About Us
At RENAOS, we are more than just a construction company; we are your partners in transforming ideas into reality. Founded by multi-national engineers with a wealth of international experience, we are based in the vibrant city of Antalya, Turkey, and are dedicated to delivering fit-out solutions and consultancy services that meet and exceed global standards.
Our vision is simple yet ambitious: to produce high-quality products at competitive prices that are not only suitable for the international market but also reflect our commitment to excellence. We believe that every project is unique, and our mission is to provide tailored solutions that cater to the individual needs and preferences of our clients.

What We Do?
Our unique approach to construction sets us apart. We begin by engaging closely with our clients, listening to their ideas and requirements. Using advanced 3D visualization, we present design concepts and iterate until we receive client approval. From there, we proceed to detailed plans, sections, and production drawings, ensuring that every aspect is meticulously planned.
Once the production stage commences, our stringent quality control process comes into play. We monitor every step of production, from materials procurement to the final product. Our commitment extends to packing, transportation, and on-site installation, where our experienced site supervisors and workers ensure seamless execution.
Our approach is to satisfy our customers and establish long-term partnerships.
