Regarding space and parking etc, a lot depends on the price of land in the area...not surprisingly.
In expensive areas, you can find a house with lots of bedrooms on a much smaller plot and with less parking, and the roads are more windy and cramped and easier to clog up when people park their extra cars all over the place. So you could be in a 4 bed, 3 storey town house that has the plot size of a 2 bed house.
To get the house with the garage and the 3 parking spaces and decent sized garden, and a development layout which isn’t made up if lots of narrow roads and houses crammed in so they overlook each other, you’re either talking about buying in much cheaper areas where land is cheap, or one of the 5-6 bed houses which is tucked away in a prime spot in the estate.
People buying a typical 3 bed terrace or semi in the south-east, especially on larger estates are often looking at 1 parking space (sometimes not in front of house, but in a compound nearby which isnt so convenient fo taking shopping in etc) and narrow roads. They are designed by planners to discourage parking, but because many household have 2 cars, people do park all over the place and getting around on such estates can become difficult and it’s often impossible for 2 cars to drive along the road from opposite directions at the same time. In part it’s a traffic calming measure, but it is worsened by cars being parked in random places. Where car parking is in compounds, people often do t use those spaces but find closer non-official spaces nearer their houses which also create congestion issues.
Yes, it’s true that Victorian houses often have zero parking and might have smallish gardens. I think we understand that in terms of the fact they were built before people had cars so don’t expect car parking as standard. But houses built in the 21st century.....we know many households have 2 cars, so building estates which cannot accommodate all the cars without them being abandoned unofficially doesn’t make sense and isn’t comparable. There is just so much poor design in term so the development itself....all done to squeeze more in, rather than provide a good living experience.
