Tatakua House by Rcubo: A Fusion of Tradition and Sustainability

A Modern Interpretation of Traditional Architecture

Tatakua House, designed by Rcubo, is a striking example of sustainable architecture that blends modern design with Paraguay’s vernacular building techniques. Located in Luque, within the metropolitan area of Asunción, the project harmonizes urban and rural elements, creating a unique residential experience.

The name Tatakua, derived from Guarani, means "the cave where fire lives"—a reference to traditional clay ovens that serve as communal gathering spaces. This cultural significance shaped the home’s design, emphasizing warmth, community, and functionality.

Thoughtful Spatial Organization

Designed for a young couple, the house centers around food preparation and communal dining, with a basement accessible from the kitchen for food storage and production. The structure is carefully placed within a 27x14 meter plot, preserving existing trees to enhance natural shading and ventilation.

The layout consists of two primary blocks:

• Private Block (West): Contains bedrooms with built-in closets and strategically placed wet cores that function as thermal buffers.
• Social Block (East): Features an open-plan living area with a kitchen at its heart, extending to an outdoor barbecue space that provides shade and ventilation. A vestibule to the north acts as a thermal antechamber, minimizing solar heat gain.

Sustainable Construction and Material Choices

The house utilizes load-bearing brick masonry, reinforced with concrete beams. Locally sourced materials, such as cement soil walls made from excavated earth, ensure thermal insulation and structural durability. A green roof atop the bedroom block improves natural ventilation and provides a visual connection to the surrounding landscape.

Key sustainable design features include:

• Recycled Glass & Ceramic Chimneys: Embedded into the concrete slab to facilitate hot air expulsion.
• Brick Panels for Passive Cooling: Angled towards prevailing winds to enhance cross-ventilation.
• Vaulted Ceramic Roofs: 7 cm thick reinforced ceramic sheets promote airflow and maintain high ceilings for natural cooling.
• Natural Sealants & Finishes: On-site preparation of lime, sand, and natural paints ensures hygroscopic comfort and air quality.
• Minimal Waste Strategy: Uniform use of brick, cement, and soil for floors, walls, and ceilings reduces construction waste.

Handcrafted Local Elements

The project emphasizes craftsmanship, with bathroom accessories, furniture, and hardware produced by local artisans and independent workshops. This approach not only supports the regional economy but also reinforces the home’s connection to Paraguayan architectural heritage.
