The architectural idea relies on eliminating traditional vertical transportation tools such as stairs and elevators, replacing them with a system of ramps that curves around the entire mass in a continuous spiral path. This design approach not only solves the issue of movement but also creates a scenographic experience that the resident experiences while gradually transitioning between the four levels, where the visual perception of the surroundings dynamically and variably forms with each new height angle.
The human experience inside the dwelling moves along an inclined horizontal path that connects different functions without physical interruption. This path starts from the basement, which accommodates the garage, office, and laundry space as a starting point embraced by the ground, gradually elevating the user towards the main floor where the vital spaces of the living room, kitchen, and entertainment area gather, up to the residential suites. This gradual transition gives the internal spaces a sense of lightness and integration, as traditional boundaries between floors fade away, and movement transforms into a tool for connecting daily activities with continuous visual and kinetic flexibility.
The spiral path peaks in its functional and aesthetic nature when opening up to the rooftop garden and panoramic viewing point. The orientation of the external ramp contributes to a vibrant interaction with nature elements, where the architectural masses intersect with the sun's movement and the changing shadows throughout the day, giving the facades a renewed visual rhythm. The space user lives a physical and psychological experience that transports them from relative closure on the lower levels to complete openness to the horizon and the surrounding environment above the surface, fulfilling the owners' fundamental desire to integrate nature as an integral part of the architectural composition of the house.
The building’s envelope transforms into a dynamic element that transcends the structural function to become a tool for scenographic control over light and space. The system of metallic sunbreakers (Brise métallique) forms a translucent membrane that envelops the external ramp system, giving the user a sense of protection while moving without detaching from the surroundings. This physical experience reaches its peak in front of the living room, where this envelope opens automatically like flower petals, allowing for a continuous change in the relationship between inside and outside, creating variable geometric shadows on the internal surfaces affected by the change in the direction of solar radiation throughout the day.
The spatial structure of the dwelling is distributed around the kitchen, which occupies a central position as the core of the architectural composition, serving as a visual and social link between the living room, entertainment area, and pool. This spatial structure enhances social interaction and continuous visual contact between the residents, as spaces flow into each other without solid barriers. This central space also opens up to the surrounding vegetation of the residential complex, integrating the external natural landscape as a living backdrop for daily life inside the house.
The central space features a double height that provides a vertical extension that relieves the sight and integrates with passive environmental solutions ensuring thermal comfort. The natural light coming through skylights and high windows bathes the space in balanced natural light, while the high windows activate the physical "chimney effect" to vent hot air upward, parallel to the cross-ventilation movement that regularly refreshes the dwelling's air. This blend of directed air movement and the infiltration of overhead light leaves a calming psychological effect and deepens the resident's sense of environmental comfort within the architectural space.
The Casa Circular home intelligently redefines the concept of inclusive access, converting it from a mere mechanical adjunct to a continuous spatial loop. By replacing traditional vertical transportation means with an external kinetic ramp, the design succeeds in transforming physical constraints into a flexible spatial narrative. This structure generates an environmental accord between passive thermal physics and a dynamic external envelope, demonstrating the suburban dwelling’s ability to achieve ecological efficiency that fundamentally relies on spatial justice.
However, this curved plan involves a clear functional compromise; the vast space required for the continuation of the ramp becomes the main determinant of the internal space volume. Prioritizing this sequential movement restricts the flexibility of internal partitions and increases the construction costs, raising questions about the feasibility of applying these spatial models in denser cities. Furthermore, the mechanical facade imposes complex maintenance burdens throughout the building's lifecycle, revealing a weakness that ties the lyricism of architecture to the continual performance of mechanical systems.
