Casa Cajuí was born from a careful reading of the natural topography and dense forest that surrounds the land in Manaus. The project is based on an understanding of the equatorial climate and the integral preservation of the site, establishing a continuous dialogue between architecture, ventilation, and landscape. Built on the existing slope, the house projects out toward the forest, freeing up the ground and creating a continuous balcony that serves as a contemplative and social space, mediating between interior and exterior. From the entrance, the visual axis crosses the residence to the lake at the bottom of the lot.
Environmental preservation guided all planning decisions. No trees were removed; on the contrary, the existing vegetation defined the zigzag geometry of the project. Trees such as cupuaçu and avocado became structuring elements of the space, requiring precise foundation solutions and cutouts in the roof to ensure the integrity of the roots and crowns.
The social block is protected by a single-slope concrete roof cast in situ, whose thickness ensures high thermal inertia. Its slope follows the prevailing winds, articulating a system of openings that promotes permanent cross ventilation. The elevation of the house and the upper fins of the roof enhance air flow, eliminating the need for air conditioning.
In the intimate block, the roof unfolds in two planes, reinforcing the geometric continuity with the terrain. Permeability is intensified by continuous openings and glass-free brise-type wooden panels, which ensure environmental comfort with constructive simplicity.
The relationship with the ground unfolds in layers: two terraces, internal unevenness that configures an artificial topography, and the accessible roof itself, designed as a path for observing the Amazonian sky. The project is complemented by rainwater harvesting systems and plans for future stages, such as a swimming pool and water reuse. Casa Cajuí synthesizes minimal intervention, climatic performance, and sensitive integration with the Amazonian environment, continuously articulating matter, light, and air.
