Yes this is a parking thread, I know how you love these. Long time member here, but haven't posted a lot in the last 8? years. Anyway, I have included a drawing as I know I'd be given short shrift if I didn't.
Background: NDN have 4 cars, one is kept in their internal garage, two on their double driveway and the fourth usually parked up on the pavement in front of our houses (boundary line area on diagram). We have 2 cars and we park them on our double driveway behind our house/garden, so no issues around who parks where, all very clear.
I overheard NDN talking to another neighbour about paving/tarmacing over the grassed part of their front garden (question marked part on diagram) to park the fourth car on, and accessing it via the existing dropped kerb in front of their double driveway.
At present, across the front of both houses are bushes and grass, NDN very kindly cuts all of it, not just his patch. There is no visible division, but obviously it is formalised in the deeds.
My question is: if they do go ahead and tarmac/pave their land, would they need planning permission to do so, to make sure it's properly installed with drainage etc, and how might this affect us if they don't? I assume that if they don't apply for an extention to their dropped kerb, they're not going to apply for planning either.
I'm not worried about their car being parked there, I just don't want them to crack on and find out later that it hasn't; been done properly and we suffer issues with poor drainage or ground movement.
