JA is a full-service architecture, interior design, and planning firm.

We design architecture that connects people to place. Our work spans civic landmarks, community libraries, homes, and small urban interventions, all grounded in context, craft, and care for the human experience.

Through interior design, we create environments that invite connection and belonging. Our team provides full-service interior design and FFE expertise for projects of every type and scale, supporting healthy, functional, and enduring spaces.

Every plan begins with a sense of place. Our master planning work weaves together land, ecology, and human experience to create communities that feel grounded, enduring, and uniquely their own.

Every successful project begins with understanding. Through feasibility studies, assessments, and early analyses, we uncover each site’s opportunities and challenges to guide thoughtful, achievable design. 

Preserving the places that tell our shared story is central to our work. Johnston Architects partners with local authorities, preservation boards, and community stakeholders to uphold historic integrity while conserving the natural, cultural, and built environments that define our region. 

Every renovation is an opportunity to reconnect people and place. Our tenant improvement work revitalizes spaces through smart design and sensitive detailing, creating environments that feel fresh, functional, and distinctly their own. 

Our expertise in digital fabrication allows us to create custom installations that bring craft and creativity to any project. From large-scale public artworks to finely detailed interior elements, we design and build pieces that elevate the experience of space. 

At JA, we’ve developed a collection of predesigned homes with plans available for purchase, each rooted in thoughtful design and livable simplicity. We also created the Casita, an interactive software tool that allows clients to design and customize their own ADU.
