Alagado House by Michel Macedo Arquitetos: A Modern Sanctuary Along the Iguaçu River

A Dialogue Between Architecture and Landscape

Nestled within the lush floodplains of the Salto Caxias hydroelectric reservoir, Alagado House by Michel Macedo Arquitetos is a striking example of how contemporary architecture can harmonize with its natural surroundings. Located in Nova Prata do Iguaçu, this 314-square-meter residence carefully addresses the evolving landscape shaped by hydroelectric development along the Iguaçu River.

As hydroelectric plants transformed the river’s ecosystem over time, large expanses of land were submerged, leading to the rise of tourism centered on leisure and environmental contemplation. Responding thoughtfully to this context, the design of Alagado House positions itself as a positive intervention — a peaceful retreat that both respects and enhances the newly created landscape.

Site Strategy: Embracing Topography and Water

Respecting the mandatory setback from the riverbanks, Alagado House occupies the highest section of its plot. The site’s natural slope is cleverly negotiated through a two-half-level layout:

• The lower half-level embeds a portion of the living area into the terrain, creating a sheltered, protected atmosphere.
• Above, the intimate zones — including bedrooms — are elevated, appearing to float above the landscape, separated from the ground by a subtle visual gap.

This thoughtful split not only preserves the natural gradient but also frames ever-changing vistas of the river, strengthening the home's connection to water and the surrounding Atlantic Forest.

Fluid Access and Spatial Experience

Access to Alagado House offers two distinct experiences:

• A gentle side ramp flows beneath a bold cantilevered volume, linking the street level seamlessly to the riverfront.
• Alternatively, a staircase invites a more formal, intimate entrance typical of traditional homes.

This dual-access system dissolves rigid thresholds, creating a fluid, immersive relationship between architecture and nature.

Modular Precision and Spatial Rhythm

The structural organization of the house is guided by a modular system, allowing a rational and rhythmic arrangement of spaces. Bedrooms line up precisely side-by-side, emphasizing modularity and repetition. This approach optimizes construction methods, favoring industrialized elements and prefabricated components for efficiency and sustainability.

By embracing modular architecture, Michel Macedo Arquitetos delivers a design that is both elegant and environmentally mindful, offering a blueprint for future sustainable housing in similar contexts.

Light, Air, and Environmental Sensibility

Large glazed openings dominate the design, ensuring that natural light floods every room. These openings can be:

• Left completely transparent to embrace the outdoors,
• Shielded with wooden brise-soleils to filter sunlight, or
• Fully closed with external shutters for protection and privacy.

Cross-ventilation is actively promoted through a combination of an internal garden and aligned openings, supporting passive cooling strategies. Such environmental consciousness reinforces the house’s sustainability credentials, providing thermal comfort while minimizing mechanical energy consumption.
