Built my garage with the help of my boys even did the cement work and saved about 10 grand.
Not good at building and even worse at doing cement but after 5 years it doesn't leak and still standing so I'm happy.
Ya if you can read a tape measure and know which end of the hammer to use the rest can be figured out. Spent my life working in building construction. Saw a lot of stuff but still had to ask other trades questions and read books.
