Second Floor Architectural Plan DWG Staircase Study Room Layout

This second-floor architectural plan DWG file provides a clear and detailed layout of a residential upper floor with a scale of 1 to 100 and overall dimension reference of approximately 17150 mm. The drawing highlights a new staircase proposal integrated into the plan, along with a newly formed study room created from demolished staircases, optimizing space utilization. Existing spaces such as the activity area, bedroom 3, and bedroom 4 are retained without changes, ensuring design continuity. The layout includes circulation paths, room divisions, wall thickness, and door placements for accurate planning and execution. The plan also shows the parking area below alignment reference and structural wall boundaries for construction clarity. Notes specify all dimensions in millimeters and emphasize site verification before execution. This AutoCAD DWG drawing is ideal for architects, interior designers, and engineers for residential planning, renovation, and staircase modification detailing.
