Local materials form a climate-responsive house in Bangladesh
It is located in Para Dash, a bamboo village in the province Bangladeshthe Vernacular Home by Xinyun Li explores the responsive climate housing through locally available materials and construction knowledge. Made with use mudstraw, bamboothey were fired locally brickand recovered tin, the two-generation residence incorporates passive environmental strategies, flood resilience and spaces for domestic and economic activities in a compact footprint. All materials are sourced locally and assembled using local techniques, creating a construction system that remains connected to the surrounding ecosystem.
The project is located in Modonpur and is shaped by the environmental, cultural and economic conditions of the village. Rather than introducing an external architectural language, the design extends existing building practices, treating municipal construction as an adaptable system. The house is organized so as to maintain continuity with its context, both in form and spatial arrangement. A raised porch acts as a shaded transitional space, supporting daily activities while elevating the interior above potential flood levels. A steeply pitched roof aligns with the local skyline and facilitates rapid runoff of rainwater.

Closed loop material system updated by Climate and Craft
Construction is entirely based on local knowledge, including bamboo frames, mud wall assembly and roofing methods. This approach ensures that maintenance and repair can be carried out using known techniques and accessible materials. The building functions as a closed-loop system, where components can be returned to the environment or re-integrated into future construction cycles.
Climatic conditions play a central role in the design from architect Xinyun Li. Passive strategies are used to regulate temperature, air flow and daylight without relying on mechanical systems. Each room is oriented to capture prevailing winds independently, allowing for effective cross ventilation. The raised terrace moderates humidity and provides shaded outdoor space, while the high, pitched roof creates a thermal buffer that supports the upward movement of warm air. A ventilated roof cavity further enhances this effect.
Openings at different heights on opposite facades create stack-effect ventilation, allowing warm air to exit from higher points while cooler air enters from below. Along the front of the teapot, built-in clay vessels act as air channels, accelerating the incoming air and reducing the temperature through the Venturi effect. These elements also incorporate locally sourced ceramic techniques into the construction system. Daylighting is addressed with both conventional apertures and low-tech solutions. Recycled plastic bottles filled with water and bleach are integrated into the ceiling, refracting daylight into the interior and providing lighting during daylight hours without electricity.

Multi-layered thresholds organize life, work and commerce
The compact design accommodates a high level of programmatic diversity. Separate sleeping areas are provided for two generations, while communal areas support collective use. A textile workshop is placed on a second-floor balcony adjacent to the younger couple’s room, allowing income-generating activities to remain integrated into domestic life. At the edge of the plot, a small shop and tea house create a threshold between the private courtyard and the public street, supporting economic activity while maintaining a degree of separation.
The design organizes these different functions through a sequence of spatial thresholds, allowing life, work and commerce to coexist within a single footprint. The choice of materials and construction methods foster a circular approach, where resources are locally sourced, minimally processed and can be reused or decomposed naturally.
The project demonstrates how climate adaptation, material efficiency and spatial organization can be addressed through existing construction knowledge, aligning contemporary housing needs with established environmental and cultural practices.
