Ancestral home of the Black family, and the location is protected by a Fidelius Charm. As the house is invisible to the neighbourhood residents, the local Muggles have long since accepted the mistake in numbering which landed number 13 next to number 11.

Edgar Bones and Phoebe Adkins, the lovebirds of this story, moved in together after graduating from their respective secondary schools, finding a little flat to share as they pursued their higher educations. Living downtown was grand, but pricey, and while they loved living on a floor of the bright blue townhouse, both knew it wouldn't be forever. After Phoebe's graduation from university - and before the birth of their first child - the couple moved from the heart of the city to the outskirts, leaving behind much of the bustle in order to afford a space with, well, space. Living in the north of the borough allows them to stay connected enough to the city and its conveniences without all of its chaos. (And they hope being more secluded will help them continue flying under the radar of those who would wish to do them ill.)

It's an old abandoned house that Voldemort found to use as the Headquarters for the Death Eaters. Located in the outskirts of London in a secluded area, it's highly protected and covered in magical to keep muggles from ever finding it, as well as to keep those who are not welcome at bay. It looks abandoned and haunted to those who can't see past the charms, but it's finely furnished and works well as a place for Death Eaters to socialize and meet.

A three storied (four, counting the attic), spacious, and well-lit Tudor-style house is what the Fudge family calls home. The wizarding home is inconspicuous enough in the well-off borough, and befitting of the family's status in society.

A large manor with far too many rooms for the two people that live there.

After Wes graduated, found this reasonable flat for him and one of his roommates from Hogwarts in the busy muggle borough off the Thames. Things didn't end up working out long-term with the roommate, and with Arnie nearing graduation, the Peasegood boys decided to make it their new home for the summer of '78. Surely Wes could find another flatmate for the school year, and if it still felt like a suitable place - well, graduation wasn't that far off for the younger Peasegood!

Remus has always been simple. and that's quite apparent in his choice of living arrangements. Frankly, he is still living above what even he can afford on his muggle-job wages. It's not very spacious or nice, but's he loves the cracks in the walls. He has all he needs, a nice small kitchen, a bedroom, a bathroom, and even a small living area to entertain guests (not that he expects to get many of those.)
