IRC Cedar Gable Porch Design

I’m building a cedar-framed gable porch that will cover roughly 150-300 sq ft, and I need a licensed structural engineer to take the concept through full IRC compliance. Your task is to size every member—rafters, ridge, beams, posts, connectors—and provide the accompanying load calculations for dead, live, wind and snow forces.

Please prepare a concise calculation package (PDF) and clear construction drawings in CAD or Revit that my builder and local plans examiner can use without further clarification. Indicate all assumptions, reference the relevant IRC sections and include uplift/connection details so we can secure permits on the first submission. A professional seal for my state will be required before final sign-off.
