Ever seen a house so big it feels like a hotel, but only a couple people live there? One Canadian mega-mansion, once listed at $15 million, has been sitting empty for years and now costs just $5 million. People online are roasting its wild design and calling it a waste of space and energy. If you want to save money (and the planet), maybe skip the mansion dreams and check out tiny homes or solar panels instead! #RealEstate #HomeDesign #Sustainability
