I think it looks good. I would probably just echo a lot of the other comments. If you want a bigger ensuite, I think you can sacrifice some of the space from the main bedroom to make the ensuite bigger. Bedrooms 2 and 3 will probably require more storage, especially with three children. The cupboard in the entry looks a little odd. I would probably just extend it so that it was the same length as the wall. Otherwise, it appears to be pretty narrow, so I would think about how it is intended to function and whether a bench seat with some baskets below the bench and some hooks above the bench on that part of the wall would meet your requirements. I do think the main bathroom needs some work. I don't think three toilets are necessary, but you definitely need to separate the toilet for the main bathroom. I would also consider trying to turn it into a three-way bathroom, perhaps by keeping the powder room toilet in the current position, but flipping it so that you enter from the opposite side (which also means that you won't see a toilet as you're walking from the entry to the living areas). I would have an open double vanity where the shower and single vanity currently is and I would enclose either a combination bath/shower or a "wet room" (perhaps with a frosted glass door to still allow light from the window or include a sky light above the double vanity). I would consider whether the study requires built in storage, whether open shelves or hidden storage. I'm also not sure what the "d" in the laundry is, but I wonder whether a larger walk in pantry wouldn't be more useful. I personally would not like the living room to be completely sectioned off from the kitchen and dining areas by full-height walls and doors. There also appears to be a bit of dead space between the kitchen bench and the dining area. This will facilitate ease of movement, but I wonder whether you could widen the "galley" part of the kitchen by moving the bench towards the dining area. I'd also have a think about how you would furnish and use the living/sitting room. It looks like a large room and it also appears that you're losing a dedicated "play room" (although the study may serve that purpose until the children are all older). Good luck!

In my early twenties I designed kitchens for my mother and two aunts (Uncle built them and they worked), but when it came to designing my own - had to fit a constrained space and no possibility of extension - I chewed my lips for ages - like Nicole, I drew and measured ad infinitum, and used graph book walls, views etc. I did one extra thing - which I think worked - I listed all that I wanted to store, and tried to analyse how I liked working in the kitchen. Some things I had to settle for because of space (such as a smaller dishwasher) but most of it has worked. We have a corner pantry, which I (and the cat, husband a bit larger) can walk into, but have not put small appliances in there - they sit in a large drawer beneath the main working bench, which also works well. It all looks good to me Nicole and thinking carefully about needs and how things work in advance usually results in something you'll be happy with. Good luck!

Lea, I got them from the Dulux website. I screenshot certain colours, then posted them to thread. Of course, it’s always best to get sample pots and try your selections where you will be using them...need to see them in all lighting and in combination with each other. You may want to speak with a colour consultant at a good paint shop; they are very knowledgeable and helpful. Also, lots of great articles on Houzz. You can can also post a Design Dilemna if you would like the wider community to mull over your colour palette and offer advice! Cheers.

Theres a few noticeable issues with the current plan. First ones are the door to bed positioning in bedrooms, certainly bedrooms 2, 3 and 4. I actually don't know where they'd be placed to provide privacy to those rooms. Just clunky design even though the sizes are quite ok. Door and window location affects the whole room. WC location to living area isn't great design, could have easily been swapped over to Laundry side instead..... The entry area at garage level isn't ideal as the entry door opens directly to bottom of staircase, not a good circulation area at all. As noted previously with glass in living areas, just too much. Actually I even doubt it would meet any thermal standards using high performance glazing systems. The little balcony off main bedroom is unusable at 800mm so is better to be removed altogether. Theres quite a few other issues with the design even though some of the sizes of the spaces are quite acceptable. While I understand the site has constraints, all projects have constraints in one way or another. I would recommend you engage another designer and compare concept outcomes. Then choose which way from there whether to run with the new one and their design or stick with the original design and work with it. Design is cheap, way too cheap in most cases so don't be concerned at spending money on a few designs to get one that works. Its a drop in the ocean compared to building costs.
