What Sizemore Group does
Sizemore Group is a 50+ year-old, privately held architecture and planning firm headquartered in Atlanta, Georgia with a regional office in Asheville, North Carolina. It delivers full-service architecture, urban planning, and interior design for government/municipal, higher education, religious, and multi-family residential clients across the Southeastern United States, with occasional national reach (e.g., ULI Hines National Competition). The firm operates three integrated service lines: Architecture (civic, higher education, religious, multi-family housing), Planning (mixed-use town centers, campus master planning, placemaking, community workshops), and Interior Design (space planning, finishes, furniture procurement), supported by sustainable design certification expertise across LEED, WELL Building, and EarthCraft programs. Sizemore Group has delivered notable projects including the WELL Building Gold and LEED Gold-targeted Brookhaven City Centre (mass timber construction, Georgia Carbon Tax Credit registered), the EarthCraft Gold City of East Point City Hall, the LEED Gold Emory Goizueta Business School expansion, and the first LEED-certified residence hall at an HBCU (Spelman College The Suites).
The firm generates revenue through project-based professional services fees, sourced primarily through competitive RFP/bid processes for public-sector work and long-term institutional relationships. Pricing is project-specific, based on scope, complexity, and scale, with no public pricing tiers. The firm employs 101-250 people and is led by CEO William J. de St. Aubin and President Joel Helms (with Lily del C. Berrios as President Emeritus following a 2025 leadership transition). Customer acquisition is sales-led and reputation-driven, leveraging AIA awards, sustainability certifications, and professional network presence (AIA, CNU, APA) rather than active digital marketing. Like other mid-market A&E firms, Sizemore Group operates in a high-trust, relationship-intensive segment where switching costs are elevated by institutional memory and continuity of municipal and university engagements.
