The Firm

Heintges Consulting Architects & Engineers P.C. is an award-winning professional firm offering the highest level of expertise in the design and implementation of the building envelope.

Since 1989, Heintges has designed and consulted on more than 150 million square feet of curtain wall and exterior cladding for projects throughout the U.S. and in 24 other countries. We work with visionary architects and owners throughout the world, and have designed and consulted on some of the most prestigious cultural projects in New York City, including the renovation of the United Nations Headquarters, the new Whitney Museum of American Art, Lincoln Center, and the Museum of Modern Art.

Led by Robert Heintges, FAIA, our staff is composed of architects and engineers whose experience encompasses all aspects of the design and construction of custom curtain walls, specialty glazing, opaque cladding systems, exterior stonework, and structural glass. Many of the firm’s senior staff members have taught at the undergraduate and graduate levels at academic institutions including Columbia University, Parsons, Pratt Institute, Harvard, and Rice University.

Heintges has offices in New York and San Francisco. Our main office is located in Manhattan and houses an extensive collection of enclosure material and product samples, including more than 5,000 glass samples, and a library of enclosure-related literature and codes.



Robert Heintges, FAIA, is the founding principal of Heintges, and with more than 40 years of experience, is an internationally recognized authority on the design and implementation of the curtain wall.  Mr. Heintges is a graduate of Rice University and an Adjunct Professor of Architecture at Columbia University’s GSAPP.  He has contributed his extensive knowledge of curtain wall theory and practice, as well as environmentally responsible design, to numerous publications and organizations, and has developed long-standing relationships with many of the world’s greatest architects. 



Areta Pawlynsky, AIA, has overseen complex facades in the United States, Asia, and the Middle East since joining the firm in 1991.  Ms. Pawlynsky is interested in exploring the energy efficiency, technical capabilities, and design potential of cladding materials and systems.  Her work has included the assessment and renovation of historically sensitive facades, as well as the execution of new enclosure walls.  Ms. Pawlynsky holds degrees from University of Illinois and Columbia University in architecture and historic preservation.



John Pachuta, AIA, has been involved with the design and construction of innovative enclosure systems throughout North America and Asia since joining the firm in 1995. His areas of expertise include complex facade geometry, structural glass design, blast mitigation and on-site inspection and testing. He has advised various government agencies on revisions to codes and specifications for enhanced envelope performance. Mr. Pachuta holds degrees in architecture from the University of Virginia and Columbia University where he has served as an Adjunct Associate Professor of Architecture teaching courses in building technology.
