Factories are designed for production. They are rarely designed for everything that quietly makes production possible.

Three years after completing an earlier production building for Shamim Polymer Factory, Davood Boroojeni Office returned to the site expecting to evaluate a finished project. Instead, they found a building that had continued to evolve through everyday use. Workers had established routines that no drawing had anticipated. Informal gathering places had emerged, circulation had subtly shifted, and overlooked spaces had acquired new roles in the factory's daily life.

Rather than treating these changes as deviations from the original design, the architects saw them as a form of knowledge.

The Process Department was conceived from that experience.

Instead of introducing a new formal concept, the project began by asking what architecture could learn from a building already occupied. The result is an industrial facility shaped not only by technical requirements but also by the everyday realities of work that conventional planning often leaves unaddressed.

Production remains the building's primary purpose, but the project recognizes that factories operate through more than machinery, logistics, and efficiency. They are sustained by observation, maintenance, informal conversations, moments of pause, and routines that develop gradually over time. These activities are rarely represented in architectural drawings, yet they continuously shape the workplace.

The design responds by making room for these overlooked conditions without turning them into architectural spectacle.

One observation concerned a place almost every factory has, but almost no architect designs: the smoking area. Instead of remaining an improvised space beyond the building, it became a transparent room integrated into the architectural composition. Visually connected to the production floor while environmentally separated, the space acknowledges an existing routine rather than attempting to eliminate or disguise it.

Another observation was equally ordinary. During repeated visits, the architects noticed workers caring for domestic birds within the factory grounds. Rather than erasing this informal practice in pursuit of a cleaner industrial image, the project chose to accommodate it. A modest enclosure became part of the new building—not as a symbolic gesture, but as recognition that workplaces are shaped by everyday relationships that extend beyond production itself.

These interventions are intentionally quiet. They do not seek to redefine industrial architecture through expressive form or iconic imagery. Instead, they emerge from sustained attention to how people actually inhabit their working environment.

This same attitude informed the building's material strategy. Materials were selected with the expectation that they would record use, weather naturally, and adapt over time. Rather than resisting change, the building accepts occupation as an ongoing condition.

Completion is understood not as the end of the architectural process, but as the moment when the building begins its life with its users.

The project also reconsiders the role of the architect. Instead of assuming that every future condition can be anticipated during design, it acknowledges that buildings continue to evolve after construction. Returning to observe that evolution becomes part of the design process itself.

Only then does the project's title reveal its meaning.

Error Form does not refer to a flaw in construction or a formal irregularity. It describes the distance between architectural intention and lived reality. Every occupied building develops patterns of use that exceed its drawings. Rather than correcting those differences, the Process Department treats them as an opportunity to learn.

The project does not propose a new industrial typology. It proposes a different way of practicing architecture—one that considers observation as important as design, and returning as important as completion.

Buildings are often described as finished objects.

The Process Department suggests something different: the most valuable part of a building may be the life that quietly reshapes it after construction has ended.
