Architecture Firm in Atlanta

Treanor’s architecture firm in Atlanta is a vital part of our national practice, blending regional insight with design leadership across a variety of project types. With a strong focus on housing, justice architecture, historic preservation, and site planning, this office plays a critical role in delivering thoughtful, human-centered spaces across the Southeast and beyond.

As one of the most trusted architecture firms in Atlanta, our multidisciplinary team is committed to designing environments that uplift communities, preserve cultural legacies, and support meaningful experiences.

Greek housing and residential design: elevating campus communities

Our Atlanta office is home to a talented group of Greek housing architects who specialize in designing sorority and fraternity houses that foster connection, tradition, and a sense of home. With deep experience in Greek housing nationwide, our architects understand the balance of legacy and lifestyle that defines these unique residential communities.

Whether it’s a new chapter facility or the restoration of a historic house, Treanor designs spaces that reflect the values of each organization while meeting the needs of today’s students. Our projects often incorporate shared gathering spaces, private rooms, accessible design features, and sustainable materials—all while preserving a strong architectural identity that ties into campus culture.

In addition to Greek housing, our team works on a variety of residential typologies including student apartments and mixed-use housing developments. Each design is tailored to enhance comfort, promote community, and reflect the surrounding environment.

Justice architecture: supporting safety, equity, and rehabilitation

Treanor is a national leader in justice architecture, and our Atlanta-based team brings this expertise to communities throughout the Southeast. We work closely with clients to design court facilities, detention centers, public safety campuses, and behavioral health justice projects that are responsive, secure, and centered on dignity.

Our approach integrates evidence-based design, trauma-informed planning, and operational efficiency. Each justice project is shaped by community goals, stakeholder input, and an understanding of how architecture can support rehabilitation and long-term public safety.

As a trusted partner in justice architecture, the Atlanta team supports agencies at the state and local levels in creating facilities that serve people with respect—whether they are staff, visitors, or individuals in custody.

Historic preservation: protecting Atlanta’s cultural identity through design

Treanor’s Atlanta office includes experienced historic preservation architects dedicated to safeguarding the region’s architectural heritage. We approach preservation as both an art and a science—combining technical expertise, historical research, and a commitment to sustainability to give older buildings new life.

Our team has worked on a wide range of preservation projects including historic housing, civic buildings, campus structures, and adaptive reuse developments. Whether preserving a historic Greek house or repurposing a legacy structure for a new use, we honor original materials, context, and craftsmanship while ensuring compliance with preservation standards.

In a city as historically rich as Atlanta, our preservation work reflects a deep respect for the past—paired with a forward-thinking approach that embraces innovation and community resilience.

Site planning: connecting buildings to context

A critical component of our Atlanta practice is site planning, led by a team of skilled professionals in civil engineering and landscape architecture. These experts collaborate with our architects to ensure every project responds holistically to its environment—both natural and built.

From campus housing developments to justice campuses and historic properties, our site planning team designs outdoor spaces, infrastructure, and land systems that support function, beauty, and long-term resilience. Their work includes grading and drainage, stormwater management, ADA accessibility, parking, and outdoor gathering areas—all tailored to the context of the site.

Great architecture starts with a well-planned site, and Treanor’s Atlanta team ensures the foundation is as strong as the structures we design.
