78. Free Download CAD Drawings of Office Building Floor Plans (Level 4 & Level 5)
This free CAD drawing set presents the architectural floor plans of Level 4 and Level 5 of an office building, clearly shown at scale 1/100. It is a useful reference for architects, engineers, and students for study, design development, and construction documentation. The layout is well organized with office rental spaces, a central core including elevators and staircases, male and female restrooms, technical rooms, and air-conditioning service areas.
In addition to the overall floor plans, the package also includes free technical shaft detail drawings (KT-9, KT-10, KT-11, KT-12) at scale 1/25, showing wall build-ups, finishing layers, dimensions, and construction materials. These drawings help improve space coordination, ensure MEP integration, and support accurate on-site execution for office building projects.
I also recommend downloading other Office Building CAD drawings for your project reference.
