Do I Need Planning Permission.co.uk
Making the most of your Home

Some thoughts would be appreciated. In my area I often have a client who wants a parking space in front of their property where the far end needs to be raised due to sloping ground. The parking area would be finished in a permeable surface and it will not discharge water onto the highway. The supporting wall however would be above 300mm high. Does this fall short of the PD rights as it is considered a raised terrace above 300mm high or as the parking space is level with the ground at roadside is it considered the height should be measured at this point. The PD technical notes say that on sloping ground an extension height would be measured at the highest ground level?

For sloping sites, the height is measured from the highest natural ground level adjacent to the proposal. So if you exceed 0.3m at the highest point, then PP would assumed to be required.

Thank you Damian - so I have a parking space perpendicular to the highway and 5m long. Obviously it is at ground level where it meets the highway and therefore below 300mm. However at the far end it will be 1.5m above the sloping ground and supported by a retaining wall. Do fellow users feel this is permitted development? I can find no rulings or explanation on the web.

Is there a possibility you can upload and link to a photo, which may explain the situation better?

If you imagine the ground level at the front door of the house is 1.5m below footpath level. The parking space will be almost level. Therefore at the house end it will be 1.5m above that ground level but at the footpath it will be level.

There is a reason why I asked for a photo.

Is that because it may be considered as engineering works? The issue has arisen on three projects now all with similar circumstances....

No, just so it would help me visualise the situation.

Not sure how to upload a photo. Can I send to an email?

Use a website like this...

Once uploaded, it should provide you with a link. Copy and paste that here.

Good morning all.
Did anybody have answer on this question?

Over six months since the last post... probably not.

Do you have a similar query?

I know it's a very old thread but I had a similar question. See below image please. Just trying my luck...

How big is the area you’re wanting to create? What material are you proposing?
