Number Twelve Grimmauld Place

Hidden between two rundown Muggle homes on Grimmauld Place in London, Number Twelve was the home of the "Noble and Most Ancient House of Black" and one time headquarters of the Order of the Phoenix. Sirius Black's father was intent on protecting the house and it's occupants, doing everything he could as a wizard to secure the house, including making the property unplottable. The house had fallen into a state of disrepair since the death of the Black matriarch in the mid-eighties, until Sirius escaped from prison and gave the house to the Order in the nineties. At one point the house was under a Fidelius Charm, with the late Albus Dumbledore as the Secret Keeper. Several weeks during the summer of 1995 were spent trying to make the house inhabitable by members of the Order, various Weasleys, Harry and Hermione. In June of 1996, when Sirius Black died, ownership of the house and its house-elf reverted for a very brief period to a non-Order member (Bellatrix Black Lestrange), and the headquarters of the Order was moved. Since then, the house (and Kreacher the house-elf, who was sent to work at Hogwarts) has belonged to Harry Potter.

Grimmauld Place is roughly a mile away from King's Cross Station.

Basement

Kitchen

• Most of the basement is a kitchen with rough-hewn walls; containing a fireplace, a large table with lots of chairs, and a dresser where utensils and plates are kept. A small pantry is connected to the kitchen. A stairwell leads up to the ground floor.

Water Tank/Kreacher's Den

• In a cupboard there is a water tank, and beneath this is the area Kreacher was using as his den.

Ground Floor

Front Entrance

• The exterior of the house is neglected and dirty. The front keyhole-less door is painted black, and there is a silver twisted serpent-shaped door knocker.

Entrance Hall

• A large room with threadbare carpet, peeling wallpaper and gas lamps contains many heirlooms from the Black family including a serpent-shaped candelabra, a troll leg umbrella stand, and several old portraits. Moth-eaten mold curtains cover a large portrait of the late Mrs. Black, which can't be removed.

Upper Floors

The exact number of floors in the house is unknown, but it's probably no more than four or five total.

First Floor Drawing Room

• This room contains a writing desk, a sofa, and pair of glass-fronted cabinets on either side of the fireplace mantel. The cabinets may still contain several dark items that were resistant to being moved. A tapestry of the Black Family tree hangs on the wall.

First Floor Bedroom

• At least one of the rooms on the first floor is a bedroom, Hermione and Ginny slept there.

Second Floor Bedroom

• At least one room on the second floor is a high-ceilinged bedroom containing a wardrobe and a portrait of Phineas Nigellus Black. Harry and Ron slept here.

Third Floor Bedroom

• At least one of the rooms on the third floor was a bedroom that Fred and George slept in (we know it is directly above the room Ron and Harry used).

Fourth Floor? Bedroom

• Labeled as the "upper" bedroom, this room once belonged to Mrs. Black. Sirius Black used to let Buckbeak stay in it.

An Upstairs Watercloset

• In an upstairs bathroom, a rather murderous ghoul was lurking.
