What Studio Arthur Casas does

Studio Arthur Casas is a privately held architecture and interior design firm founded in 1990 by Arthur Casas in São Paulo, Brazil. The studio delivers bespoke architectural, interior, and urban design services across residential, commercial, hospitality, and mixed-use project typologies for ultra-high-net-worth individuals, luxury hospitality brands, real estate developers (notably Gafisa and JHSF Group), and luxury retail/F&B clients. With offices in São Paulo (headquarters), New York, and Lisbon, the firm has completed 185+ projects across 35+ countries and operates a team of 100+ architects, designers, and urban planners under founder Arthur Casas and four senior partners.

The firm operates a project-based professional services revenue model with custom-quoted fees tied to scope and complexity. Its technology stack is centered on design methodology rather than proprietary software: a proprietary cobogó design system (perforated Brazilian concrete blocks), sustainable and biophilic design practices (FSC-certified wood, prefabricated structures, cross-ventilation), and a "horizontal scale" philosophy spanning furniture to urban planning. The studio extends its brand into adjacent product IP through the +55 Design furniture brand and licensing partnerships with Etel, Studio Objeto, and Herança Cultural, and operates the non-profit IACAI research institute focused on experimental Brazilian construction technology and sustainability.

Go-to-market is sales-led and reputation-driven: the firm acquires work through direct client relationships, industry referrals, earned media in Wallpaper*, Dezeen, Architectural Digest, and Designboom, and a sustained international awards track record (100+ awards including World Architecture Festival, Prix Versailles, Wallpaper* Design Awards, iF Design Award, plus three Michelin Keys in 2025 and Forbes America's Top Hospitality Architects 2026). Ownership remains with the founder and principals; there is no evidence of external investment or parent company control.
