Concrete Exoskeleton Architecture: A Case Study in Urban Hospitality

In the evolving urban fabric of Atlanta, a new architectural landmark demonstrates how structure, materiality, and hospitality can merge into one cohesive design language. Rising within the Old Fourth Ward, this 16-storey hotel and members club presents a striking exterior defined by a criss-crossing concrete exoskeleton that envelops a glass tower. The project sits strategically opposite a historic park and near the BeltLine, a transformed industrial railway that has become one of the city’s most popular public spaces. Its architectural presence blends boldness and refinement, setting a new precedent for hospitality-driven developments in rapidly transforming neighborhoods.

The design is distinguished by its structural clarity and urban responsiveness. The three-storey podium grounds the tower with brickwork referencing Atlanta’s industrial heritage, while outdoor terraces with a swimming pool and garden areas extend the social and recreational functions of the building. Internally, the hotel integrates a curated mix of private and communal spaces—from coworking lounges to fitness areas and atmospheric dining venues—each designed with careful attention to detail, material palette, and the guest experience. Beyond being a hospitality destination, this building reflects how contemporary architecture can activate public edges, reinterpret material traditions, and reshape city identity.

Structural and Material Expression

The concrete diagrid serves as both a visual signature and the primary structural system of the tower. Unlike conventional column-and-beam construction, this approach frees the façade, creating dynamic silhouettes across the guestroom windows. Behind this exoskeleton, a window wall system introduces depth and transparency, allowing the play of light and shadow to animate the elevation throughout the day. At the base, grey brick cladding ties the project to the industrial context of nearby adaptive reuse complexes, reinforcing continuity with Atlanta’s material history while introducing contemporary refinement.

Interior Design and Atmosphere

The interiors are designed with an emphasis on warmth, texture, and layered experiences. Dark slate floors, rich wood paneling, and textured plaster create a subdued yet inviting palette in the lobby. Guests encounter curated artworks, tactile finishes, and a balance of vintage and modern furnishings. The atmosphere shifts across programs: fitness areas use polished concrete and neutral tones, restaurants feature vibrant colors and bold upholstery, while the rooftop lounge embraces retro-inspired chrome and leather. This progression in mood demonstrates how material composition can shape spatial identity and support a diverse hospitality program.

Design Element	Material	Architectural Effect
Exoskeleton	Cast-in-place concrete	Structural support and dynamic façade expression
Podium	Grey brick	Contextual connection to industrial heritage
Lobby	Slate flooring, wood panels, plaster walls	Atmosphere of warmth and intimacy
Rooftop Lounge	Glass blocks, leather, chrome	1970s-inspired retro ambience

Program and Spatial Organization

The spatial configuration balances exclusivity and openness. Members enjoy access to coworking spaces, private lounges, and fitness facilities arranged around exposed concrete columns. Public programs, including multiple restaurants and cafes, extend the social life of the building outward onto terraces and the street. The podium integrates recreational amenities, while the tower above provides guestrooms designed with rich textures and natural tones. This layering of spaces—from private retreats to communal gathering areas—establishes the hotel as both an urban landmark and a social hub.

Architectural Analysis

This project exemplifies the growing role of expressive structural systems in hospitality architecture. The concrete diagrid blurs the line between ornament and necessity, offering both visual identity and engineering efficiency. Its reliance on cast-in-place concrete contrasts with the transparency of the glass wall behind, producing an interplay of solidity and lightness. Materials are employed not as superficial finishes but as integral components of experience: rough brick grounding the structure, warm timber softening interiors, and polished stone adding refinement. This careful negotiation between robustness and intimacy reflects a design logic that situates hospitality architecture as both civic and personal.

Project Importance

The architectural importance of this development lies in how it redefines the hotel typology for urban contexts. Instead of being isolated or anonymous, the structure engages the city through its terraces, material references, and openness to the BeltLine. It teaches architects and designers the value of integrating bold structural expression with sensitive interior design and contextual grounding. The project highlights the potential of hospitality spaces to act as civic anchors that bridge public and private life. In the current architectural climate, where cities are redefining identity through adaptive reuse and new construction, this model demonstrates how material integrity and structural clarity can shape future urban narratives.

✦ ArchUp Editorial Insight

The use of a diagrid exoskeleton as both structure and aesthetic gesture gives this project a distinctive architectural language. The play of concrete against glass and the layering of brick at the base illustrate how materials can narrate both history and innovation. Yet a critical question arises: does the reliance on a monumental exoskeleton risk overshadowing the interior subtleties and urban dialogue? While powerful, such bold structural moves can sometimes dominate rather than integrate. Still, the project succeeds in balancing expressive form with contextual sensitivity, offering a meaningful example of how hospitality architecture can contribute to urban character and future adaptability.

Conclusion

This architectural intervention illustrates the convergence of structural innovation, material integrity, and hospitality design. The project demonstrates how a hotel can transcend its role as accommodation to become a civic and cultural presence. By grounding its podium in industrial brick, lifting its tower with concrete diagonals, and enriching interiors with layered atmospheres, the building communicates both strength and intimacy. Its relevance today lies in how it reimagines hospitality architecture as a generator of social interaction, urban vitality, and architectural experimentation. The lessons it offers—regarding structural honesty, contextual dialogue, and atmospheric richness—resonate beyond Atlanta, pointing toward a broader rethinking of urban hotels as architectural landmarks rather than mere service infrastructures.
