The era previous to the HOF was full of war, atomic bombs and overall destruction. I think in a sense the thought of having a constantly clean environment was always thought of to rebuild the new world after the war, and set a new standard of good hygiene. For example, the double shell doorway that had the dust blower in between represents a purity of entering a sacred space that should always remain clean from the outside world. Another example is the inner garden can't be accessible for people, trying to keep the outside world with dirt and contamination separately from the inner sacredness of the HOF. Hygiene was just engraved into that generation of houses due to the war the previous era.
