Set within the forested terrain of northern Portugal, Otiima House is a residential project that explores contrasts in mass, material, and spatial experience. Designed as a private family retreat, the dwelling is composed of two distinct volumes: a grounded concrete base and a lighter, elevated structure defined by timber, steel, and expansive glazing. The architecture emphasizes adaptability, allowing spaces to shift in function and atmosphere depending on seasonal and social needs. A defining feature is the extensive horizontal window that frames the surrounding woodland, reinforcing a continuous relationship between interior and landscape. Internally, the house balances openness with intimacy through carefully zoned areas and restrained material palettes. Secondary spaces remain deliberately understated, ensuring the primary living volume retains architectural prominence. The project reflects a broader trajectory in contemporary Portuguese architecture, where modernist principles are reinterpreted through site-sensitive and materially expressive design strategies.

Otiima House is conceived as a carefully choreographed sequence of spatial experiences, where the act of arrival becomes integral to the architectural narrative. The approach through a wooded hillside conceals the structure, delaying comprehension until entry, where the interior abruptly opens toward the landscape. This strategy frames the house not as an isolated object but as a constructed encounter between movement, perception, and environment.

Positioned within a contemporary Portuguese architectural context shaped by figures such as Eduardo Souto de Moura, the project reflects a balance between continuity and reinterpretation. Carvalho Araújo engages with established modernist ideas while adapting them to a site defined by dense vegetation and shifting seasonal conditions. The result is a building that aligns with national architectural discourse while asserting a distinct formal and spatial identity.

The house is structured through a clear duality. A heavy concrete plinth anchors the building to the terrain, establishing a sense of permanence and protection, while an upper volume of timber, steel, and glass introduces lightness and transparency. This composition is articulated through a continuous horizontal opening reminiscent of the ribbon window concept developed by Le Corbusier, here reinterpreted to capture expansive views and diffuse natural light across the interior.

At the core of the house, a double-height living space defines both spatial hierarchy and social function. Despite its scale, the environment achieves a sense of intimacy through warm tonal selections and the integration of organic textures that mirror the surrounding woodland. Furniture arrangements subtly divide the openness into smaller zones, allowing for varied modes of occupation. Artistic elements, including works by Dario Alvarez Basso, are sparingly introduced, reinforcing the primacy of architecture, light, and landscape.

Secondary spaces are deliberately restrained, reinforcing the dominance of the main volume while contributing to a broader experiential richness. The kitchen is positioned out of immediate view, conceived as functional rather than representational, while upper-level bedrooms adopt a more enclosed and material-driven character with exposed steel and timber linings. A detached master suite, connected through a glazed threshold, balances privacy with continuity. Extending beyond the built form, the surrounding grounds incorporate natural and cultivated elements, including water features and gardens, completing a composition that integrates habitation with landscape and seasonal change.
