Residential Structure Approval Report

I require a structural design report for my residential property which will aid in obtaining approval from authorities. The report needs to:
- Focus on foundation and load-bearing walls as well as the roof and attic structures.
- Be prepared and written by an experienced structural engineer or professional with a keen understanding of residential property design.
- Be intricate and detail-oriented.
- Be result-driven in order to speed up the approval process by the relevant authorities.
Ideal skills and experience would be a thorough knowledge of residential structural design, expert understanding of approval processes, and proven experience in preparing successful structural design reports.
