Gorilla Base DIY 9 is a complete ground screw foundation kit designed to create a strong, raised and ventilated base for sheds and garden buildings, without the need for concrete. Installation is quick and mess-free, with no digging and no curing time, so most customers can install the base and assemble their building on the same day. Please click 'play' below, to watch the video. The kit is delivered to your door and can be installed using standard household tools. It includes pre-cut structural timber, ground screws, a reusable driving handle, structural fixings, layout guidance, and clear step-by-step instructions (print and video). The kit creates nine structural frames, each measuring approximately 1.2m x 1.2m, providing a total coverage of up to 12.96 square metres (Nominal shed size approx. 12ft × 12ft — always work from metric dimensions and the shed floor plan as shed sizes if feet vary and often include roof over hang). This makes it ideal for larger garden buildings such as workshops, log cabins and garden offices. Timber can be trimmed for bespoke sizing, and many customers use any extra space for a decked area or access platform.
