The Building 147 project emerged from the redesign of a compact commercial–office plot with limited site coverage and a five-story height restriction. The site is located adjacent to the commercial axis of Sattarkhan Street and faces the historic Afif-Abad gardens. The initial architectural proposal—similar to its neighboring structures—featured a fully occupied mass with repetitive floor plans, establishing a spatial condition that was indifferent to the urban fabric and the pedestrian–vehicular experience of the city.

Given the elongated proportions of the site and the pre-constructed skeletal frame, the design challenge centered on deepening the building’s façade and creating a meaningful spatial dialogue with the city and the gardens across the street. To address this, the building’s volume was divided longitudinally into two main segments, allowing for deep terraces to alternate between the eastern and western façades. This strategy not only enhanced the façade’s spatial depth but also introduced a layered and dynamic quality to the massing.

These sectional divisions were framed within continuous white boxes, and by dissolving the rigid horizontal separations between floors inside these frames, the design aimed to generate spatial variability and diverse openings toward the street and the garden beyond. On the uppermost level, the absence of a completed structural frame provided the opportunity for further setbacks and larger semi-open terraces, offering open and transitional spaces for light, air, and interaction.

In terms of tectonic detailing, a seamless, monolithic façade finish was employed to preserve the integrity of the volumetric boxes and their relationship to the garden. The slender vertical proportions of the glazed openings and the main entrance were intentionally designed to depart from conventional floor-to-floor scales, emphasizing verticality and lightness within the overall composition.

Building 147 represents an exploration into redefining the relationship between form, depth, and urban perception within a dense urban context—an attempt to extract spatial and perceptual richness from within the constraints of structure, regulation, and urban adjacency.
