Wall modules fit precisely!
We constructed this modular 12' x 16' shed off-site at our workshop in 8 modules, then transported it to the job site. Because the modules fit precisely, erecting the walls took less than half a day. Before the siding and trusses can be installed, some work still needs to be done. In the right foreground of this photo, you can see the first piece of the top plate has been installed.
