Sketchup, BIM and return on investment

Hi paddyclown,
Opinions can change, all part of the learning curve & yes, workflow not tool !

So, what is the advice if one wanted to dip ones toe in the water so to speak as a complete novice with BIM on very small domestic projects. Is there a basic YOUTUBE video that just explains what typically one should address/include in a BIM workflow for small projects & how this would be beneficial.

Also, a lot of small domestic projects that I’m involved in here in the UK, (even new build dwellings) clients seem to just want you to act as their agent for the Architectural design process for submitting & obtaining Planning permission & the same for Building Control approval. Services after that such as running the job on site, they seem less interested & increasingly seem confident in doing this with their appointed contractors.
