The usual suggestion is to build cities more like Berlin (for example) which has an inner city with many 4-6 storey buildings — much denser than London's terraced houses, but without the isolation of skyscrapers.
These are all solutions that ignore the main problem. They literally cannot build enough properties (whatever they are) to fill current demand. Even if they relax the regulations that we currently have in place. Even there were enough properties built the infrastructure for utilities can't be scaled easily. There are issues building new properties right now because the electric grid cannot handle the combination of that and large data centres.
Since supply of house cannot be increased to solve this problem, you need to lessen the demand. The most obvious way to do this that I can see is to put a cap on immigration that is much lower than the number of people leaving (about 400,000 people leave the UK each year). However for various reasons this is seen as absolute verboten.
BTW, I know exactly the type of buildings you are talking about (we have them in Manchester) and they are typically look awful and usually start falling apart after shortly after construction. They are also not very nice to live in (I have lived in one for short amount of time).
Despite what you might read in the news, occupancy per household is LOWER than it has been for a long time.
Partly changing social customs - and you could, legitimately I think, argue some of this is down to immigration/multiculturalism - the old landlady/boarding house model, for example, which provided a LOT of cheap and relatively comfortable roofs over heads, was based on higher trust and cultural commonality than exists today.
But a lot of demand is driven by people living alone, either due to family breakdown, old age, or just out of personal choice.
On that basis if you wanted to increase supply, levers you could pull are an even more favourable tax treatment of rent-a-room schemes (although it's already pretty generous - people just don't want to), land value taxes to encourage under-occupiers to downsize, inheritance tax changes for the same (no more favourable "family home" treatment relative to cash or pension assets) and, more difficult this, legal and planning instruments to encourage suburban densification, get streets that are largely full of decaying HMOs knocked down and replaced by mid-rise which is fit for purpose.

It has nothing to do with what I read on the news. It is simply numbers. You can come up with all these crazy schemes to increase supply which probably won't happen, or you could reduce demand that could literally be done tomorrow if they wanted to.
