Skillion Roof Design for 150m²

I need a complete design for a residential skillion roof that will cover a radial floor plan of roughly 150 m². The structure beneath is already laid out, so what I am after are the roof-specific documents: layout drawings, framing details, and the structural calculations that prove the concept.

Material preference is clear—formed metal sheets—so please base the pitch, purlin spacing, and connection details on that choice. Colour is still open; once I see your concept we can decide whether a neutral, earth tone, or something bolder makes the most architectural sense.

For software, I normally review work in DWG or IFC, so AutoCAD, Revit, or any BIM-compatible tool is fine as long as the files export cleanly. Wind and live-load data for my region will be supplied after kickoff; factor that into your sizing and fixings.

Deliverables
• Roof plan and elevations in PDF + DWG
• Framing schedule and member sizes
• Fastening/connection details for metal sheeting
• Brief structural report confirming load compliance

If you have examples of previous skillion or cantilevered metal-roof projects, feel free to share links or screenshots so I can gauge your style. Looking forward to collaborating on an elegant, buildable solution.
