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.
Welshpool
Welshpool is a town as well as area in Wales, traditionally in the area of Montgomeryshire, however presently administered as part of the unitary authority of Powys. The town is located 4 miles (6.4 km) from the Wales-- England border as well as low-lying on the River Severn; its Welsh language name Y Trallwng indicates "the marshy or sinking land". Welshpool is the fourth largest town in Powys. In English it was initially called Pool yet its name was altered to Welshpool in 1835 to distinguish it from the English town of Poole. It has a population of 6,664 (UK Census 2011), consists of much Georgian design and is simply north of Powis Castle. The neighborhood economy is mostly based upon agriculture and also regional industry. The Smithfield Livestock Market is the largest one-day lamb market in Europe, whilst the town's industrial estates are house to many various kinds of little industry. As a result of the town's small dimension and also population the tourist attraction of high street stores is restricted, suggesting most of the homeowners are forced to shop in adjoining communities like Newtown as well as Shrewsbury.
