64. Download free layout floor plans of a 12-story office building
Looking at the overall set of drawings, this is clearly a layout design for a 12-story office building, organized in a practical and coherent manner. The two basement levels are mainly arranged for parking, technical rooms, and storage areas. The basement ramp is separated properly, with a reasonable turning radius that ensures smooth two-way traffic flow without conflict.
The ground floor prioritizes the main lobby and service areas. The entrance lobby is spacious, with a transitional space before accessing the vertical core. Restrooms, technical rooms, and emergency staircases are grouped around the central core, allowing the surrounding floor area to remain flexible for open-plan offices or subdivided rental spaces.
The typical office floors follow a clear structural grid with consistent column spacing, making it convenient to arrange open workspaces or partitioned offices depending on tenant requirements. The vertical circulation system, including elevators and staircases, is centrally located to minimize travel distance and meet fire safety standards.
Notably, the surrounding setback and landscape areas are carefully planned, reflecting coordination between architecture and technical infrastructure. This drawing set is highly applicable for medium-scale urban office building projects.
