Our passion drives us to construct a legacy as the leading architectural and engineering firm in New York City.

Comprehensive Capabilities, Focused Expertise

Howard L. Zimmerman Architects & Engineers D.P.C. (HLZAE) is a full-service architectural & engineering firm that specializes in the exterior and interior restoration, preservation, and alteration of existing buildings and their systems. Our team of architects, engineers, technical and building systems specialists offer professional expertise, particularly in exterior envelope, MEP/FP system upgrades, and forensic investigation. For the past 40 years, HLZAE has developed an excellent reputation as the go-to architecture & engineering firm for existing residential, commercial, and institutional properties in the New York City region. We are “an architect’s architect” and take the view that expert restoration is essential not only to environmental sustainability, but also the financial sustainability of each property.

A Long-Term View

HLZAE approaches every new project with the same goals: to protect and enhance the long-term value of the property as efficiently and cost-effectively as possible. Since 1981, HLZAE has utilized this approach to establish trust-based relationships with our clients which has resulted in repeat business from many of New York City’s well-established real estate firms and families and several respected institutions.

Practical Solutions

Howard L. Zimmerman, FAIA, a native New Yorker from a modest background, established his career during some of the City’s darkest economic times in the early-1980s. He prizes the value of taking a practical approach to every project, understanding that properties have needs that must be addressed and budgets that must be respected, and that the most costly interventions are not necessarily the optimal or pragmatic choice. HLZAE has the expertise, experience, and diagnostic sensibilities to advise owners on the best course of action for a given property and to provide alternatives when budgetary constraints limit what is financially feasible.

Exceptional Client Service

We solve our clients’ problems.

We begin by presenting a thorough analysis and evaluation upon which owners can base their construction, restoration, and rehabilitation decisions.

Once a project plan has been approved, our team takes full responsibility to ensure that the project is completed on time and within budget. We are committed to providing the highest quality professional architectural and engineering services and to earning our clients’ trust by delivering quantifiable value.
