Howard L. Zimmerman Architects, P.C. (HLZA) is an architectural and engineering firm that specializes in the exterior restoration, preservation, and alteration of existing buildings, including their mechanical systems. Our team of architects, engineers, technical specialists, and building systems specialists offer particular expertise in the exterior envelope and forensic investigation. In addition, we are also advisors for new construction, applying our years of experience to assist in designing resilient and secure curtain wall applications. Over the past 30 years HLZA has developed an excellent reputation as the “go-to” exterior architecture firm for residential, commercial, and institutional properties in the New York region. We are “an architect’s architect” and take the view that expert exterior architecture and up-to-date mechanical systems are essential not only to “green” sustainability, but also the financial sustainability of every property.
