I think the first layout is fine. You might want to consider moving the door for the storage room of the master bedroom so that it opens into the hall. That way the kids can use it for overflow storage. Also, that hallway is big enough that I think it could hold a large armour, providing more closet space. (There's no need to sleep in the same room as your clothes, so long as they're not too far off.) Also, don't forget that while the drawing shows kids in double beds, this need not be the case, so there will be more room for furniture (dressers or whatever) in their rooms. Finally, that step to bedroom 4 will not be odd at all. I've seen it in other homes. It looks clumsy in the drawing but it isn't. What you'll see when you come up the stairs is a bedroom door on a slight diagonal. It's only an odd jagged step if you walk like a robot, in straight lines along the wall, which is what your eye is doing on the drawing but you won't do in real life.

Just wanted to post the most recent plan that incorporates all of the suggestions that I have received from the very helpful people on the Internet! Changes made: - added an extra bathroom on far left of the house near kids bedrooms - changed the toilet/main bathroom to move the shower over to the toilet room so that we could have 2 separate kids showering at a time (without coming into our room - although that remains and option) - moved the door to the library so that it doesn't look into the toilets/bathroom - optimised the space in our bedroom by moving walk in closet and bathroom around. This modification even allowed us room for a tub in the bathroom a so thankful for that suggestion! Now we just have to find room in the budget lol Questions: - when you walk into a bathroom, do you prefer to walk into a shower (from the door) or into a toilet? What would you prefer visible from the door itself? Logically you are going to use a toilet 9 times out of 10 so you would think that should be there first, but there is something odd about walking past a door and just seeing a toilet there... Thoughts? - is there enough room in the 2 bathrooms we created by joining the toilet and main bathroom? Dimensions are 3m by 2m (roughly) and with a shower coming out about 1m and the vanity about 550mm, that leaves more or less 1.45m to walk around, surely sufficient? If there are any other suggestions or thoughts on what you would do if this was your home we would greatly appreciate the feedback. Thanks you all so much in advance!

Here is a layout indicating some minimum dimensions for usability. I would recommend you go larger especially if two people are often going to be using the space at one time. This also does not account for window space or furniture or storage.

A very simple layout keeping the floor space within the kitchen, the WIP takes up a lot of space with not much gain, The broom cupboard could be moved to the Laundry/entrance, narrow. If the wall has been bumped out to the eaves on the deck side giving an extra 300 depth to the kitchen you could make the island 2700 x 1200 and all drawers. The wall of narrow pantry will hold all pantry needs and more, no deep cupboards to dig into. cheers
