Your Partners in the Process

Developing distinct and creative solutions for our clients.



Formed in 1977, O’Neil & Manion Architects P.A. is an innovative team of experienced architects, located in Bethesda, Maryland, who bring diverse skills and experience to each project.  Our goal is to serve our client.  We are collaborative problem solvers and project team leaders.  Our project experience ranges from custom and embassy residences to larger scale hospitality projects and research laboratory facilities. 

We have established long-term relationships with a broad range of consultants and specialists.  For each project, we assemble the appropriate team.  This allows us to efficiently engage in projects both large and small.  Our services range from strategy, planning and interiors to complete design services including construction administration.

We begin our creative efforts by carefully listening.  We research with our clients to fully understand their projects.  Collaboratively, we define the goals that need to be achieved for a successful project.  Mutually established objectives allow us to efficiently direct our work. 

We understand that design can create value, and the importance of energy conservation and sustainability.  We strive to provide designs that satisfy our client’s needs. 

We use BIM (building information modeling) technology to efficiently explore design options, and to effectively communicate designs.
