Abstract :
This design-based research explores the potential of renovating a residential house through the concept of Minimal Intervention, seeking to uncover the hidden beauty that lies within everyday ordinariness. The study began with the observation that the beauty of a home does not always arise from decoration or new construction, but rather from traces of living—the marks of time, use, and personal memory. A beautiful home, therefore, is not one that strives for perfection, but one that truthfully reflects the identity and lifestyle of its inhabitants.
The design process focused on preserving the existing structure while reducing unnecessary extensions and minimizing material use. This approach aimed to achieve functional simplicity and cost efficiency, while maintaining the Spirit of Place through site observation, behavioral study, and the reinterpretation of the house’s inherent qualities. Instead of adding, the process emphasized selective retention—keeping what is essential, removing what is excessive, and transforming what can adapt to new living patterns.
The results reveal that minimal intervention does not mean less meaning; rather, it uncovers an authentic form of beauty—quiet, balanced, and deeply personal. The outcome demonstrates how reduction can create spaces that are calm, humane, and emotionally resonant. Moreover, the research suggests that this approach represents a sustainable design philosophy for contemporary Thai domestic architecture, one that values sufficiency, resource-consciousness, and cultural continuity.
However, such an approach cannot be applied as a fixed formula. Each case depends on its own architectural condition, context of use, and the emotional needs of its inhabitants. True design in this sense must arise from direct engagement with the site, careful observation, and an empathetic dialogue between designer, place, and people.
Objectives :
- To analyze the patterns of extensions and the tendency toward excessive spatial use in Thai residential houses, identifying the physical and behavioral factors that lead to such expansion. This objective aims to understand how the desire for “more space” often results in spatial complexity, material waste, and the loss of the home’s original simplicity.
- To identify spatial and functional components that can be reduced, redefined, or reorganized without compromising the quality of living, comfort, or emotional atmosphere of the inhabitants. The goal is to seek a balance between spatial adequacy and the cultural notion of moderation in Thai living.
- To propose a renovation approach that focuses on reduction and reorganization of existing spaces rather than expansion, emphasizing the efficient use of materials, the preservation of the house’s spirit, and the creation of continuity between old and new areas through simple yet meaningful design gestures.
- To evaluate the outcomes of the design in terms of cost efficiency, functional performance, and user satisfaction, through prototypes or case studies developed under this concept. The evaluation seeks to demonstrate the potential of a “minimal intervention” approach as a sustainable and culturally sensitive design model for Thai residential contexts.
Conceptual Framework :
House of Less explores the potential of designing a home through deliberate reduction—removing what is unnecessary in order to reveal the inherent beauty of the existing structure and the everyday life within it. The concept prioritizes “keeping what matters” rather than adding more, valuing the authenticity of the original space over new construction. It views simplicity not as subtraction, but as a way to restore meaning, balance, and calmness to the home. This approach refle cts a contemporary Thai living culture that embraces sufficiency and genuine living.
Process / Methodology :
This study focuses on exploring and analyzing Thai domestic architecture to develop minimal intervention approaches that reduce space and material usage without compromising the quality of life. The research methodology can be summarized as follows:
- Survey of sample houses– Collect data from various types of residential buildings, including traditional and extended houses, and analyze space usage patterns and unnecessary materials.
- Identification of issues and reducible elements– Separate non-essential components from primary functional areas while considering usability and aesthetic value.
- Design of intervention approaches– Develop prototypes or models emphasizing reduction, reorganization of space, and evaluation of budget efficiency and resident satisfaction.
- Testing and evaluation– Apply the proposed approaches to real sample houses or similar case studies, analyzing their appropriateness and impact on daily living.
- Summary of lessons and recommendations– Assess the effectiveness of the methodology and refine the approach according to the context and homeowners’ needs.

Result / Conclusion :
The study found that applying a minimal intervention design approach in residential renovation can effectively balance aesthetics, functionality, and emotional value. By minimizing unnecessary extensions and using materials in an essential and thoughtful way, the living space regains a sense of authenticity—reflecting the real life and personality of its inhabitants. Preserving the existing structure and spatial character not only reduces cost but also maintains the memory and identity of the place.
The design process revealed that the beauty of ordinariness can emerge through the simplicity of layout, the presence of natural light, and the use of tactile, natural materials. The resulting home is not one that strives for formal perfection, but rather a space of calm, warmth, and genuine connection to the user’s daily life.
Furthermore, the research suggests that the minimal intervention approach can serve as a sustainable design strategy within the Thai domestic context—where simplicity, moderation, and resource-consciousness have become essential values for contemporary living.
