Mariana Orsi Arquitetura + Design

Mariana Orsi Arquitetura + Design is a Brazilian architecture studio focused primarily on residential architecture and interior environments that emphasize spatial clarity, natural materials, and functional simplicity. The studio approaches architecture through the rational use of resources and thoughtful optimization of spatial elements, creating projects that balance efficiency with aesthetic sensitivity. Their work often explores the relationship between interior life and the surrounding environment, allowing architecture to respond naturally to landscape, light, and everyday living patterns.  The firm’s design philosophy is centered on timelessness, material honesty, and human-centered spaces. Projects frequently integrate natural elements such as wood, stone, and exposed concrete, reinforcing a strong connection with nature and creating environments that feel both contemporary and enduring. From compact residential renovations to larger houses and mixed-use spaces, the studio aims to craft architecture that is visually balanced, emotionally engaging, and carefully adapted to the needs of its users.
