Miniature house building DIY is the process of creating small-scale models of houses using materials such as wood, paper, plastic, or clay. It often involves constructing the frame of the house, adding details such as doors and windows, and decorating the interior and exterior to create a realistic and intricate miniature version of a full-size house. This hobby can be enjoyed by people of all ages and skill levels, and can be a fun and rewarding way to express creativity and attention to detail.
