When I showed you the kitchen spread, Joanna left me a comment, that the doors from the kitchen and sitting room appeared to have the same view of the stairs:
Living with it though, I think Joanna was right. I worried this meant a major redraw (as the little bear's foot has to be visible through the crack in the open sitting room door) until I realised I could hang the sitting room door the other way, pushing the bottom of the stairs further down the hall:
You can still see the little bear's foot, and now it's better, as Dad couldn't possible notice it this way round. It's created a perfect spot for the cat too. Thanks Joanna!
Please people, do feel free to leave critical feedback - sometimes, being so close to a project, I miss things, so you are my fresh pairs of eyes.
