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.
Aberdovey
Aberdovey, or Aberdyfi in Welsh, is a village in Gwynedd, on the west cost of Wales. It was originally a shipbuilding village, but is now a popular seaside resort with award-winning beaches. It had a population of 1282 in 2011.
The town centre is situated on the river and seafront, but it stretches back far from the coast and up the hillside. The town is in the Snowdonia National Park, making it attractive to tourists. Many holidaymakers from the West Midlands go on holiday there, as it is less than 100 miles to the east of Aberdyfi. There are lots of activities to do along the beach, including sailing, kitesurfing and dinghy racing.
It is likely that the community has had inhabitants for a long time. There is evidence that the Romans formed a track into Aberdyfi as part of their occupation of Wales in AD 78. Pen-y-Bryn, the hill in the centre of Aberdyfi, is claimed to be the site of the fortifications founded in the 1150s. These were soon destroyed.
