We provide project assistance and consulting beyond the design phase. The services below provide a glimpse into the value of working with us.


Our passion for function and aesthetics is one of the reasons customers prefer our architectural services. Good design is the art of balancing function with relationship, composition, edges, and space and light. All these items are critically important as well as being responsive to your clients’ needs. Our Registered Architects Joseph P. O’Donnell and Roger B. Langer Jr. provide their expertise to make projects of any scope a successful conformation of good design and satisfied clients. Many establishments in our community and throughout western New York are the result of Joe and Roger’s vision and practical expertise.

Space Planning

Architectural designs that account for interior and exterior planning of spaces not only serve those who interact with the structures, but also the environment in which the structure is integrated. Helping our clients prepare an accurate program of the spatial and adjacency requirements of their building is a key component to our success. Our architectural team are experts in space planning to help ensure the optimal result.

Construction Administration

Construction is a multi-faceted mission. Understanding its intricacies and their effect on bringing architectural concepts to fruition is imperative. With over 60 years combined experience in assisting with construction administration, real value engineering, and a keen eye for evaluating construction techniques our team can help ensure that the vision becomes reality with minimal rework, time and costs.

Development Consulting

Our expertise extends well beyond the design and implementation of complex structures. Our team can provide the consulting services at any point in the life of a project, from concept to post-occupancy analysis. We specialize in evaluating properties with the keen vision required to bring large scale development projects to life in a practical and cost-effective manner. Based on information gathered from the local municipalities, and the ability to navigate their regulatory requirements, we can provide clients with preliminary site layouts to maximize the development and to help determine a project’s viability.

Facilities Analysis

The review of a property to determine its short and long-term physical needs is an extremely valuable tool for a building owner, management team and potential buyer. GLA will provide you with a greater understanding within these areas: capital planning and capital improvement opportunities, management practices toward development-based capital planning, produce data on green opportunities to improve energy efficiency and measure the impact of annual appropriations on the physical needs of the property.

3D Renderings

By using advanced 3D applications, we can provide our customers with realistic imagery that bring ideas and designs to life and offer our clients the ability to make important decisions throughout the entire design process. Both exterior & interior perspectives give the ability to better visualize a space such as entry lobbies/features, conference rooms, apartment units, guest suites, bars, restaurants, building elevations, façade renovations and details, etc. We have the in-house capability to offer 3D Digital Building Information Modeling (BIM). Using single source BIM a virtual visual representation of your building is created, facilitating improved coordination between structural, plumbing, mechanical, and electrical components. All the detailed project information is on the construction documents, therefore saving time and money through improved productivity during construction and fewer change orders or requests for information.
