Tekfen Construction Office Project has been completed within a short period of three months within the scope of design and built works in its new location within Tekfen Tower in Istanbul / 4. Levent. A dynamic, innovative and modern perspective is adopted in the design. The project has been handled within the context of the physical environment-geometry of the area, technical infrastructure, natural light zone, open office working order-circulation setup and technical decisions that are required to be provided. Although the schedule of construction is a challenging factor for the design team, the focus of design is on establishing the spaces to live a dynamic and social setup. Co-working and open meeting spaces have been added to the design so that employees can have a pleasant time together. The corporate color of the company and the different uses of natural wood can be seen in the entrance and common areas.
