Perhaps he barters with magical beings. He could offer his services in solving magical problems for them in exchange for rare building resources. For example, he might help a group of centaurs with a prophecy issue and in return, they give him enchanted wood or special stones. He may also get help from his friends who have access to different resources. Hermione might provide some rare books with building spells, and Ron could get some things from his family's old collection.
In the fanfiction, his self - built house may have a unique defense mechanism. Maybe it has a moat filled with a potion that makes any intruder forget their malicious intent. Also, the house could have a tower where Harry can practice advanced magic undisturbed, with a view of the magical landscape around. The interior might be decorated with items from his travels, like the Triwizard Tournament mementos.
Well, one possibility is that Harry Potter builds the school in a hidden location, away from the prying eyes of the Ministry of Magic. He might create a curriculum that focuses on both traditional magic and new, unique areas of study that he discovered during his adventures.
Obviously, Harry Potter himself would be one of the main teachers. He could teach Defense Against the Dark Arts, given his vast experience in that area. Hermione would be a great fit for teaching Transfiguration or History of Magic, as she has a deep knowledge of both.
Well, if 'his house' is in a Harry Potter fanfic, it might be a really cool place. It could be a place where a character has grown up and has all kinds of memories. It might be a small cottage in the wizarding world, with a thatched roof and a garden full of magical plants. There could be a fireplace where the family gathers to tell stories of old wizarding battles.
Maybe Harry builds the house as a sanctuary for his friends who lost their homes during the war. He'd use his knowledge of magic and the help of Hagrid, who would supply some magical building materials. The house could have rooms that change according to the mood of the occupants, just like the rooms in Hogwarts.
It means that Harry Potter's character continues to exist and develop in the world created by fanfiction writers. Fanfiction allows fans to explore different scenarios and storylines for Harry that may not be in the original books or movies.
The original story has a very linear family structure and a set timeline of events. But in this fanfiction, the very foundation of Harry's existence is altered. It might change his relationships with other characters too. For example, his relationship with his mother would be extremely different as he is now in a position where he has to be the one to start the family with her. His role in the wizarding world would also shift as he now has a very unique identity that defies the normal laws of nature. This could lead to new adventures and challenges that are completely different from what he faced in the original story.
In fanfic, Harry Potter may create his own world by exploring the boundaries of magic that were previously unknown. He might stumble upon ancient spells or magical artifacts that give him the power to shape a world. He could use his connection with his friends, like Hermione's intelligence and Ron's loyalty, to help him in this endeavor. For instance, they could research together in the restricted section of the library to find ways to create new magical laws and landscapes for his world.
In fanfiction, Harry Potter might create his own magic through intense study of ancient and forgotten magical texts. He could discover long - lost incantations and then modify them to suit his needs. Also, his unique connection to Voldemort could play a role. By understanding the dark magic within Voldemort and combining it with the positive magic he's learned, he could create a new form of magic that balances both light and dark elements.
Harry might first decide on the values of his world. Is it a world that values equality above all? Based on that, he'd then start to create institutions. He could build a magical council that enforces these values. He would also need to think about the inhabitants. Would he populate it with new species or just bring in his old friends? He could use his creativity to design unique magical creatures that are different from those in the original Potter world. And of course, he'd have to establish a system of magic that is distinct yet still related to what he already knows.
