We need a level base for a 6x4 shed. There is an area of existing paving slabs that look in sufficiently good condition to use as a base and could hopefully be levelled and reused. We’re open to having a new concrete base installed, but if possible it would be good to make use of the paving slabs as a small level patio base for the shed. I’ve taken a picture of the existing paved area which is approximately 6’ x 4’. The slabs lift out easily, so I’ve taken an additional photo showing where I’ve lifted out one of the slabs.
