I am debating on having a shop built at my house.I have no idea where to start. The only thing I know about them is build bigger than you think you need. Should I go with stick built or one of those metal buildings you see advertised in steals and deals. I want a concrete floor,electrical,heating and air. I have a spot a 30x40x10 will fit nicely. Any ideas,guesses at price and opinions are welcome.
