any firm, but they choose HLZA, and they stay with us"

Comprehensive Capabilities, Focused Expertise

Howard L. Zimmerman Architects, P.C. (“HLZA”) is a full-service architectural firm that specializes in the interior and exterior restoration, preservation, and alteration of existing buildings. Our team of architects, engineers, technical specialists, and building systems specialists offer particular expertise in the exterior envelope and forensic investigation. 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 restoration is essential not only to “green” sustainability, but also the financial sustainability of every property.

A Long-Term View

HLZA 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 1978 this approach has attracted new clients, earned their trust, and consistently won the firm repeat business from many of New York City’s most well-established real estate firms and families.

Practical Solutions

Howard L. Zimmerman, a native New Yorker from a modest background who founded the firm during some of the City’s darkest economic times in the mid-1970s, prizes the value of taking a practical approach to every project. The reality is that properties have needs that must be addressed, property owners have budgets that must be respected, and the costliest interventions are not necessarily the optimal or practical choice. HLZA has the expertise, experience, and practical sense to advise owners on the best course of action for a given property, and to advise owners on the best alternative course of action when budgetary constraints limit what is financially feasible.

Exceptional Client Service

HLZA solves clients’ problems. We begin by presenting a thorough analysis and evaluation upon which owners can base their construction, restoration, and rehabilitation decisions. Then, once a project plan has been approved, our team takes full responsibility for ensuring that the project is completed on time and within budget. We are committed to providing the highest quality professional architectural and engineering services, and earning our clients’ trust by delivering quantifiable value.
