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.
Y Felinheli
Y Felinheli, previously recognized in English as Port Dinorwic, is a village, area and electoral ward beside the Menai Strait in between Bangor and Caernarfon in Gwynedd, north-west Wales. The population of the town was 2,284 at the 2011 Census. Y Felinheli has its beginnings in two districts, Tafarngrisiau near St Mary's Church as well as Aberpwll to the north-east where there was a mill on the Afon Heulyn. The mill was rebuilt closer to the sea in 1633 as well as gave its name to the negotiation. The location was mainly agricultural up until the area was transformed by slate quarrying in the 19th century. A brand-new dock was built in 1828 when lime was drawn out at Brynadda and slate and also lime were filled and also culm (coal dust or anthracite slack) was brought in to discharge the lime kilns. The proprietors of the Vaynol Estate, the Assheton Smiths, had the majority of the land in Y Felinheli and developed the Dinorwic Quarry in the late 18th century, They also constructed the harbour to export slate carried to the quay by the Dinorwic Railway, a narrow scale train that was consequently changed by the Padarn Railway. Industrial growth provided Y Felinheli (Felin-hely, 1838) the alternative name Port Dinorwig or Port Dinorwic.
