Residential Structural Drawings Needed

I need detailed structural drawings for a 60-70 square meters residential building. The drawings required include:
- Foundation/structural drawings
- Floor Plans
- Roof Structure
- Plumbing and Electrical Drawings

I have some existing detailed drawings as reference, but they need a very little bit of intervention.

Ideal Skills and Experience:
- Expertise in residential structural design
- Proficiency in interpreting and completing incomplete blueprints
- Strong attention to detail
- Experience with foundation, floor plans, and roof structure designs
- Knowledge of local building codes and regulations

Please ensure accuracy and compliance with all relevant standards.
