Yep this thread will teach you how to build your own shop house in several easy steps.
This block of shop houses is down near my land and has just been started on.
Anyway first off you need some scraps of wood, these you need to whack into the ground to run your lines from so you can get all your posts in nice straight lines, with this job as it is quite a big one they got a digger in for the day to dig out for the footings.
