2D AutoCAD Floor Plan for 4BHK

I need a detailed and professional 2D AutoCAD floor plan for a 4BHK residential house. The design should include four bedrooms split across multiple floors, a living room, dining area, kitchen, and 3–4 bathrooms. Each room should have accurate dimensions, clearly labeled, and with proper annotations. Door and window placements must be shown, and furniture layout suggestions are welcome (though optional).

The final plan should:
- Adhere to modern residential design standards with a functional and easy-to-navigate layout.
- Include construction-ready details with layers, blocks, and hatching for clarity.
- Optionally, use color coding or pattern hatching to distinguish room types.

Deliverables:
- Editable and precise AutoCAD (.dwg) file.
- Presentable PDF version.

The final output should be professional, precise, and ready for presentation to clients or contractors.
