Extending garage forward towards road

[Artsy]

Hi PH

Apologies if this has been done before.

I'm looking to potentially buy a house that has a single garage at the front and a decent amount of driveway (circa 3-4 cars of space).

I was just wondering, has anyone ever tried to extent a garage forwards i.e. towards the road in order to get extra length?

From what I can tell online this would require planning permission but it then gets a bit messy with distance from the road and distance from the neighbouring property etc.

I'd be looking at something like an additional 2m just to get some extra space.

Thanks in advance.

Sorry, I should have been more specific.

The increase in size would be for gym, not car purposes so the wooden structure etc that don't require planning wouldn't work for me.
