It is the year 3015. The banks collapsed nearly a hundred years ago when everyone withdrew their money to buy petrol cars, as governments put up the tax on diesel fuel by 14,000% in a knee-jerk reaction to a man-made global warming scare when VW revealed that their engines were producing compounds which could harm laboratory mice. The money was not there to withdraw.
The propaganda machine failed to stem the flood of customers, social media took over, and the result was that the bankers and their puppets, the politicians, were impaled on spikes on the railings of the Palace of Westminster.
Anyhow, that is history.
People still need places to live. Bricks have become hugely expensive. And history, repeating itself, ensured that the savings that needed to be made, were made. The high vaulted ceilings of 1815 gave way in 2015 to the commonplace seven foot ceiling of the modern house.
Today, those ceilings have become a mere six feet.
