External Stairs to Raised Garden Section

[surreyeagle]

hi all - hope you can help!

I have a house with a small back yard. The house comes with land behind this yard but is is raised by 2 metres. I want to build a staircase to the land, to make it a garden.

The yard is approximately 4.2m x 2.65m. The stairs would not touch any part of the existing building, but go along the current retaining wall, with a small platform that goes into the land.

Would I be able to do this under permitted development, as it is not affecting anyone else's property?

Please see image attached for a better idea of layout.

Just an update. My council has a 'drop in' service so I went and spoke to a planning officer who said (verbally - written advice is a paid for pre-app!) that this would come under permitted development because it is not an access to the building or attached to the house (i.e. a means of getting around the house from one floor to another).
