12 Grimmauld Place was the ancestral home of the Black family. It was passed down from generation to generation, until it was transferred to Sirius Black who gave everything he owned to Harry Potter. It was used as a headquarters for the Order of the Phoenix, even when the ownership was transferred to Harry. The Golden Trio stayed in it for a short amount of time during the Hunt for Horcruxes.
Under Walburga BlackEdit
Walburga Black wanted to protect the house from non-pure-bloods, as the Black family motto stated. Her portrait was hung on the wall behind a curtain, and was somehow permanently stuck there with a Permanent Sticking Charm.
Under Sirius BlackEdit
The house was not well respected when it was owned by Sirius Black, because it was a symbol of his rather dreadful childhood. The house needed much clean-up, which was mostly left to Molly Weasley. The home was in so much despair that Doxies and Boggarts found their way in.
The front door opened into a long hallway, lit by a large chandelier. Its wallpaper was getting old and peeling.. Walburga Black's portrait hung in this hallway. There was also a troll-leg umbrella stand, which Nymphadora Tonks casually tripped up over.
The kitchen can be accessed from the narrow staircase at the end of the front hall. There is a table in the center, and a small cabinet where Kreacher sleeps.
The wall of the staircase leading to the first floor was decorated with the heads of house-elves mounted on fancy pieces of wood. On the first landing, there were about three rooms: a drawing room, a bedroom (which was once shared by Hermione Granger and Ginny Weasley), and a bathroom. The drawing room had long windows facing the street in front of the house, a large fireplace, and the Black family tree on the wall.
