Brain rebuilds his shelter to show people he can do it. It takes him a long time because he is building it bigger.
Brian has to rebuild his shelter twice in "Hatchet" because his first shelter is destroyed by a tornado that unexpectedly hits the area. The second time, he rebuilds it because his first shelter gets infested with insects, making it uninhabitable. This forces Brian to adapt and learn from his mistakes to create a more resilient shelter.
