why does michael not like his new house

They move to a house that Michael describes as a shabby building with a garden that looks like "wilderness."

The outside doors to the back lane must have fallen off years ago and there were dozens of massive planks nailed across the entrance. The timbers holding teh roof were rotten and the roof was sagging in. The bits of floor you could see between the rubbish were full of cracks and holes... Everything was covered in dust and spiders' webs.
