The main concern for our client in “Saro Global Hardware” project was providing the ability to change the type and layout of displayed products, based on market needs. Therefore, the main concept of design was creating flexibility, without Harming the original essence and structure of the space. The use of expanded modular grid system in the entire ceiling, not only provides a structure for the moving display walls (screens in different dimensions and directions) and the implementation of flexibility, but also finds a conceptual and visual affinity with the industrial nature of the subject. Extending ceiling concept toward exterior space regulates the disordered urban façade, makes a base for logo installation and more importantly it invites potential customers inside the store. The Modular pattern is emphasized by accommodating utility channels and electrical elements and exhibits itself through revealing the old structure of the ceiling (Brick Jack Arch system). This type of composition enforces the existing nature of the space and it magnifies the beauty of the outdated brick textile by reverse lighting on top of the grid. Placement of the cashier counter, restroom, meeting room, kitchen, and storage in corners of the plan creates maximum room for displaying products, as the main function of the store. In the next step, due to the display nature of the walls adjacent to the entrance, the grid folds on the walls. Thus, the viewer accepts the interior space as a showcase for a store without a window display. Careful execution of designed details, use of exposed structural and mechanical installations, a combination of neutral colors to avoid visual disturbance, and use of linear and regular geometry in the structure of interior elements, all try to create an industrial spatial experience for the audience and to be a worthy sign of the quality of the products within. The accompaniment of a modern modular Grid and a traditional Brick Jack Arch system in addition to enlivening the interior space, also penetrates the public passage and creates contrast in the old context to emphasize the complementary overlap of the industrial layer of the space and the old body of the building.
