In redesigning the office space for an IT and graphics company, a comprehensive 3D interior design was used, which not only creates modern and creative work areas, but is also thought through down to the smallest detail. From the meticulous presentation of office equipment to the careful selection of lighting, every element in the architectural visualizations was handled with great care. This process included intensive discussions with the customer to develop a deep understanding of their vision and requirements. The modelling of the office and conference rooms was carried out with particular attention to texture, materials and lighting in order to make the rooms not only aesthetically appealing, but also functional and atmospheric. The project highlights the importance of a detailed approach to 3D visualization in order to create a realistic yet inspiring work environment that involves the customer in planning and supports the design process.
