Prefab Changeover House: Balancing Architectural Flexibility and Connection with Nature
The Prefab Changeover House is a small red structure resting on a series of sprayed concrete columns, surrounded by forests in Barcelona. This location presents a unique architectural challenge, as it combines the surrounding natural environment with the industrial character of the house, allowing for an exploration of the relationship between the building and its context.
The project faced the challenge of restoring an old, dilapidated wooden house built on nine columns and left to deteriorate in the mountains. Such a situation pushed the architects to rethink strategies for preserving the existing structure rather than opting for complete demolition and rebuilding, with a focus on material sustainability and design flexibility.
The Spanish studio TEST proposed three alternative strategies to address the challenge, providing multiple options for the new owner. After evaluating the choices, a prefabricated modular system placed atop the existing foundations was selected. This approach not only enabled reuse but also enhanced flexibility inside and outside the house, allowing spaces to adapt to the evolving needs of the occupants.

Design and Structural Efficiency
Despite its compact size, the modern house stands out for its high structural efficiency, covering an area of 60 square meters. The house consists of eight balloon-frame units, each measuring 3×3×3 meters, ensuring a consistent and harmonious design.
The units are strategically stacked atop reinforced sprayed concrete columns, minimizing environmental impact on the terrain and allowing the house to rest on nature without harming the surrounding ecosystem. These columns are also equipped with mechanical connectors, facilitating assembly and providing the possibility of future modifications to the house structure if needed.
Integration with the Natural Environment
The architectural team paid special attention to cladding the units with finely textured wood. This choice not only adds aesthetic value but also helps the house blend seamlessly with its surroundings despite its striking red color. The wood acts as a bridge between architectural boldness and the tranquility of the forest, enabling the house to harmonize with the natural landscape.
Through this approach, the house becomes more than just a small structure, it transforms into a harmonious architectural element that enhances the serene environment around it.

Interior Design and Minimalist Style
The interior design of the house reflects a minimalist aesthetic, enhanced with subtle industrial touches that give the space a distinctive character. The design emphasizes flexibility, avoiding rigid programming to provide a versatile living environment. By omitting fixed elements, the space becomes adaptable to changing needs and configurations, accommodating the dynamic lifestyles of its occupants over time.
Connection with Nature and Privacy
The architects also integrated an exterior wooden shell encasing the expansive glazing, granting the house the ability to almost fully open up to its surroundings. This design offers stunning views of the surrounding trees and allows nature to merge with the interior from every angle.
When the occupants desire privacy or a cozy retreat, the house can be fully enclosed, creating an intimate and secluded living space. This dual capability ensures a seamless transition between openness to nature and privacy when needed, enhancing the living experience and making it more flexible and responsive to its environment.

✦ ArchUp Editorial Insight
The Prefab Changeover House can be considered a valuable architectural experiment for studying the adaptation between infrastructure and the natural environment. On the positive side, the project demonstrates how a small house can achieve flexibility in interior use and openness to nature, providing a model for designing adaptable spaces that meet the diverse needs of occupants over time. It also highlights the potential of integrating natural materials, such as wood, into a modular design, enhancing harmony between the building and its natural surroundings.
However, the project raises some reservations related to size limitations and reliance on predefined modular units. Despite its efficiency, the design does not offer fully flexible solutions for all types of use and may face challenges when attempting to expand the space or modify the structure to accommodate different future requirements. Additionally, the extensive openness to nature can present challenges regarding privacy and comfort under varying climatic conditions, requiring careful consideration when applying this concept to other projects.
Overall, the project serves as a practical reference for exploring the balance between flexibility and environment, while emphasizing the need to assess design constraints before expansion or replication in other contexts. It stands as a rich source of insight and inspiration in contemporary architecture.
