I live on a narrow road of terraced houses and maisonettes. All parking is on the street. Opposite ours is a row of sheds and shed-like 'garages', which back onto the road from the bottom of the gardens of the houses on the next road. None of the structures are brick, most are wood or corrugated metal, so I assume they have not required planning permission to erect. Although most of these 'garages' are large enough to drive a car in, I have only ever seen a car leaving any of them on one occasion.
Now, here's the thing. There are a lot of maisonettes on the road, ours included, and there just isn't the space on the road to park. Most of the garages have huge signs saying 'No Parking', 'Access required 24 hours a day' etc. There are no lines or parking restrictions. Two have dropped kerbs - fair enough, we definitely can't park there. And wherever possible, we will try not to park in front of the garages. But sometimes that is the only place to park, and despite the signs, it is surely still perfectly legal to park there.
So are we BU to park there if there is nowhere else to park?!
