You copied and pasted that info, which is wonderful but what do you want to discuss about it? Seems weird that you copy and paste very similar topics within a minute of each other.
Basically its something I want to get into so i am willing to do one for free to get the experience and then start a part time business doing it.
All the best.
I design roof trusses mate so if you want I'll do you a cheap price on the materials, you'll just need a chippy to fit them. Do you have any drawings? I guess not seeing as you are looking for some for the building inspector?
Ahh Squeeam you'll need an engineer to spec up the Timbers and other such materials. It's not really the job of an Architectural technician. Are you looking to take the roof off or just convert whats there? Cause designing Roof Trusses is what I do in my day job.
