Now the stairs to go up are longer then original intended and the toilet needs to move into the bathroom. The best I could come up with is this: http://imgur.com/MYIDjkR
The downside is that I loose the open loft-feeling of the original plans. Also I have to cross a room to get into the bathroom. This room would be a dressing and host a washer/dryer.
I want a bath and a walk-in shower, two sinks (that can be merged into one bigger sink) and a toilet in there.
