In the mountainous regions of Colombia, where elevations exceed 3,000 meters, rural communities face challenges such as harsh climates, limited infrastructure, and economic pressures that often lead to urban migration.

By Fernando Sebastian Contreras Rodriguez - Estacion Espacial Arquitectos SAS, Barichara, Colombia; Carlos Hernan Betancourt Niño, Aldo Marcelo Hurtado Mora - Espacio Colectivo Arquitectos SAS, Cali, Colombia and

To address these issues, the Vernacular Greenhouse project presents an innovative housing model that integrates traditional design with sustainable practices. This approach aims to provide farmers with energy-efficient, self-sustaining homes that support both living and agricultural activities, thereby enhancing livelihoods and encouraging residents to remain in their communities.

Project Summary

A Sustainable Vision for High-Altitude Rural Living

This project reimagines rural housing for Colombian farmers living above 3,000 metres, where extreme conditions demand new solutions. By fusing vernacular architecture with sustainable innovation, the design aspires to support resilient, self-sufficient lifestyles that integrate food production, energy independence, and environmental stewardship.

Productive space.

Adaptive Design for Cold-Climate Agriculture

The residence consists of an inner timber volume for living and a translucent polycarbonate envelope that acts as a second skin—forming a greenhouse that improves thermal insulation and enables year-round crop cultivation. Designed for flexibility, the prototype can be built in various sizes to suit different household needs. It is fully off-grid, powered by solar energy, with systems in place to reuse greywater, collect rainwater, and compost organic waste to nourish crops.

Jury Appraisal

The jury was impressed by this smart, energy-efficient housing concept designed for Colombian farmers living at high altitude. With its iconic geometry and compelling spatial logic, the project offers a sustainable and affordable model that blends domestic life with agricultural activity—fostering a stronger connection to place and community. The design’s ability to connect people with nature in a region known for its harsh climate was seen as a key strength, contributing to a renewed sense of belonging and resilience.

Construction.

The building’s translucent polycarbonate shell creates a multifunctional buffer zone that enhances thermal performance, provides an enclosed semi-outdoor space, and enables year-round vegetable cultivation. The jury commended the simplicity and affordability of the materials and construction techniques, which result in a distinctive architecture that is both pragmatic and aspirational. A powerful example of how rural housing can simultaneously elevate living standards, reduce energy demand, and celebrate local identity.

Statements on Sustainability & Emissions

  • Designed as a self-sufficient rural habitat, the project integrates food, energy, and economic productivity into one architectural system. A greenhouse orchard regulates temperature and provides year-round food for a farming family, using composted organic waste as natural fertiliser—closing the loop with zero environmental impact. A solar farm supplies off-grid energy, supporting independence in remote areas. Inside, flexible spaces accommodate the daily rhythms of rural life and can expand to host tourists seeking an immersive agricultural experience.

  • The house celebrates sensory engagement with local materials—moderating temperature, absorbing sound, filtering light, and connecting with cultural traditions. Its efficient, envelope-style construction reduces joints, simplifies assembly, and minimises labour, transportation, and material costs. The structure is designed for progressive growth: modular units and a beam-supported second level allow the home to expand from 60m² to over 90m² as the family’s needs evolve.

  • In this high-altitude context, the geography dictates the form. The greenhouse is oriented for optimal solar exposure, rising lightly from the land to preserve topography and reduce the need for heavy foundations. Prefabricated structural elements ensure accessibility and speed of construction, while elevated design and natural ventilation strategies maintain thermal efficiency. The result is a house that is both rooted in its environment and carefully attuned to its ecological footprint—designed as an architectural section in harmony with the land.

  • The Vernacular Greenhouse prototype in Colombia focuses on minimising environmental impact through efficient, low-carbon construction strategies. Designed as a prefabricated structure, the project relies on assembly rather than conventional construction—significantly reducing on-site activity and material waste. As a roof-led design, the prefabricated canopy becomes the defining architectural element, enabling a reduction of up to 80% in ground disturbance and construction-related emissions.

    Interior partitions use dry, elementary construction techniques and can be adapted to locally available materials, enhancing flexibility and sustainability. Passive bioclimatic design plays a critical role: the terraced greenhouse effect captures solar heat, while the building’s layout and materials retain warmth through thermal inertia and spatial compartmentalisation—eliminating the need for mechanical heating and reducing overall energy demand.
