Hi Stepan,
I have found similar things from architects too. One the other day was a pull down ladder unit into a roof space was located against an outside wall where the roof pitch was 22 degrees. Even a child could not have crawled into the roof, let alone the ladder be retracted into it.

In another incident, I was involved in the electrical inspection of a house some years ago. In the Laundry there was a washing machine on one wall and two doors on the wall opposite, one to the Kitchen and the other going ouside to the closes line. The doors were six inches apart and where was the power outlet for the washing machine? You guessed it - on the sliver of wall between the two doors!

The house did not pass the inspection!
When I saw the first plans for our own house (before I got into doing plans myself) they showed a wall floor to ceiling half way along the stairwell. How they expected us to get up the stairs I don't know. They also had a ballustrade along the side of the stairwell to stop anyone walking over the edge into the stairwell - fair enough but how could they fall over - there was a solid wall there, so why have a ballustrade?
Sometimes I don't think they live in the real world - its all on paper and no visualisation! They need Envisioneer!
