Nelligan White Architects PLLC is a New York City firm recognized for pioneering work in energy-conscious and sustainable design. This comprehensive practice of architecture includes new construction, master planning, and the reconstruction and adaptive re-use of historic structures. The firm’s projects range from the design of individual pieces of furniture to institutional projects over 1.2 million square feet. Over the last ten years, Nelligan White has designed and administered construction for projects totaling over a half billion dollars in value. Most of this work has been for educational, institutional and commercial clients.

Organized as a collaborative environment, all members of the team participate in design, technical work, and construction administration. Although the list of residential and commercial projects are extensive, a long-standing commitment to public and cultural work has remained a central part of the practice.

The collaboration of Principals Bruce G. Nelligan and T. Michael White is based on the shared belief that good architecture should enhance the quality of life for the individuals and communities involved. Integral to this belief is the architect’s responsibility to incorporate environmentally sustainable solutions into every aspect of the design process. Educated as modernists, they believe independent research and an in-depth understanding of both modern and traditional building technologies can beneficially inform the contemporary architectural practice.

In their practice, Nelligan White has pioneered the use of twenty-first century techniques and materials in rebuilding and restoring important structures throughout New York City that would otherwise be lost. Their work, shaped by decades of research and historic reconstruction, demonstrates a comprehensive knowledge of building performance and traditional uses of materials. This process involves careful and efficient responses to programmatic, urbanistic, and technical issues with continual participation from the principals throughout all phases of design and construction.

Nelligan White was responsible for the historic preservation and adaptive reuse of three Armories for the New York City Department of Design and Construction: the Bedford-Atlantic Armory, the Park Slope Armory, and the Franklin Armory. Among the firm’s numerous awards for architectural excellence, these projects earned them the Lucy G. Moses preservation award from the New York Landmarks Conservancy. Nelligan Whites’ repertoire demonstrates a capacity to produce work on time and on budget for clients while skillfully developing innovative and environmentally conscious solutions to meet challenging problems.

Our Sustainability Policy

Nelligan White Architects is committed to environmentally sensitive, energy-efficient planning and building design, a dedication that began at the firm’s inception. All work, whether or not specifically designated as “green,” is shaped by the firm’s concern for these issues. The ability to incorporate the many sustainable considerations into building design is the result of decades of hands-on practice, research, and development.

The firm treats energy as the key to sustainability.

Buildings claim up to 40 percent of the United State’s total energy consumption. By focusing on the energy embodied in the materials and used in the processes of constructing and running buildings, we can effectively approach sustainable architecture.

Adapting existing structures is one way this can be accomplished. By extending a building or building component’s life cycle, the less energy, resources, and dollars it will consume. That is why renovating existing libraries and school buildings often includes replacing antiquated systems and materials with high-performance ones.
