Mário Martins is synonymous with elegant architectural language that integrates contemporary design with the raw beauty of the Algarve. His projects embrace southern Portugal's unique topography, light, and atmosphere, crafting sculptural spaces intimately connected to their surroundings. At the core of his work is a dedication to purity, fluidity, and precision. This article explores three extraordinary residences where OTIIMA’s minimalist window systems enhance the architectural vision: Libre House, Voluta House, and Lioz House. Libre House  Perched atop a gentle slope, Casa Libre epitomizes the dialogue between architecture and nature. Its monolithic white forms contrast with the rugged landscape, creating a visual serenity that extends beyond its physical boundaries. The expansive glass façades dissolve the separation between interior and exterior, framing panoramic views of the Atlantic horizon. Here, ‘liberty’ is a tangible experience of openness, weightlessness, and a deep connection with the surrounding elements.

The essence of the Vision system is the art of framing nature without intrusion. Inspired by Ludwig Mies van der Rohe’s "less is more" philosophy and Le Corbusier’s concept of the horizontal window, Vision transcends conventional boundaries to create a connection between interior and exterior spaces. A Revolution in Minimalist Design  Minimalist architecture is about purity, function, and seamless integration. Vision system sliding windows redefine architectural transparency by eliminating visual obstructions and maximizing natural light. Unlike traditional systems that rely on frames as structural supports, Vision takes a radical approach: glass becomes the self-supporting element, free to slide without dimensional constraints. The result is a panoramic window that dissolves the barriers between solid and void, between built form and nature. The frame no longer dictates design but transforms into a discreet guide, leveling out across the periphery and erasing all intrusive lines. The transition between indoors and outdoors is no longer an interruption but a fluid continuum. Read also- Less Is More: The Path of Minimalism in Architecture
