Situated within a long-established residential cluster in Gò Vấp District, the original structure dates back to pre-1975, characterized by a single ground level and a solid concrete roof. Over years of use, the previous owners added a corrugated iron roof to mitigate heat absorption. Despite this addition, the dwelling suffered from significant limitations: a lack of natural light, poor ventilation, and a spatial layout unsuited to modern living standards.
The renovation project aims to serve a family of four. The program prioritizes accessibility for the elderly, placing the grandmother’s bedroom on the ground floor, while the children’s bedrooms are elevated to the first floor. The ground floor design minimizes partitions, allowing natural wind and light to permeate freely through the space.
The core concept revolves around a "double roof" strategy. The design retains the existing corrugated iron roof while introducing a second roof layer positioned one meter below. This creates a substantial ventilation buffer between the two layers. This "roof-on-roof" approach not only reduces direct heat radiation onto the upper bedrooms but also facilitates continuous convective airflow from the front to the back facade, optimizing the microclimate within.
Furthermore, a section of the existing concrete ceiling was carved out to create a central void. This intervention improves natural daylighting for the lower levels and organizes circulation throughout the deep footprint of the house. By employing minimalist yet effective interventions, the project successfully revitalizes the old structure, delivering a living space that is highly adaptive to the tropical urban climate at a cost-effective budget.
