building my shed atm (literally building – started yesterday morning with the frame) – couldnt believe what these "shed" companys were charging for shite …
16mm ship lap shed with 16mm ply floor , 8mm ply roof and a frame built out of 4 x 2. no windows , and no return screws on all external screws , assembled with screws from the inside to allow it to be taken to bits in panels and moved to a new house. – roughly half the cost of an 8mm ship lap shed that looked like it would blow over if i farted inside 😉 –
back to the op – my worktop is made from the offcuts of the third sheet of 16mm ply from the floor , plenty strong – my old garage had one made of 12mm ply – held the vice well and took plenty weight !
