A 25 year old Harry potter stood facing the ruing of Hogwarts only he and Hagrid remained at Hogwarts after the final battle even Dumbledore left unable to bare looking at Hogwarts in its current state the only intact pieces of the castle were the dungeons the Common rooms and Dormitories, the library and The Headmasters office and Rooms.
Before leaving Dumbledore passed on the tile of headmaster to Harry as Professor Mcgonagal felt the same as him, Dumbledore left hoping to begin teaching again something he missed as Headmaster and got a taste of again while training Harry for the final battle.
Surprisingly all the people Harry was Close to survived the final battle Only Percy and Charlie Weasley did not make it from the Final battle. Ron and Hermione were married with 2 children Molly and Arthur grief stricken at the death of 2 of their children eventually decided to try for another child with they did have another boy named Christopher Percy Weasley who was now 5 Fred and George were the Same as ever are both married to twins and live in 2 houses connected to each other Mad Eye is now a Elite Auror Trainer, Tonks And Remus are married and have 2 children nearly ten years old Kingsley is the same as ever but now has Amelia Bones Job as she who everyone thought dead came out of hiding and became Britain's first ever Female Minister of magic Neville and Ginny are married Ginny a professional Quiddich player Neville a Healer famous foe healing his Parents and mixing Muggle and magical medicine Safely Luna is Married to Harry and Runs The Quibbler with her Father.
Ever since the Final battle Harry had tried to find a way to bring back Hogwarts Eventually doing so when he found portrait's of the founders (amazingly All the portraits and Artifacts had Survived Hanging in mid air where they were before Hogwarts Destruction).
He found out from the Founders Portraits that When the founders were a few years from death there Performed an ancient Ritual ending there life's early so that if Hogwarts needed them they could be called on with a simple chant in the Heads office by the current Headmaster/Headmistress. So after Getting his Headmaster robes from Madam Malkin he could Summon the founders for 2 weeks so they could rebuild Hogwarts and her wards This had taken Harry a bit longer than expected as He had to calm down after he found out that Salzaar Slytherin was Muggleborn and never became a Dark Lord and had only left Hogwarts to Take control of the Slytherin estate from his Muggle mother when she died.
In his office Harry had set out Godric Gryffindor's sword Helga Hufflepuff's Cup Salzaar Slytherin's Stave and Rowena Ravenclaw's Shield Dawned his Robes and Began the chant in Indecipherable Latin after a while The founders objects started to glow then Misty Forms of the Founders appeared before they became corpreal each Holding There own possession looking rather Grim. Ending his chant Harry Said Hello but he could sense the founders Distress at the state of there life's work
"so the said Why don't we get started straight away"
The founders all looked to Rowena who waved her had and conjured up the plans of Hogwarts and stepped forward and spread them out on the table and motioned the other founders and Harry around Rowena said that herself and the other founder would take care of the destroyed part and Harry was to take care of the bits that were damaged and all of them would work on the wards to make them stronger than before so with that Rowena and the other founders left with and aura of a unstoppable person, leaving Harry to his work which was mainly repairing doors and windows and classrooms that had survived which was not a large job as most of it was done in a wave of his hand.
Harry was just Using some charms to make his conjurations permanent when he felt the founders power wash over him and what sounded like a landslide racing outside he found that the founders had just put The Stone structure of the castle back in place leaving The people of Hogsmeade extremely confused, before Conjuring windows and charming them permanent before coming over to sea Harry and saying that they were about to stat on the inside and could he deal with the classrooms and handing him the plans for them.
Five am 5 days later found a sleep deprived Harry just finishing the final touches of the transfiguration classroom before going to bed hoping for some sleep before the founders were ready to do the wards.
9 Hours later harry was woken by some ice cold water from a exited looking Helga who shoved a plate of breakfast at his and telling him they were starting on the wards in half an hour and bouncing out the room. Groaning harry got up and dressed before heading to The ward room to meet up with the Founder's.
Walking into the room Harry say the other founders were in the same mood as Helga as they had dismantled what was left of the old wards ready to start anew, Barley having time to take in that much before Godric told Harry " we are starting with the ancient anti apparition ward then the Selective portkey ward set to you ok " at seeing Harry's nod he motion Harry and the rest of the founders to Start chanting.
Two days later saw Hogwarts back in its former glory and Harry writing letter's to the staff to resume there old posts as Hogwarts was opening in exactly1 week .

Smirking as he imagined the teachers reactions Harry Handed the Letter the Schools express Owls knowing the letters would be delivered within the hour and within two most if not all the teachers would be at the gates with there belonging ready to take up there old positions.
Just as Expected 2 hours later Hogwarts told Harry that all the Staff were at the gates waiting. Smiling he went to greet His colleagues, Getting out the Carriage at the gate he was greeted by the eager faces of the staff Harry smiled as he unlocked the gates and was greeted by all the staff who piled into the carriage and waited for Harry, as Harry entered the Carriage He was Greeted By Dumbledore telling Him "I knew you could to it Harry" and Minerva telling him " If this is some king of joke you will regret it. At this Harry just smirked and told them to wait and see as the carriage got close enough for the staff to see Hogwarts all they saw were ruins for split second before Harry Removed the illusion to let them sea the newly rebuilt Hogwarts.
