The QuickJACK Adjustable Shed Base System for Soft Surfaces Kit 5 is the biggest kit for grass. Large garden buildings are its job. It covers 14x8, 14x10, 15x10, 16x8, 16x10, 20x10 and 20x12 sheds. The lawn needs no levelling or preparation first.
This kit has 15 screw piles with 12-inch bearing plates. The bearing plates give up to 150mm of adjustment. Brackets tie them to your floor frame. You also get 4 corner brackets and 8 T brackets plus 3 cross plates. Everything is 4mm zinc plated steel. Sixty screws finish the pack.
You make the wooden frame. It must match the size of your shed floor. The maker recommends 2 inch wide timber. A frame this large is heavy. Fitting calls for solid DIY skills. The supplier offers no installation service.
Raising the floor keeps timbers dry and ventilated. That slows rot. The piles also anchor the building against wind. Concrete for a 20x12 shed would be a huge job. This is quicker and gentler on the garden. A 10-year warranty backs it. Got a slab already? Pick the hard surface kit.
