A Tale of Two Buildings in Nantou: Adaptive Reuse Architecture in Practice

Adaptive Reuse and the Evolution of Urban Villages

In the rapidly transforming urban landscapes of cities like Nantou, adaptive reuse architecture has become a pivotal method of preserving the past while accommodating modern needs. A prime example of this can be found in the renovation and extension of two self-built houses in Nantou, designed by the architectural firm fabersociety. Through the adaptive reuse approach, these buildings were not just structurally reinforced, but also redefined in terms of their interaction with their urban environment, all while retaining their historical significance.

The Concept of Adaptive Reuse Architecture

Adaptive reuse refers to the practice of repurposing old buildings for new functions, preserving their historical and architectural integrity while meeting contemporary needs. This approach contrasts with complete demolition and reconstruction, making it a sustainable alternative that reduces waste, preserves cultural heritage, and promotes a more mindful approach to urban development. In the case of NT46 and NT88, two buildings in Nantou, adaptive reuse plays a significant role in their transformation from private residential spaces to public commercial or office spaces.

NT46: Balancing Preservation with Modern Needs

The Challenge of Retaining Identity

NT46 is situated near a busy square in Nantou, offering a rare opportunity for self-expression within the dense, cramped city fabric. However, the challenge for fabersociety was to respect the building’s original identity while adapting it for modern use. The building’s mosaic façade, a defining feature of Nantou’s architecture, was preserved as much as possible. The architects reorganized the building's shape, adding a new platform, reconfiguring the balcony, and opening up new corridor spaces—all without compromising the original aesthetics.

Structural Reinforcement and the Externalized Solution

One of the most notable aspects of this adaptive reuse project is the externalization of structural reinforcement. Buttress columns were added to the façade, reinforcing the building’s structural integrity while forming a new architectural pattern. This "visible reinforcement" not only meets safety standards but also makes the process an integral part of the building's identity, blending old and new seamlessly. The choice to use structural buttressing as a visible element rather than traditional surface-level interventions (such as painting or replacing windows) reflects the building's evolving role in the urban environment.

NT88: Responding to Changing Contexts

The Challenge of Visibility and Transformation

Like NT46, NT88 faced its own set of challenges, primarily stemming from the site’s changing context. Originally designed with an open park in mind, NT88's facade was soon obstructed by a substation, losing its intended prominence. However, this setback led to an innovative approach in how the building would interact with its surroundings. The architects redefined the building's "edge" by introducing a new layer of corridors that not only addressed the need for additional space but also softened the building's interaction with its environment.

The New Facade: Adding Layers and Functionality

To accommodate new functional requirements without altering the building's height, a circular corridor was added around the building. This addition created a new volume and allowed for increased flexibility in the internal layout. The building’s new facade, with horizontally aligned windows, provides ample natural light and opens up new views, creating a dialogue between the interior and exterior that was previously limited.

Incorporating a Shear Wall System

Incorporating a windmill-shaped shear wall system allowed NT88 to withstand the added weight of the new corridors without overwhelming the original structure. This innovative solution preserves the building's existing layout while accommodating new needs, further showcasing the flexibility and sustainability of adaptive reuse architecture.

Structural Reinforcement: The Key to Adaptive Reuse

Both NT46 and NT88 demonstrate the importance of structural reinforcement in adaptive reuse projects. The architects’ decision to externalize the reinforcement not only improved the buildings' safety but also gave them a unique aesthetic identity. By embracing the reinforcement process as a visible feature, the buildings communicate a narrative of transformation, emphasizing the delicate balance between preservation and progress.

The Future of Adaptive Reuse Architecture

The renovations of NT46 and NT88 are a testament to the power of adaptive reuse architecture in shaping the future of urban spaces. By integrating new functionality with historical preservation, these buildings in Nantou reflect the broader evolution of urban villages from marginal to normative spaces. They highlight the importance of respecting both the past and the future, demonstrating how architecture can serve as a bridge between history and contemporary life.

Adaptive reuse is not just a trend; it is a necessity in our increasingly urbanized world. As cities continue to grow, these projects provide valuable lessons on sustainability, heritage preservation, and the dynamic nature of urban architecture.
