Only one solution - build more houses and build the correct houses. My first house was a two bed mid terrace house in Coventry. There are hundreds almost identical throughout the city. They were in their day the correct house for the people coming to work in the new industries growing in the city. Some were built speculatively some by building societies where groups of people paid in and drew lots for the houses as they were completed, some were built to let. The point is they were the correct house for the times. By modern standards solid walls single glazed no loft insulation and outside toilets plus built on a twelve foot pitch so less than one car parking space per house no longer the correct house. What we need (I think you will like this) is a peoples house in the same sense as the VW was a peoples car. This is my best guess at what it should be but others may know better. Two or three bed versions Terraced. Parking under the ground floor for one SMALL electric vehicle. Over pavement street parking ie inward facing for a second if needed. Modern levels of insulation both thermal and sound, battery storage probably community batteries and solar on the roofs, plus rainwater harvesting. Standard houses built on production lines delivered as modules to site. It's been done, you can half the build cost (not the land cost) but there is a lot less profit to be made.No argument about building services and property management being useful/essential services which have to be paid for.
But we have housing problems and the system is not working for a large number of people, who may never get on the housing ladder, or be able to afford rents, especially in London and other places.
The cost of housing has been leveraged higher than incomes. The main responsibility for this is government policy, or absence thereof, particularly the sale of council housing and non replacement.
Private landlords are another feature. It's too easy. High rents are subsidised by housing benefit and house prices go up to match so they profit twice. Needs constraint by taxation, rent controls, minimum standards, licensing, more rights/security to tenants and so on.
2nd homes is another. This should not be possible when there is a desperate shortage.
Housing is a basic human right but house price to earnings ratio are at record high.
How would you suggest housing problem should be addressed, short or long term?

combine that with the houses I was describing

The houses built in Coventry around 1903 like mine were not built in isolation, the sewage systems went in as did shops and schools, joined up thinking three years after the founding of the Labor party eleven before the first world war. Built with the Victorian attitude that they wee going to last, no house should be designed to last less than 100 years.
To do this we all need to pay tax and in the most efficient way possible.
