In the middle years of the twentieth century, families became smaller and nobody had servants. Land became more expensive in the outer suburbs and the result was smaller houses for single small families.
These houses are more compact with lower ceilings, but the great thing is the construction was simpler with flat floors and rectangular shapes which are easier to work on.
Best of all, many of them have very deeply pitched roofs which you can usually "fill in" at least at the back without any planning problems, so you can stay nearer the country and don't need to move closer to central London to get a bigger house.
