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.
Manningtree
Manningtree is a town and also civil church in the Tendring area of Essex, England, which pushes the River Stour. It joins built-up areas of Lawford to the west and also Mistley to the eastern and also the 3 parishes with each other are sometimes referred to as "Manningtree". Manningtree is a plaintiff for the title of tiniest community in England. Manningtree has generally claimed to be the smallest community in England, and in 2007 mayor Lee Lay-Flurrie said that this had been verified to her by the Census Customer Services, with 700 people in 20 hectares (using the high tide mark). Nonetheless both this figure as well as the 2011 census population for the civil parish of 900 is a lot more than the 351 population of Fordwich in Kent. In April 2009 it was recommended that Manningtree must combine with Mistley as well as Lawford to form a single parish, shedding its separate identification as a community. As of 2018 such a merger has not occurred and the town council presently asserts to be the tiniest by area. Manningtree belongs to the selecting ward called Manningtree, Mistley, Litte Bentley and Tendring. The population of this ward at the 2011 census was 4,603.
