Architects and engineers, architecture and structure have symbiotic relationships. Both design disciplines reside in our office starting from the principals down. These practice elements become exposed in our design, not hidden. This creates a rich design unique to every space we create.




All projects start with loose ideas. It may be a sketch on a napkin, a photo from a magazine or a simple thought. Resolving those concepts into a precise constructible plan is our task.




Architecture is a language. Different styles are different tongues but they all must fall within an established protocol of use, code and physics. Completing the puzzle of how one falls into the other in a unique manner is what makes our jobs so rewarding.




We strive to find new and innovative methods to achieve a unique effect and cost-effective solutions




We realize that every project has a budget. A client's vision has to be constructed using common sense solutions. Creating unique and functional spaces must be realistically achieved and constructed within the client's means.

New construction refers to site preparation for, and construction of, entirely new structures and/or significant extensions to existing structures whether or not the site was previously occupied.


Some of the renovations shown are impressively complex, yet some show little more than a relaxing new color scheme, proving that even modest solutions can have a major impact.

In today's world of building design, the endless variety of project types, materials, and goals can make it easy to become overwhelmed with options. For over a decade, all of us at RGA have worked hard to provide simple, cost effective solutions that deliver an uncompromising richness in aesthetics and innovation. Regardless of the project type, our principals of design are the same. Define the needs, assess the current situation and research and consider alternatives that positively address the first two items. Whether you are looking for a new large Medical Office Building, expanding your existing shop, or are in need of a structural repair or want to improve access, the approach is the same. RGA has the proven experience and expertise to Define, Assess and Create a solution for you.
