Esteturco is an Istanbul-based operation center specializing in health tourism. Upon our initial visit to the site relevant to the design project, we observed significant issues with lighting and noted that the dark colors created a stifling atmosphere for users. The client's expectation from the designer was a compact office accommodating six staff members, one receptionist, and one manager. Additionally, we needed to consider the inclusion of a mini kitchen, filing and storage cabinets, and a cloakroom. Given the space's layout, various niches were designed to enhance the lighting effect within the interior, ensuring the overall composition's coherence. A long table accommodating six employees was placed in the central area, illuminated by a sculptural lighting fixture. A cluster of plants separates the reception desk from the working group behind it.
