Hayes Large designs exceptional places for learning, wellness and culture. Our offices in Virginia, Maryland and Pennsylvania serve clients throughout the Northeast and Mid-Atlantic.

Since 1922, Hayes Large buildings have earned a reputation for delivering long-term value through flexible planning, cost-effective solutions and sound construction. Today, our architects, engineers and landscape architects are leaders in green, energy-efficient design. They use Building Information Modeling (BIM) to envision and improve outcomes. In a rapidly changing world, we share best practices and innovative technologies that help our clients to better serve their own customers.

We enjoy what we do. Having been entrusted with commissions from education and healthcare systems, cultural institutions, business and government, we have a daily opportunity to help people perform at a higher level by improving their surroundings. We design buildings, but we aim to build lasting trust and relationships.
