About

We are architects and designers dedicated to creating meaningful spaces that foster connection and a true sense of place. 

Based in Washington, DC, and founded by Katie Selis, Selis Studio Architecture specializes in residential, commercial, and educational projects. We approach each design challenge—regardless of budget or scale—as an opportunity to engage critically with place, history, sustainability, and context.

Through a collaborative process, we center the end-user to deliver thoughtful, innovative, and enduring spaces. Whether reimagining an existing space or creating something new, we bring creativity and purpose to every project.
