A kit house is a house that is built using pre-cut pieces that are manufactured in a factory and then shipped to the building site for assembly. Think of it like a big puzzle! The pieces for the walls, roof, and floors are all made to fit together perfectly, like putting together a big lego set.
When the kit arrives at the building site, it's up to the people who are building the house to put all of the pieces together in the right order. This usually involves following a set of instructions that come with the kit house, kind of like a recipe for building a house.
Kit houses became popular in the early 20th century because they were an affordable way for people to own their own home. By buying a kit, people could save money on the cost of materials and also have the satisfaction of building their own home.
Today, kit houses are still available and are often a popular option for people who want a unique, customizable home that they can build themselves or with the help of professionals.
