The large flat roof extending east-west forms the project's primary architectural move. Responding to the south-facing slope, mountain views, and client needs, the design integrates light, materials, and climate as fundamental elements. ## Load-Bearing Wall System Lime mortar-clad bearing walls aligned north-south define the house's layout. These walls organize circulation while screening neighboring properties to frame southern views. They also facilitate natural cross-ventilation, ensuring year-round thermal comfort through passive design strategies. ## The Light-Playing Oculus The project's standout feature is a circular roof opening above the main terrace. This off-center truncated cone captures winter sunlight, directing it into living spaces. As sunlight moves throughout the day, the shifting beam creates dynamic spatial relationships, transforming perceptions of time and space. ## Seasonally Responsive Design During summer, the high solar angle contains direct light within the terrace, preventing interior heat gain. Deep perimeter porches provide shaded transitional spaces usable year-round. These features exemplify the project's climate-responsive approach to Mediterranean living. ## Natural Material Palette Stone flooring, timber joinery, brass details, and lime mortar walls emphasize durability and environmental performance. The breathable lime mortar enhances indoor comfort while developing a natural patina over time. Material aging is embraced as part of the building's evolving character. ## Architecture Integrated with Landscape The Mediterranean garden forms an integral part of the design. Featuring native, low-maintenance drought-tolerant plants, the landscape extends the mountainous surroundings into the site. Seasonal changes and vegetation movement create a dynamic experience that evolves alongside the architecture. ## Sources covering this story - https://www.designboom.com/architecture/circular-roof-opening-sunlight-casa-oculo-ohlab-palma/ — --- _Summary written by Brifing from the original reporting.
