O-Kart D Farmer’s Market is the centerpiece of a new civic development in Klong Kuen, Chachoengsao, Thailand. Initiated by the Chachoengsao Development Foundation (CDF), the project is a collaborative effort between public and private institutions—including CJ More, Rajabhat Rajanagarindra University, King Mongkut's Institute of Technology Ladkrabang, and the Sothon Heart Foundation. The initiative aims to cultivate a sustainable, self-sufficient local community through education, agricultural innovation, and accessible public spaces. One of the program’s core missions is to revive interest in the region’s prized produce—particularly the "three-water mangoes"—through learning, cultivation, and marketplace integration.

The complex is organized into three key zones across five buildings. The first zone includes the Fruit Lab, Glasshouse, and Eatery, three pavilions arranged around a trapezoidal courtyard that serves as a welcoming forecourt to the site. The heart of the project is the Farmer’s Market, centrally located to generate a sequence of functional courtyards that facilitate community interaction, trade, and educational events. The final zone is anchored by CJ More, a retail space positioned at the terminus of the circulation route, acting as the project's commercial draw.

Architecturally, the project embraces a dialogue between innovation and tradition. A material palette of black steel and corrugated metalsheet contrasts with warm brickwork, symbolizing the merging of technology and local heritage. The Farmer’s Market exemplifies this synthesis: its 10.8-meter curved ribbed metalsheet roof creates a column-free interior space—ideal for flexible vendor arrangements—while remaining cost-effective and rapid to construct. The market's base is formed by a rhythmic pattern of brick fins, each defining a 2×2-meter module for vendors. At either end, gently arched brick façades face the public road, establishing a bold and memorable identity for the complex. Through a sensitive balance of tradition and modernity, the complex becomes both a symbol of local pride and a platform for sustainable development.”
