I'm looking to buy some land that once had train tracks on it.with the track gone can I put a trailer on it? - trailer porch

the land where the slope is 10-15 feet above the rest of the world and this is where I want my house. is an adaptation of caravans on them? I know that the planned construction of the front and back porch, which doubles as a garage and storeroom shed.will this work?
