Steel Prefab Family Home Plans

I need a full set of working plans for a steel-framed, factory-built family home that I will erect on-site myself. The layout must include a comfortable living room, the required number of bedrooms, plus a combined kitchen and dining area, all designed as transport-friendly modules that can be bolted together quickly once delivered.

What I’m after is more than a concept sketch. I need shop-ready fabrication drawings, a bill of materials, connection details, and a simple assembly guide so the panels and members slot together correctly when I get them on the ground. A 3D model (SketchUp, Revit, or similar) would be ideal for clash-checking before anything is cut, and basic structural calcs for the steel frame will keep my local engineer happy.

I’ll handle the actual build, so clarity and precision in your documentation are critical. Please show me examples of previous prefab or modular steel work you’ve detailed, outline the software you’ll use, and let me know how quickly you can turn the first draft around.
