You could reverse the layout of the ensuite, and have the door to it through the walk in wardrobe (so you would only have one door coming off the bedroom). If I were you, I'd consider swapping the positions of the ensuite and wardrobe, so the current ensuite door becomes the wardrobe door. That way you could move the bed to the east (right), and you would have room for a seating area in the north west corner of the room (as your bedroom looks huge!). I'd also add a window on the small bit of north facing wall in that room; you already have corner windows in the living and another bedroom, so you could match those in style. Personally I don't particularly like the current layout of the main bathroom, although I can see the reasoning behind it (i.e. vanity at entrance, toilet hidden behind wall, window above bath). I think it might work better if you put the shower in the corner where the bath currently is (i.e. beside the toilet, opening to the west), and the bath on the same wall as the vanity. You'd have to move the window, of course. Alternatively, do you actually need three toilets? You could remove the toilet in the main bathroom, and you'd have room for a freestanding bath and/or a bigger shower. You could consider stealing a bit of space from the kitchen to create some storage at the entryway. I'm not sure where your garage will be, but it's really handy to have a designated place at the point of entry for all the stuff you tend to dump when you first come into the house (schoolbags, coats, mail etc). Overall, I think the layout is pretty good, but you could potentially lower the build cost by making it all a bit smaller. It's really worthwhile taking the time to figure out just how much space you actually need, and where you need it. For example, if it were my house, I'd take about half a metre off both the east bedrooms (so the house is shorter from east to west), plus I'd make it smaller north to south by slightly reducing the size of all three bedrooms, and making the kitchen a bit smaller (so the hall cupboard lines up with the back wall of the small living room). But your priorities may be completely different from mine!

I have an area of 4500 x5000mm to work with and would like to put a large island bench in not having that space along the back wall. Would an island with seating be too big at 3000x 1300mm ?First Photo is the look I want, second is our specs at present

Why did the architect say No ? I wonder if it was load bearing walls or similar -- assuming you aren't altering the window placement , it looks like you are removing 2 internal walls and that stepped in part of the external wall ? If that is the problem , maybe talk to the architect , and an engineer ,and even the council , about compromises -- maybe they will 'let' you remove 1 or both internal walls , and maybe a rejig of the overall design will fit everything ? If the architect says No because he doesn't like the design ( you are the client after all ) and/or wants you to spend more money , change architects ?

The type that look like a block of marble ? No stools...? Maybe have the block one end and seating at other end? The end you see as you walk in...no stools there. Just a clean box I'll find a picture
