The Stonewall Group

What The Stonewall Group does

The Stonewall Group is a national architecture and engineering platform headquartered in Lafayette, Louisiana, that operates as a holding company and growth accelerator for architectural and engineering (A&E) firms across the United States. Founded in 2015 and backed by private equity firm South Oak Capital Partners, the company pursues a buy-and-build strategy, acquiring and partnering with established A&E firms while preserving each acquired firm's local brand, leadership, and client relationships. The platform's core technology is integrated service delivery across architectural design, interior design, landscape architecture, and full engineering, procurement, and construction (EPC) execution, supported by standard industry tools including SOLIDWORKS, Inventor, and Fusion360 for 3D CAD modeling and FEA.

The portfolio comprises ten-plus specialized studios covering distinct verticals and geographies: SKS Studio (hospitality/resort design with offices in Kansas City and Dubai), Practical Engineering Solutions or PES (oil & gas, petrochemical, and industrial EPC, headquartered in Lafayette), AMDG Architects (Grand Rapids, commercial/healthcare/education), KSQ Design (Tulsa and New York, higher education and K-12), AODK (Lakewood and Englewood, sacred spaces and commercial), bld architecture (Patchogue, interior design), ADG Architecture (Fort Myers and Sarasota, civic and educational), Architectural Alliance (Wilmington and Exton, urban infill and historic restoration), and MNK Architects (El Paso). The company employs 70+ professionals across these offices.

Revenue is generated through project-based professional services fees across verticals including luxury hospitality (Four Seasons, Mandarin Oriental, Rosewood, Montage, Kerzner International), higher education (Oral Roberts University, Stony Brook University, Tulsa Public Schools), K-12, faith-based (The Salvation Army), healthcare, oil and gas (Schlumberger), and corporate clients (Westinghouse, Google, Cleveland Browns). The go-to-market model is enterprise field sales with direct client engagement, supplemented by an active M&A advisory pipeline (notably through Generational Group) that sources new studio acquisitions. Pricing is project-specific and quote-based with no public rate cards; debt financing from Capitala Group and continued equity from South Oak Capital Partners fund the inorganic growth strategy.

Core offering

The Stonewall Group is a national architecture and engineering platform that acquires, partners with, and grows architecture and engineering firms across the United States. Through its portfolio of branded studios (e.g., SKS Studio, AMDG Architects, KSQ Design, AODK, bld architecture, ADG Architecture, Architectural Alliance, MNK Architects) and its in-house engineering arm PES (Practical Engineering Solutions), the company delivers architectural design, interior design, landscape architecture, engineering (mechanical, civil, structural, electrical, process), EPC execution, 3D CAD modeling, and construction administration services across higher education, K-12, hospitality, healthcare, faith-based, oil and gas, and corporate sectors.

Product overview

The Stonewall Group (also known as SWG Studios) is a national architecture platform that operates as a holding company and growth accelerator for architectural and engineering firms. Rather than a single unified product, the company maintains a portfolio of distinct studio brands—each operating independently under its own leadership—that collectively provide architecture, interior design, engineering, and construction services. The platform includes: SKS Studio (hospitality/resort design), PES (engineering, procurement, and construction), AMDG Architects (commercial/educational), KSQ Design (higher ed/K-12), AODK (hospitality/commercial), bld architecture (interior design), ADG Architecture (civic/educational), Architectural Alliance (urban/historic), and MNK Architects (Texas-based architecture). Each studio maintains its own brand, client relationships, and design identity while benefiting from Stonewall's national resources, financial backing, and operational support.

Broad incumbents

• Gensler: Gensler is the largest privately held architecture, design, and planning firm in the world, providing architecture, interior design, and consulting services across multiple sectors. Like Stonewall, it serves enterprise hospitality, commercial, and education clients, but at a vastly larger global scale with a fully integrated single-brand model rather than Stonewall's federated studio approach.
• Stantec: Stantec is a publicly traded global engineering, architecture, and environmental consulting firm with a strong consolidation playbook of acquiring smaller A&E firms. It represents the scaled public-market equivalent of Stonewall's buy-and-build strategy, though Stantec is far larger and more diversified across infrastructure, water, and energy.
• AECOM: AECOM is a Fortune 500 infrastructure consulting firm delivering professional services across transportation, buildings, water, energy, and environmental markets. While much larger, AECOM competes for large institutional, hospitality, and energy-related architecture and engineering engagements similar to Stonewall's project portfolio.

Direct peers

• HOK: HOK is a large privately held global architecture, engineering, and planning firm specializing in healthcare, education, sports, and aviation. HOK serves similar enterprise clients (e.g., Cleveland Browns equivalent in NFL/NBA stadium design) and operates a multi-office practice comparable in scope to Stonewall's studio network.
• Perkins&Will: Perkins&Will is a global architecture and design firm focused on healthcare, education, commercial, and civic projects with offices across North America. It is comparable to Stonewall in delivering architecture and interior design services for institutional and enterprise clients, though it operates as a unified single-brand studio network.
• WATG: WATG is a privately held global architecture and design firm renowned for luxury hospitality, resort, and residential projects. It closely parallels SKS Studio's hospitality/resort focus and shares Stonewall's enterprise hospitality client roster including luxury hotel brands.
• CannonDesign: CannonDesign is a privately held architecture, engineering, and design firm with deep higher education, healthcare, and science-focused practice areas. Its diversified multi-discipline offering and educational/healthcare expertise closely match the KSQ, AMDG, and ADG studios within the Stonewall portfolio.
• DLR Group: DLR Group is a 100% employee-owned architecture, engineering, and planning firm delivering integrated design services for civic, education, healthcare, hospitality, and sports markets. It mirrors Stonewall's multi-discipline, multi-office architecture/engineering services model with similar client verticals.

Emerging players

• Little Diversified Architectural Consulting: Little is a mid-sized privately held architecture, engineering, and interior design firm serving commercial, healthcare, and institutional markets. Comparable in size and multi-discipline scope to Stonewall's larger studios, with similar enterprise client base and multi-office operations.
• Mead & Hunt: Mead & Hunt is an employee-owned engineering, architecture, and planning firm specializing in transportation, infrastructure, aviation, and water markets. It represents a comparable mid-sized multi-discipline A&E platform serving institutional and government clients, similar to Stonewall's enterprise/government engagements.
