Residential Building Section Layout with Staircase and Lift CAD Plan

This AutoCAD DWG file contains a detailed residential building section layout with staircase and lift planning for multi-storey housing projects. The drawing includes sectional views labeled Section A, B, C, and D, showing internal room arrangement, floor slab thickness, wall construction, vertical circulation, and service zones. It presents staircases, lift shafts, corridors, wash areas, and living spaces with accurate structural alignment. The approximate building height is 21 meters with 6 floors, standard floor height of 3.5 meters, slab thickness of 150 mm, wall thickness of 230 mm, and overall footprint of about 18 x 14 meters. This file is suitable for architects, civil engineers, and builders involved in residential design and construction planning.

The drawing is prepared with proper scale, dimensions, layer management, and annotation standards for professional CAD use. The sectional views help in understanding vertical planning, staircase connectivity, lift positioning, ventilation spaces, and structural load transfer. It is useful for construction documentation, approval drawings, and design development. With clear measurement markings, sectional detailing, and an organized layout, this DWG file improves workflow efficiency and accuracy in residential building projects.
