Why did bradbury choose a fully automated house instead of a factory or office building there will be some soft rain?

Bradbury chose a fully automated house to highlight the society's dependence on technology and how it can lead to a loss of humanity and connection to nature. By focusing on a house as the setting, he underscores the impact of technology on our personal lives and relationships, rather than just in a work or production environment. The soft rain serves as a contrast to the artificial setting, emphasizing nature's resilience and persistence even in a world dominated by technology.
