Prefabricated House and Musk
Musk's connection with prefabricated houses is primarily reflected in his choice to live in and promote the Casita prefabricated, modular, and movable residence designed by Boxabl, while also advancing this technology towards Mars colonization scenarios.
Residential Choice and Product Features
After selling his mansion in California, Musk chose to live in a Boxabl Casita residence in Starbase, Texas (near the SpaceX base). This residence adopts a foldable prefabricated modular structure, with a total floor area of approximately 37 square meters and a total price of around $50,000 (increased to $69,000 after improvements). Its core materials are concrete slabs and steel, ensuring both structural stability and durability. Rapid installation and mobility are significant advantages: the house can be prefabricated in a factory, folded for transportation, unfolded on-site using a crane, and connected to utilities, with installation taking only about 1 hour; it can also be towed by Tesla vehicles (such as the Model X), making it suitable for frequent changes in residence.
Technological Foresight and Environmental Philosophy
The design of the Casita deeply integrates Musk's environmental and smart home philosophies. The roof is equipped with solar panels, with excess energy stored in the Tesla Powerwall system, forming an independent energy supply; an integrated rainwater collection and filtration system enhances water resource utilization; the Tesla Home app allows real-time monitoring of the house's status and remote control of devices, enabling full smart home management. Additionally, Boxabl has collaborated with SpaceX, planning to apply the Casita to Mars colonization scenarios, such as using its modular structure to quickly build Mars bases, further demonstrating Musk's forward-looking layout for prefabricated house technology.
Market Impact and Industry Promotion
Musk's示范效应 (demonstration effect) has significantly driven the development of the prefabricated house market. Boxabl currently has over 120,000 customers on its waiting list, with more than 5,000 having paid deposits, reflecting strong market demand for industrialized housing. The global prefabricated house market continues to grow, reaching $142.99 billion in 2025 and expected to increase to $153.79 billion in 2026. Through his personal choice, Musk has made industrialized housing a potential solution to the housing challenges faced by young people, while also providing technological reserves for long-term goals such as Mars migration, showcasing the dual value of prefabricated houses from Earth applications to interstellar expansion.
