Do you mean water, electricity etc? Because in 1919 those were not universal (not sure about how 'common' they were in London, but in much of Western Europe they weren't even that), and heating would have been done through coal too, I presume. No double glazing or any other insulation really, wooden stairs and wooden beams between floors, no hot water taps, ...
'Living' (as in, living in a house) back then was vastly worse than it is now. Just over the last 10 years, the required (as in, required by building codes) comfort levels of houses (in Western Europe) have gone up so much that they add at least 20% to the cost of building, not counting inflation.

Ok, that does help. Yes, I had been thinking of London as having the best available at the time, the most up-do-date. I didn't consider the impact building codes have.
