Done me thinking so shed is out and my main layout will be put into the loft and made longer so it will fill the 6x20 space,and will look like this

As i will use both 6x4 baseboards as i did in the bedroom and the 6x3 and use what timber i bought to make up the other baseboards need to expand the layout to 20ft.And i won't be building the smaller layout now either.
