Founded in 2005, Ballard + Mensua is a full-service architecture firm known for designing distinctive, deeply personal homes and renovations throughout the Washington, DC metro area and beyond. From phased master plans for growing families to custom retreats on the water or in the mountains, we tailor every project to reflect our clients’ goals, budget, and long-term vision.

We specialize in a uniquely client-centered process that combines the efficiency of design-build with the transparency and checks-and-balances of a traditional architect-contractor relationship. Our early-phase cost studies give clients realistic insight into design and budget before major commitments are made—bridging the gap between dream and delivery.

Our firm stands apart through its commitment to fully integrated project management. Unlike many architects, we bring deep experience not just in design, but also in construction and interior detailing. Our drawings are clear, comprehensive, and actionable—crafted to communicate seamlessly with both clients and contractors. They’re grounded in real-world building experience, which is why our details work, and our projects run smoothly.

Led by Seth Ballard, AIA, NCARB, who brings over 33 years of architectural practice, the firm is built on lasting relationships—with contractors, vendors, engineers, and clients alike. These relationships allow us to take on highly custom work with confidence, creativity, and coordination.

We also offer specialized expertise in historic preservation, yet we’re equally inspired by the freedom and variety of working across styles—from contemporary to Georgian, Colonial to Arts & Crafts. We don’t impose a signature look—we listen, adapt, and design for each client, each site, and each story.
