Yes, your shed does need a base. This is to give it a solid, level foundation. Open soil will not help with the longevity of the shed itself or the contents within. The best materials to use to make your shed base are concrete, natural stone or wood.
Lechlade
Lechlade, or Lechlade-on-Thames, is a community at the southern side of the Cotswolds in Gloucestershire, England, 55 miles (89 kilometres) south of Birmingham and also 68 miles (109 km) west of London. It is the highest point at which the River Thames is navigable, although there is a right of navigating that proceeds south-west into Cricklade, located in the neighbouring region of Wiltshire. The community is named after the River Leach that signs up with the Thames near The Trout Inn as well as St. John's Bridge. The low-lying land is Alluvium, Oxford Clay as well as River Gravels and also the town is surrounded by lakes created from disused gravel removal sites, forming parts of the Cotswold Theme park and also numerous have currently been designated as Sites of Special Scientific Interest and nature reserves. Human occupation dates from the neolithic, Iron Age and also Roman periods and created as a trading centre offered by river, canal, roads and train, although the town's station closed in 1962. A variety of culture as well as community tasks occur centred around the Memorial Hall which was restored after a fire in 2016. The Anglican Church of St Lawrence is a Grade I listed building dating from the 15th century. There is also a Baptist Church on Sherborne Street. The growth of the close-by RAF Fairford as well as RAF Brize Norton after The second world war contributed to the development of the town.
