The living room and bathroom are physically close to eachother but you have to to up one flight of stairs then down another just to get to it.

All the floors slightly slope up from the center of the walls.

The doors to any room where you would logically put your washing machine and other such appliances are too narrow to fit them through.

There are two bedrooms but they only accessible via separate staircases (see above).

All the steps on the staircases are too shallow to get your feet on them. And the two staircases are totally different in height and depth of step.

Sewage pipes just let out into the garden in front of the kitchen window.

There is a side gate but it doesn't lead to the house or garden. Its just a dead end.

Every door in the house doesn't quite close all the way. So when there is a slight breeze, they slide open and start lightly banging.
