Office Renovation 2D Drawings

I need 2D layout drawings for an office fitout/renovation. These drawings are essential for client approval before we can proceed with more detailed drawings required for a building permit application.

The 2D layout drawings should include:
- Room layout, walls, and doors
- Furniture and workstations
- Lighting, power points, plumbing
- Fire sprinklers and mechanical systems in ceilings

I have an existing floor plan, but it may be incomplete or outdated.

Ideal Skills and Experience:
- Proficiency in 2D CAD software
- Experience with office fitout/renovation drawings
- Knowledge of building permit requirements
- Ability to work with existing, potentially inaccurate, floor plans

Please provide a portfolio with similar projects. Thank you!
