Back in 2011, a friend bought an apartment, off-plan, in a new tower block in Ilford.
His Mum, who doesn't drive, bought a car parking space in the basement of that block.
As an investment.
If memory serves, it was something like £11K
Pete doesn't have a car either.
Just sayin'...
Friend of ours was looking at a new build of "Executive" 4 bedroom homes
When it came to car parking there was a 4 foot "layback" and a tiny garage. When they queried this the sales people came up with the fact that obstructing the pavement was not a real life problem so parking in their "Drive" was fine
Secondly their tiny garage was designed for a City Car as this was what "Executives" drive these days
I used to, for my extensive sins, live in a four bedroom 'executive home' in the sort of development that had gates to keep the unwashed masses out (utter waste of time, the neighbours would buzz in anyone under the vaguest pretext). Each of the twelve houses had a single dedicated parking space (plus there were 8 'guest' spaces, not one of which was ever used by a guest). I am sure I mentioned who refereed all those parking disputes. Lordy, must I have sinned in a previous life.
People will use as much parking space as they can, even if it's not a parking space. In the end, after it became clear that reason would never prevail, we simply blocked off everywhere we didn't want people to park with large planters anchored into the ground. That didn't please the houses with several cars, of course, but then as I may have pointed out, they did buy a house that clearly had a single parking space and if they didn't like it we'd make those guest spaces just that, not additional spaces for residents. For the record, this was south London, 8 minutes walk from the nearest mainline station, three major bus routes at the end of the road, another train/tram station 10 minutes walk.
Frankly, if people don't have anywhere to park their car, they have two options, move to somewhere that has additional parking or get rid of a car. When we moved, every new build estate we looked at had terrible car parking problems from the get-go and in some cases, that was without even full occupancy.
