Building home is building everything. It is not just about the form and shape of the building, but also for everything that fulfill the rooms. Furniture is the most useful property in the house. Most of the created furniture has the main function that impress the room. As we know that without the properties inside, we would be difficult to differentiate the room. It means that something that determines the room is the function of the properties.
The explanation would be like this. If you add living room furniture, such as table and chairs in the room, that room would be the living room in your house. But still, this room is usually placed at the front side of the house after the entrance. If you add bedroom furniture, such as bed and wardrobe, that room would be the bedroom. To differentiate the main bedroom and the children bedroom, you can give different bed. Main bedroom is usually a bedroom for couple and the children bedroom is fulfilled with kids furniture. If you add home office furniture, such as working table and chair, that room would be an office room in the house. Sometimes people add the place for collection of books.
