Steel Cantilever Car Shed Design

I want to cover a single parking bay with a cantilevered shed that attaches directly to an existing wall, leaving the driveway completely column-free. The clear footprint is 7 m long by 2.3 m wide, with enough headroom for a standard SUV.

The structure must be an all-steel truss system, fixed to the wall and balanced so the load is safely transferred without front supports. For the roof, specify light-gauge metal sheets and show the fixing pattern, flashing, and any required gutter line.

Please size every member, specify grade and coating, and verify wind and live loads to a recognised code. I also need anchorage details—bolt type, edge distances, and any plate stiffeners—so a fabricator can build exactly what you draw.

Deliverables
• General arrangement and section drawings (PDF + DWG)
• Detailed shop drawings with cut lengths, plate dimensions, and hole schedules
• Structural calculation report with load cases and safety checks
• Bill of materials and brief installation guideline

Native design files from STAAD, SAP2000, Tekla, or similar are welcome alongside the PDFs. If anything is unclear about the site or wall construction, let me know early so we can lock it down and keep the turnaround to about a week.
