Multiple reports describe Elon Musk’s day-to-day residence as a relatively small home in Texas despite his reported global wealth. According to the coverage, Musk lives in a prefabricated house that is described as covering about 400 square feet. The articles frame the point as a contrast between his high net worth and the size of his everyday living space, noting that the home is modest compared with typical expectations for someone described as the world’s first trillionaire. The information is presented as describing the property’s size and construction type, rather than offering details such as its exact location, ownership status, or any changes over time. Overall, the sources agree on the core claim that Musk’s home is small and prefabricated, and they present it as his current living arrangement in Texas. No competing figures or alternative residential locations are offered in the provided excerpts.
