I always think that when my best friend's parents eventually sell their house, the estate agent is going to have an absolute field day describing/selling it. Her dad is an architect, and designed the house from scratch about 25 years ago. It's wonderful, but quite bizarre, to be honest.
It's built on a slope, with the front door at the top. Inside the house, there are no less than four levels going down, and three going up.
You go in through the front door, and there's a large open-plan kitchen/dining room, with a very spacious attic above. There's also a utility room off that, with two areas, one with the washing machine / tumble drier, and one with two huge chest freezers and a built in wine rack. Then you go down a small flight of stairs to a long landing with a toilet/cloakroom and walk-in cupboard. Another short flight of stairs leads you to a large dining room, with french doors onto a patio, and a connected study/library. A third flight of stairs then takes you down to the main living area, with a large 'formal' sitting room and a slightly smaller 'casual' sitting room. There's also another toilet, and another walk-in cupboard. There's another set of french doors leading from the 'formal' sitting room out onto another patio, which looks over a large lawn. They just got a small fountain installed back there as well.
Also from the dining room level, you can go up a longer flight of stairs to a landing with two bedrooms, a large bathroom and a walk-in airing cupboard. Up another short flight of stairs there's two more bedrooms, one of which has been turned into a study so that the mum could work from home. Up the final set of stairs, there's the master bedroom (which is massive), with its own ensuite - which has a bath and separate shower cubicle as well.
Like I said, it's completely wonderful, even if it's huge, and a complete nightmare if you're not good with stairs. I stayed there for about a week a few years ago (while my parents were on a second honeymoon), and my thighs looked wonderful in a very short space of time!
