Dyeing Factory, Winding Factory & Office · Dhaka-Comilla Highway, Comilla, Bangladesh · 2017

Industrial architecture in Bangladesh rarely aspires to more than function. Buildings along highway corridors are designed to be seen only from the inside, their exteriors unremarkable to the thousands of vehicles that pass them daily at speed. The Seal Trim dyeing factory on the Dhaka-Comilla Highway takes a different position. Its designers at 23/90 Architects understood that a building visible from a major highway has a single moment to register in the consciousness of a passing driver, and they designed the roofline of the 8,902-square-metre facility accordingly.

The factory roof is a continuous wave, its profile rising and falling across the full length of the building in a series of sharp triangular peaks that read, from the highway, as a dynamic silhouette against the sky. This is not an expensive gesture: the wavy profile is achieved through the repetition of a single structural bay type, its cost comparable to a conventional flat or pitched roof while delivering a visual identity that distinguishes the facility from every other industrial building on the corridor. The wave is designed to be read at speed, its rhythm calibrated to the experience of passing it in a vehicle rather than approaching it on foot.

The main building is raised above its site on a plinth, a deliberate decision that places the factory floor above the level of highway dust and noise. The elevation also creates a meaningful datum between the road and the facility, giving the building a presence in the landscape that a ground-level structure would not achieve. At the base of the plinth, a substantial waterbody wraps the building's front elevation, its surface reflecting the raised mass above. This water is not decorative: it is fed by treated effluent from the factory's ETP, supplemented by harvested rainwater, and serves simultaneously as a grey water reserve for reuse within the facility, a fire safety resource, and an evaporative cooling element for the building's immediate environment. The factory's water is closed-loop by design.

Suspended over the waterbody, a glass-enclosed lounge for foreign clients and buyers sits on a deck above the water's surface, its slender columns rising from the pool and its full-height glazing opening entirely to the waterbody view. For a visitor arriving to inspect the factory's output, the lounge reframes the industrial premise entirely: instead of entering a production facility, they arrive at a space of calm and reflection, the water below and the wavy factory roof overhead. The architecture argues, quietly but confidently, that a textile dyeing factory and a considered client experience are not mutually exclusive.
