ceberg homes, a trend that's taking the world by storm, involve creating luxurious underground spaces in what was once considered dead space. Celebrities like Travis Kelce and Taylor Swift's beau are jumping on this bandwagon, transforming basements into lavish areas for relaxation, entertainment, or even wellness centers. These hidden gems can include pools, gyms, wine cellars, private theaters, and more.

    Travis Kelce is reportedly building an iceberg home in Leawood, Kansas, expanding his $6 million mansion with a 396-square-foot underground section featuring space for an indoor golf simulator. The project is expected to be completed by December 2024. This trend may be gaining traction in the US, but it's been popular in London for over a decade, where thousands of basement expansions have been done.

    Iceberg homes can also generate extra income when leased out as rentals. However, there are risks involved, including complex construction projects that may not increase a home's appraised value and environmental concerns due to concrete-heavy construction contributing to carbon emissions.
