"This is the best house I've ever been in."
     -- Harry Potter

The Burrow is a wizard house, owned by the Weasley family. It's at least four stories tall, built so crazily that it must certainly be held up by magic. It's located outside of the village of Ottery St. Catchpole, but so well hidden that the postman doesn't even know where it is. It has a ghoul in the attic and gnomes in the garden.

The Kitchen:
Fairly small room, with a fireplace and a scrubbed wooden table. 

Ron's Bedroom:
Located at the top of the house, on the fifth landing of the narrow staircase, just below the attic with its ghoul, the walls and sloping ceiling of Ron's room are covered with orange Chudley Cannons posters. His Cannons bedspread is a bit threadbare; it's emblazoned with the Chudley Cannons logo: two black C's and a speeding cannonball. There's a tank of frog spawn, a pack of self-shuffling playing cards, and other wonders here. The room has a sign on the door reading "Ronald's Room."

Percy's bedroom
Located on the second floor, his room has a window that opens out onto the garden (GF5). He spends a lot of time in his room. While he was at Hogwarts he spent his time writing letters to Penelope Clearwater, his girlfriend. After he left school, he worked on reports for his job at the Ministry of Magic in his room.

Fred and George's room
The twins do magical experiments in their room. Mysterious explosions and noises emanate from it. They've invented all sorts of interesting (and somewhat dangerous) magical items. When cleaning their room, their mother discovered a stack of order forms for them to sell their fake wands and magical candy to kids at school. Molly burned the forms.

Ginny's room
On the third landing (CS3). When Hermione stays over, she sleeps in Ginny's room (GF5).

The Garden:
The garden outside the Burrow has gnarled trees lining the walls, plenty of weeds and overgrown grass, a large pond, and lots of gnomes. (CS3) When the entire family is home during summer holidays and Hermione and Harry are staying as well, there are simply too many people for the small kitchen so they eat a delicious dinner in the garden (GF5).

The shed:
Mr. Weasley has stuffed the shed with various Muggle artifacts which is likes to take apart and enchantment just for fun. He used to park a Ford Anglia there, several years ago, but the car has gone missing.
