My current landscaping project requires a deck to be built. The " before ' garden sloped up from the back of the house. at the top part of the garden I've removed 30m2 about 40cm's deep of soil then a step down of about 50 cms and removed about 30m2 of soil ranging from 50 cm - 10cm to take some top-soil and turf form a flat lawn. The lawn will have 4 steps up to the deck which will actually be lower than the original height of the garden. will I need planning as the deck is more than 30cm's higher than the lawn although the lawn is 50cms lower than it used to be?

Putting up decking, or other raised platforms, in your garden is permitted development, not needing an application for planning permission, providing:
The decking is no more than 30cm above the ground
together with other extensions, outbuildings etc, the decking or platforms cover no more than 50 per cent of the garden area.
Please note: the permitted development allowances described here apply to houses not flats, maisonettes or other buildings. View guidance on flats and maisonettes here.
