Do you mean in the kitchen specifically or in the whole house? In the kitchen have a cupboard or two with safe things - plastic food boxes, utensils towels, aprons, plastic bowls, down low. Put catches on anywhere that has dangerous or breakable stuff. Teach them (show and repeat repeat repeat!) that some cupboards are allowed and some off limits. (Level of success in this may depend on the kid. My eldest has always listened, my youngest doesn't) Elsewhere in the house, same principle. Put the stuff that is safe for them in the lower cabinets or in storage boxes - e.g. in my hall I store shoes, hats, gloves etc in soft ikea boxes or tub trugs under a table or bench. If they pull it all out, well, it is fun for them, doesn't take me an age to put back, and they feel they have had some lee-way. However, I don't do this in every room, as I personally don't agree with putting everything that is not theirs, out of reach or above their eye level. If you don't do this, they will hopefully learn that not everything is there for them to play with and you have items that are yours. For example, I have my glasses and phone on my bedside table in the morning - if any small child reaches for them they are told "ahuh! MUMMY's...!!!" Usually stops them in their tracks at least for a second! Again, success depends on the child but if they are told often enough they will have learnt what is off limits by the time they are, maybe 4? As for keeping the child corner tidy - use boxes, bins, shelves and put them behind the sofa when not in use./ Re paint scuffs - I dont' allow crayons and pencils anywhere but the kitchen, no hands on the walls, or things with wheels to be scuffed against the wall, BUT I accept it will happen and I'll repaint in a year or two when they are more in control of their bodies!

I had a bi-fold made, less than 500$ with install. It replaces a lowes door that was not hollow core, but crappy enough to fall apart at the joints. It was the best money I have spent on a door, because it solved a huge privacy problem, and is solid as a rock. Each side is hinged on the sides, and the top rail is hidden with a piece of wood set outside it, in the same wood as the doors (cypress).

If it all fits in then why not. I don't think the desk will go with the bed or maybe it would work it the desk was painted. Do you need the desk or could you use a smaller console table for working/doing things from ? Not a fan of sliding doors would rather swop the door so it opens the other way if space is an issue. What is going on the shelves are they needed ?

What direction is it facing? that will have a huge bearing on the layout. I also would question the large Living area in addition to the family room. 1700 is perfectly adequate for a bathroom but another 100mm in width would be better.
