The problem with flats is the awful leasehold system (at least in England, I don't know about the rest of the UK), and the management system which often imposes silly rules and unnecessary costs, for example it was a complete waste of money for my previous complex to hire someone to mop the communal lobby every morning, getting in the way of everyone trying to go to work/school and making it dirty again the minute after the cleaner finished. Even when 100 flat owners can agree to replace a management company, only the people with the most time and able to shout the loudest get their way and impose constraints on everyone else.
I had the impression the Tories were going to meddle with the leasehold system but I don't think anything ever came of that. Tens of thousands of flat owners are still unable to sell (some because they would end up in negative equity) because of the cladding problem too
Interestingly I've just had a project at work where the architect had changed the layout from some two storey blocks of flats to terraced housing with some maisonettes and they've kept the same number of dwellings, even though each peppers (including the maisonettes) have their own garden spaces.
Having seen the two layouts, this is because actually the flats were quite wasteful in terms of space as there was a car park with an extra access road, what the houses has a long run of parking directly off the street.
The point being is that, unless you have basement/undercroft parking and/or are higher than 2 storeys, plot density may not be that much higher.

Sky have commissioned a poll on the perception of immigration:
The survey revealed deep political distrust among the public, with 52% saying they think Labour are not telling the truth about what they think on immigration, and 49% saying the same thing about the Conservatives.

There's various points, however this was interesting (note positive means 50%+1 or more):
Respondents also thought that cutting immigration would have a negative impact on the NHS, hospitality, universities and social care, but a positive effect on housing.
All sorts of things like older men were more likely to be negative than younger women, London and Scotland were generally positive whilst other areas were negative.
However the general impression I get from it is wholly some areas there's a greater than 50% negative factor, it's not as far reaching as some would imply. Also, it's possible to think that it's a negative thing, however it doesn't define how negative that feeling is.
For example, I generally hold a negative view on cheese and onion crisps, but will still eat them occasionally, however my feelings towards prawn cocktail crisps is worse and won't eat them.
In the same way, it's entirely possible to think that whilst immigration is currently too high (or even was too high at 150,000), that there's still a need for some immigration (say 90,000 or 50,000). Especially if you understand that without it (say at net zero) actually the NHS and hospitality could struggle to recruit staff and so make it worse.
