iceberg homes 冰山宅

Iceberg homes are houses with big, hidden basements that may be significantly larger than the house that appears on the surface. These basements can be as many as four storeys deep – huge subterranean bunkers often containing luxury add-ons such as swimming pools, spas, gyms, bowling alleys and cinemas. Predictably they are favoured by wealthy celebrities.

“冰山宅”是指那些拥有大而隐蔽的地下室的住宅，这些地下室比地面上的屋子要大得多。有些地下室甚至能达到四成楼的深度——这些地堡里通常包含奢华的附属设施，比如游泳池、水疗馆、健身房、保龄球室和电影放映厅等。毫不意外地，这种“冰山宅”是富裕名流们的最爱。

Example:

He joined the growing number of wealthy Londoners who have been turning their mansions into so called "iceberg homes."

与越来越多富裕的伦敦人一样，他也将自己的住所变成了所谓的“冰山大宅”。
