I'll get some pix this weekend. I needed to strengthen the top edge of the walls with the same 150 x 25 planks as most sheds are stabilised by the roof being a bracing member. They were also useful when I added the roof slides outside by just using some 63mm spire screws straight through them. I've since added some vertical timber in the corners as well so I can secure bits and pieces. Some metal corner brackets from Bunnings brace the shed corners.
Your tools section and any walls, roof bracing there will help make it solid as well.
Buy a decent power drill\screwdriver and a couple of boxes of spire screws and you can assemble anything !!!
Pix coming
