Building with confidence since 1970.
Founded by İsmet Çelik, Çelik İnşaat is an Istanbul-based construction and real estate company operating in real estate development, superstructure and infrastructure contracting, engineering and turnkey projects.

Engineering expertise and construction experience
Çelik İnşaat’s experience extends from residential and commercial buildings to data centers, industrial facilities and infrastructure projects.
Combining real estate development with construction contracting, the company works on projects with diverse uses and technical requirements. Together with its architecture and engineering services, this experience forms the structure of the company’s operations.
The company’s in-house architecture and engineering teams bring together technical knowledge and site experience. Depending on the scope of the work undertaken, the design, procurement, construction and commissioning stages are carried out under a shared project management approach. Alignment between design decisions and site execution, and coordination across disciplines, form the foundation of this approach.
Çelik İnşaat addresses the technical requirements, functional needs and client expectations of each project together. Structural safety, functionality and architectural quality are at the center of its work. Quality, occupational health and safety and environmental responsibility are integral to its working approach. Time and budget targets are also among the criteria that guide its project management.
