Telhado is an architectural project designed to integrate with its natural environment while addressing specific climatic considerations. Located in Oleiros, the project's design focuses on sustainability and functional living. The structure includes modular components that adapt to both shelter and social interaction needs. Through an innovative approach, Telhado stands out as an example of architecture that harmonizes with its context.

The building features a long, sloped roof which enhances water collection capabilities, effectively utilizing local rainfall while providing passive solar benefits. Encompassing various living spaces, the architecture allows for flexibility through designated cabins that can cater to different functional requirements. This adaptability is a significant aspect of the project, offering occupants the ability to personalize their living environment according to evolving needs.

Sustainable Design Strategies
One of the defining aspects of Telhado is its emphasis on environmental sustainability. The rainwater harvesting system is specifically designed to collect and store up to 32 m² of rainwater, significantly supporting the landscape's ecological health. This system is critical for maintaining the surrounding gardens and reducing dependency on external water sources.

The materials chosen for construction are notable for their environmental compatibility. The use of indigenous wooden beams, galvanized metal sheets, standard plywood boards, V-profile gutters, and reinforced concrete combines durability with reduced ecological impact. The structure's design minimizes the need for extensive foundations and waste, showcasing a commitment to resource efficiency.

Modular Components and Integration
The modular approach enhances both functionality and aesthetics, allowing the design to adapt to various user scenarios. Each individual cabin within the structure provides private spaces while maintaining connectivity to the overall project layout. The open-air arrangement promotes cross ventilation and natural light penetration, resulting in a pleasant living environment.

The terraces incorporated into the design extend living spaces outdoors, facilitating interaction and engagement with the surrounding landscape. This feature not only enhances the architectural experience but also aligns with the project's intention to foster community within its design.

For a comprehensive understanding of the architectural plans and sections, as well as in-depth insights into the design ideas and functional strategies employed in Telhado, readers are encouraged to explore the project's presentation. By examining these elements, one can appreciate the thoughtful integration of architecture with the environment and the innovative approaches to sustainable living.
