I am preparing for my next major home improvement project. The last one (1/2 bathroom and laundry room gut and redo) took me 5 solid months. I learned my lesson and want to make this one smoother. Difference is that I am sectioning off part of my garage for my home office.
My question is what is the best resource book or website for a guide? I would rate myself at average at DIY/Construction. With that said, I don't know all of the tricks and pit falls.
Very much not an expert here, but I've been doing minor DIY projects for many years. IMHO there is no single guide (or website) that covers it all. Anything that attempts to be comprehensive will give just enough detail to get you into trouble and leave you there.
In my opinion you would be better off to look for books or sites on the specific aspects, such as framing or flooring.
