If Grimmauld Place is the ancestral manor and has been around since say the Middle Ages can you imagine the Black family’s horror when all of a sudden that part of muggle London is being built all around them?

“They’re building in our front yard, and it’s going to be –long suffering pause– a townhouse.”

“Muggles. Muggles everywhere! Hide the children!”

“What if we pick up Grimmauld Place and move it somewhere else?” “This thing is so old it’s being held together by gold-plated spell-o-tape and magic, do you want it to fall apart?”
