Approximately 85% of Ho Chi Minh City’s population lives in narrow alleys where microclimatic conditions are often limited. LiveOut House is located in a small dead-end alley with restricted airflow, high solar radiation, unstable daylight, and compromised privacy. With only two floors, optimizing natural ventilation and daylight posed a significant challenge. In this context, the project was conceived as an architectural experiment aimed at improving living quality for tropical urban dwellings.

Instead of treating the house as a sealed “box” (a house of live in) where interior spaces are rigidly separated from nature, the project adopts the opposite approach: a house of live out—an open dwelling where light, wind, and greenery permeate the domestic environment. Boundaries between inside and outside are softened through outdoor staircases, inner courtyards, buffer verandas, and a sequence of interconnected voids, creating a continuous “in-and-out” living experience rooted in tropical architectural traditions. Here, occupants can always sense shifting sunlight and the coolness of passing breezes.

The building form is tailored to the constraints of a narrow alley while enhancing microclimatic performance. Unlike typical townhouses with compartmentalized layouts, LiveOut House is organized as an open, unified system that allows airflow, daylight, and visual continuity to move freely throughout. Purposefully arranged voids—from the front yard and courtyard to the skylight and rooftop opening—form “wind corridors” that guide natural ventilation even in dead-end alley conditions.

Operable windows and openings are strategically placed based on CFD airflow analysis and daylight simulations to reduce heat gain, enhance cross ventilation, and maintain soft, comfortable light throughout the day. Vegetation, shading louvers, and a breathable semi-transparent building envelope function as climatic filters, providing shade and privacy. White surfaces are used not only for visual lightness but also for their high solar reflectance, reducing heat absorption and supporting passive cooling.

LiveOut House aspires to carve out new “breathing space” for residents in a densifying tropical city. Though compact, the house feels spacious and airy thanks to its spatial continuity and seamless integration with nature. The project aims to serve as a practical example of improving microclimate and living quality in Vietnamese townhouses, aligned with tropical conditions and the direction of sustainable urban development.
