Casa 45, in Loulé, emerges from the composition of pure volumes that explore simple geometry and a direct dialogue with the topography. Orientation drives the generous glazed openings, framing the landscape and flooding the interior with natural light, while cantilevered balconies and shading planes ensure comfort and solar protection. The functional layout clearly separates social and private areas, fostering both openness and intimacy. A minimal and light material palette reinforces the sobriety of the design, allowing the house to root itself elegantly and efficiently in its setting.
