This is how I put my shed together over many months with materials bought in stages.
I first started by putting down footings for the walls and concrete base that would be done at a later date. Then I made up some wall frames and lifted into place, held square by diagonal bracing. Each section was bolted together with a double header spanning the section lengths. Then the rafters were put up, which sit on pulins. After that I put up 11mm osb3 for the roof deck. This was then covered with a couple of tarps. The outside walls were then wrapped in permavent eco to make the shell weather tight. It stayed like this for a number of months. Next came the counter battens and cladding, here in Scotland it is called sarking and is nothing more than 15mmx150mm treated pine. The tarp was removed and some more permavent fitted to the roof and a green tarp tied over that, also the outside was painted. At a later date the concrete was mixed and poured and allowed to cure. Then came the insulation followed by 9mm osb3 sheathing. After all that it was door making, painting interior and electrics. As of now it is still a work in progress.
EDIT: it is 6.5 x 4.8m and 3.8m in height £2200 for all timber another £500 for screws, metal banding, truss clips, hinges, locks , electrics and other stuff like that plus £500 to build the base, it is pretty thick at approx. 300mm plus 125mm concrete as the ground was prone to flooding. The flooding problem has since been sorted. Been at it for two years with long delay while flooding issue was sorted out by Scottish Water.
