I know that in 1960, when the builder started our estate, the pavement was bordered on one side by the road and on the other by a thin strip of grass. Next to this was built a dwarf wall, behind which was the front garden.
Some houses have claimed the grass strip as part of their front garden and some like ours, have not.
A neighbour told me that claiming the strip of land meant waiting a certain number of years after buying the house before claiming it, but there being a time limit after which the strip belonged to the council for evermore.
Whether this is accurate or not, I don't know.
My understanding, from when I did this many years ago, is that you would need to maintain your exclusive use of the section of land, for the set number of years, without the owner raising any objection. Having met that criteria, you can then make a legal claim to own the section of land, which I did.
In my case, the section was a narrow triangle of land 50 yards, by 10, bounded by a railway fence along the 50 yards, but unfenced at the 10 yards open end and owned by the local council. I added a fence along the 10 yards, and built a summerhouse, limiting the only access to via my back garden. 15 years later, I put a legal claim in for it, which was granted, this after the council came out, and attempted to prove I had not met the conditions. This was pre-GoogleEarth.
The triangle gets very much wider, beyond my back garden, is bounded by the disused railway land on one side and houses on the other, with no other access, so the council eventually fenced it all in and designated it a nature reserve. At one time, it was rented out for cultivation, but those neighbouring the area, would help themselves to what ever was grown there
