All garden buildings must be installed on a solid level base. The wooden shed base is quick and easy to assemble and an alternative to a concrete base. Constructed from pressure treated timber supported with galvanized brackets and spikes to ensure your garden building will last for many years. The shed base can be installed on slightly uneven or soft ground using the galvanised spikes or an already solid base such as a patio or existing concrete base using the galvanised brackets. The garden building is installed directly on top of the shed base which enables you to raise your shed off the ground to protect against damp and ensuring a solid and level foundation. Product size is approximate (please check product specifications for the exact measurements). Installation Included: No, Size: 17.91" H x 53.54" W x 82.68" D
