REBECCA COFFMAN Architecture, RC|A, practices an integrated, multidisciplinary process to reach design solutions that support a green building agenda. Our background in both architecture and landscape architecture greatly benefits the design process and leads to a graceful interface of structure and site. RC|A believes in a fundamental sense of wellbeing that occurs when design is respectful of its particular place.

At RC|A we introduce architecturally designed elements throughout our projects to bring forth beauty and a sense of quality. RC|A enjoys designing for metal, glass, concrete, stone and wood, interpreting raw materials in unique ways. We work with artists and fabricators and clients are encouraged to get involved in the design evolution.

When climatic conditions are favorable, we look for opportunity to create outdoor spaces that support a variety of public and private activities. We focus our attention on the interface between structure and site and investigate opportunities to gracefully satisfy programmatic needs inside-out.


REBECCA COFFMAN Architecture has developed a broad portfolio of completed projects since it’s founding in 1998.

RC|A works with owners, developers, non-profits, schools, religious institutions, businesses, cities and counties to help design and actuate a wide variety of projects. Our services include:

  • Conceptual Design
  • Community & Master Planning
  • Architectural Building Design
  • Comprehensive Site & Landscape Design
  • Facilities Assessment & Renovation
  • Environmental Restoration

Our office is well versed in helping clients evaluate how and where architectural services are most efficiently rendered. We do our best work when brought into a project at the beginning, either as the primary consultant or as part of a multidisciplinary team committed to reaching an integrated design solution.
