The $2,500 Vernacular Home in Modonpur, Bangladesh, is a sustainable house built with local materials like mud, straw, bamboo, bricks, and tin. Designed for a family of four, it responds to the hot, rainy climate with a raised veranda, steep roof, and cross-ventilated rooms. Clay pots in the tea house façade help cool the air. The home includes bedrooms, a kitchen, a toilet, a cow shed, a future kids’ room, a weaving space, and a street-facing tea shop. “Liter bottles of light” brighten interiors, reflecting local, low-impact design.
