Architecture and structure share a symbiotic relationship, and both disciplines are at the foundation of RGA - from our management to our associates. Rather than being concealed, the interaction of these elements becomes exposed in our design. Honesty and efficiency in architectural and structural expression are values essential to every space we create.




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




Architecture is a language. Individual styles are communicated with uniqueness and variety, but they all must fall within an established protocol of use, code and physics. Providing solutions that translate styles and tastes into cohesive and responsible architecture is a challenge we embrace every day.




We strive to find new and innovative methods to achieve solutions that are unique and cost-effective.




We realize that every project has a budget. A client's vision is best realized when based on sound principles and common sense solutions. The creation of outstanding spaces and solutions 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.
