This project is based on the study of the building "Marie Short House" (Glenn Murcutt) and the creation of an extension for it. This house is in Australia in a flood area, so it is elevated form the ground. Moreover it's important to highlight the structure formed by a repetitive module. I have decided to follow the line stablished by the house by repeating this module again. My proposal is a library divided in two different spaces. First of all we can find the reading place on the south front. Then, on the north front, we can find a place to store books and to study.
