Market Hall

Brief

Replace an informal market shed with a permanent structure without displacing the trading patterns that already worked.

Problem

Traders needed continuous operation through construction, and any new roof had to outperform the improvised tarpaulin cover it replaced — more shade, more airflow, less noise in the rain.

Spatial Concept

The roof does the architectural work; the plan below stays as loose and adaptable as the market it houses.

Material Strategy

Precast folded-plate concrete roof panels, laterite masonry perimeter, no glazing — the hall is fully open-air at the edges.

Environmental Response

The folded roof section is engineered to accelerate hot air out through ridge openings, and its geometry sheds monsoon rain without gutters.

Outcome

Trader occupancy returned to full within a month of each phase opening — the loose plan meant no one had to change how they worked.
