Manantial House by Apaloosa Estudio: A Sustainable Courtyard Home in Tuxtla Gutiérrez, Mexico

Designed by Apaloosa Estudio de Arquitectura y Diseño, the Manantial House is a compact, sustainable residence located in Tuxtla Gutiérrez, Chiapas, Mexico. Completed in 2023 and spanning just 119 m², the single-story house embraces vernacular architecture, low-cost construction methods, and bioclimatic design principles to respond thoughtfully to its subtropical environment and the client's limited budget.

Context & Concept: A Light-Filled Sanctuary

Situated on a narrow 10 x 20 meter plot, the Manantial House features a well-balanced residential program that includes three bedrooms, two bathrooms, a living room, kitchen, service patio, and garage. The design focuses on creating a calm, introspective environment that encourages relaxation and reconnection with natural elements.

Central to this approach is the use of endemic materials and a deliberate courtyard typology, which transforms the home into a microclimatic refuge. Natural light is used as a primary design tool, creating dynamic patterns and passive thermal comfort throughout the day.

Construction Strategy: Exposed and Economical

The construction system was guided by the client's need for affordability, speed, and low maintenance. The house is built using alveolar block walls and a Domotej roofing system, a patented self-construction technology developed by the Autonomous University of Chiapas. This modular roofing system allows for lightweight concrete slabs with embedded thermal and acoustic insulation using polystyrene or recycled PET.

What’s notable is that the entire construction process remains exposed, eliminating the possibility of traditional wall slots for utilities. This necessitated a precise, pre-planned layout of ductwork and installations, highlighting the importance of construction logistics in exposed architecture.

Passive and Active Sustainability

Manantial House is designed with bioclimatic sustainability at its core. Passive strategies include the thoughtful orientation of rooms toward the central courtyard, maximizing cross-ventilation and natural lighting while minimizing direct solar gain. This courtyard also functions as a garden and open-air corridor, distributing air and light while creating a connection to nature from all interior spaces.

On the active side, sustainability measures include:

Rainwater harvesting
Redirection of neighboring runoff
Use of local materials and Domotej roofing
Thermal and acoustic insulation via filler blocks

These strategies collectively reduce environmental impact while enhancing indoor comfort in a region known for its heat and humidity.

Spatial Experience and Material Expression

The house’s interior spaces are simple yet expressive, with materials like brick, raw concrete, and wood revealing the structural honesty of the build. The interior palette is warm and earthy, emphasizing natural ventilation, open connections between rooms, and views to planted courtyards from every major space—including the bedrooms and living areas.

The garage is sunken slightly due to a pre-existing site cut, subtly separating it from the domestic space and improving the elevation flow across the site. Structural efficiency was achieved by embedding columns within alveolar blocks and capping the structure with a reinforced upper beam chain that anchors the roofing system.

Manantial House is an architectural response to economic limitations, environmental conditions, and a desire for a simple, breathable, and adaptable home. It stands as a model of affordable bioclimatic housing in Mexico, marrying architectural ingenuity with social responsibility, sustainable technology, and a profound respect for place.
