Sam Gresham Architecture








The firm of Sam Gresham Architect has been creating viable and affordable architectural solutions throughout the Midwest for over Sixteen years.  Principle Sam Gresham AIA is both forward thinking and a creative force within the firm who believes that both functionality and economy can be achieved without compromising quality.  Established in 1999, SGA has successfully completed multi-use facilities, commercial and residential projects in Nebraska, Arkansas, Wyoming, Colorado and Oklahoma.  Our firm prides itself on being creatively driven to solve the questions that any project inevitable presents as well as responsibly efficient in seeing the project through to a successful completion.


SGA’s portfolio of projects is as diverse as the clients we serve.  The team has developed expertise in nearly every type of construction and most commercial programs as well as has one of the largest residential portfolios in the state of Oklahoma.  This combined experience with programming, architectural and landscape design, interior design, restaurant equipment planning, project delivery and coordination sets us apart from most firms in our diversity and range.  Experience working with some of the largest fortune 500 companies to the smallest local restaurateur and most everything in between translates to a proven practical architectural design process that is then tailored to each individual client’s needs.

With over 60 years of combined architecture and construction experience on our team we also believe that SGA is a strong partner in the relationships that we enter into.  Our community partnerships are also important to us and we strive to be an active part of our community.  SGA has been actively involved in the rejuvenation of 23rd street in Oklahoma City as an original member of Uptown 23rd, we have strong ties to the Oklahoma Children’s Theatre Company, and have worked closely with Historic Neighborhood committees as well as the Oklahoma City Historic Preservation Commission throughout Oklahoma City to help preserve our local history while adding to its historic fabric.


Our office is a busy and results drive environment.  We have multiple projects ongoing at all times in every corner of the state of Oklahoma as well as several nationally.  We are careful to choose projects that we feel are appropriate for our office and our work load in order to guarantee quality, efficiency and to keep our firm moving in a positive direction.  SGA is centrally located in Oklahoma City and employs a skilled team of talented individuals.  Together we strive to add both quality and leadership to the practice of  Architecture both locally and nationally.



SGA provides programming, concept design, site planning and full 3D rendering services. The purpose of this phase is to arrive at a suitable and sensitive initial design. The first priority for SGA is to listen to your desires, concerns, and needs as well as to listen “between the lines” for the subtle details. During this phase we discuss the project budget and design extent as well as review these discussions with local authorities and consultants.

SGA develops designs into a set of working drawings and specifications so that construction costing may be finalized and construction of the project initiated. Close attention is paid to details in the design during this phase.  In concert with engineering consultants, we develop the structural and hvac design. SGA reviews all engineering drawings, requesting any necessary changes and ensuring compliance with architectural drawings.

SGA’s historic preservation experience provides you with technical and strategic expertise to promote the viability, reuse and integrity of historic homes and buildings.  Working closely with City and State historic agencies our approach finds practical solutions to real-world problems at historic properties.  SGA has the expertise you need, whether a renovation of an existing historic structure or new construction in a historic district.





Master Planning



SGA has extensive experience in land use, site planning and master planning. We offer Master Planning services which provide a framework for decision making that is sensitive to code, legal, economic, state funding, and political factors. Architecture, landscape, lighting and utility systems are all evaluated. Site plans identify functions, delineate private and public space and provide clarity for both vehicular and pedestrian circulation.
