A rug is a great option, you can play it safe or go bold and the best thing is that if at a later stage you want a change just whip it out and put another down, a pop of colour will brighten and modernize your look

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!

I'm not here to argue, but an approved plan can be resubmitted as a variation for approval. The blind acceptance of an approval limits your creativity, and the clients ability to obtain the best possible solution. This problem requires thinking outside the box which is what we have offered. The client must decide if the process and cost of approval of a variation is worthwhile. They shouldn't live there wondering if only we had done this or done that due to a blind acceptance that once approved there can be no variations. Realistically everything that has been suggested should result in the need to seek an approval especially when changes to plumbing are considered. Erase what you are not happy with and redesign that space without the shackles of poor space planning. You don't have to like my suggestion but don't limit yourself either.

The island bench is definitely a show stopper - WOW! I would love to have that kitchen. Looks perfect for a family home.
