120. Free CAD Drawings of the 1st and 3rd Floor Layouts for an 18-Storey Office Building

This CAD drawing set presents the functional floor layout for the 1st and 3rd floors of an 18-storey office building. From the overall plan, the building form is organized with a soft, curved geometry, with a large central hall acting as the core space of the project. The seating arrangement is designed in a semi-circular layout facing the stage, which helps optimize visibility and creates a focused atmosphere for conferences, meetings, or corporate events.

Around the central hall, supporting spaces such as meeting rooms, offices, and service areas are arranged in a clear and logical manner. These rooms are connected through wide corridors that allow smooth circulation between different functional zones. Staircases positioned on both sides of the building provide convenient vertical movement between floors while also ensuring emergency exit routes.

Overall, this drawing offers a clear reference for understanding how space is organized within the building. If you are looking for reference materials for conference halls or event spaces inside office buildings, this CAD file is worth downloading and studying.
