Imagine you have a big house with a high ceiling. Now imagine cutting out a room in the middle of that tall space, so it's like a second floor without stairs. That room is called a loft.
People often use lofts for special things like sleeping or playing. If you put a bed up there, it's like you're secretly hiding away from the rest of the house. You might also put toys or games up there to play with because it feels like your own secret hideaway.
Sometimes, people make lofts into big rooms with lots of windows and light. They put in furniture that is easy to move around and make it a fun place to hang out with friends.
Overall, lofts are a fun way to make use of the tall spaces in a house and create a special place for play or relaxation.
