When we talk about massive residences, the Istana Nurul Iman Palace immediately springs to mind. Located in Brunei, this palace isn't just a home; it's the official residence of the Sultan of Brunei and the seat of the Brunei government. Size-wise, it dwarfs almost every other residential building in the world. Can you imagine having 1,788 rooms? That's not a typo – almost two thousand rooms! These include 257 bathrooms (imagine the cleaning bill!), a banquet hall fit for royalty (literally), and a mosque that can accommodate 1,500 people. Oh, and did I mention the 110-car garage? Because every Sultan needs plenty of parking space, right?
