buildings that are intrinsic to their place, environmentally appropriate, and responsive to existing and historical context.


Our studio is known for its meticulous attention to detail, and we apply that rigor to each project we undertake. We believe that materiality is central to the experience of a space, and, with every project, we carefully consider the characteristics of each material we select, creating enduring works of architecture with layered sensory experience.


We design to build. We consider our core client service to include not only design excellence, but also the successful and efficient delivery of completed projects. We partner with our clients throughout the full design and construction process, ensuring the client experience is as seamless as possible.


We are fundamentally committed to sustainable design, both as a matter of energy efficiency and as a concern for the overall wellness of our clients and those who spend time in and around our buildings. Design excellence and environmental sustainability, we believe, are interconnected elements of any project we undertake.
