Unfinished, abandoned buildings are a hidden source of urban decay in Tehran, weakening spatial quality while consuming environmental and financial resources. Without legal or economic support for renovation, demolition often becomes the default response. Artiman residential building exemplified this challenge: a 15-story structure in a classical style, disconnected from its context, lacking contemporary living standards, and left incomplete for years.
The project reframed this condition not as failure but as an opportunity. The strategy prioritized preserving and enhancing the existing structure rather than replacing it, minimizing resource waste and construction debris while reviving Tehran’s disappearing terrace apartment typology.
Design began by redefining spatial boundaries and reinterpreting the building’s original geometry. The structure was neither discarded nor replicated; it became the foundation for a new spatial order. Layouts were transformed from closed, fragmented spaces into a fluid system, establishing continuity between interior and exterior. Continuous terraces wrap the building as transitional layers, providing urban views, natural light, and cross-ventilation on every floor. Common areas were expanded and diversified to foster social interaction while aligning with contemporary residential standards.
Structurally, three heavy concrete floors were replaced with six lightweight steel floors with elevated ceilings. The core was reinforced to integrate two distinct structural systems. Advanced nonlinear analysis and a precise construction process ensured stability and performance.
The outcome is an 18-story residential complex that transforms an abandoned structure into a sustainable, adaptable, and active component of the urban fabric. Artiman demonstrates that renovation can be a replicable, responsible approach to unfinished buildings, where design, engineering, and urban stewardship replace the costly and wasteful logic of demolition.
