Ah, so your new bench would come from out from wall like the existing one? How about doing something like this (see pic) but using a normal mirror as the back piece. It would reflect the floors and make the island (or return bench?) appear more open then it actually is. I'm not sure if a smoke mirror has been used here or just a high gloss panel. I would actually allow for more storage anyway, even if you don't envision you'll use it at this point. As they say, "you can never have enough storage".

Good luck with your bar stool selection. I completely agree with your choice to buy from a shop rather than online. I've included a photo of 2 white stools I purchased (if they suit the look you're after). A word of warning - after seeing them in someone's kitchen photo from Houzz, I bought them online. Both stools arrived badly packaged with dents & scratches on the wooden backs & both had faulty gas cylinders so seats wouldn't go up. A refund was granted months later after PayPal investigated but I had to pay to return them (cheapest freight was twice what the stools cost). Now I will always buy from a shop!

I think the fridge is in a great spot - you need it to be near the walkway so people can grab something from the fridge, without invading your space. I totally agree with keeping the services out of the island bench. I would allow 800mm between the stove and sink as you are always jumping between the two when cooking and it will minimise the amount of water getting spilt on the floor. You should make sure the dishwasher is on the far side of the sink to avoid clashing between any one stacking/unpacking dishwasher and someone cooking. If you put the sink in the pantry with all you dishes it can be really inconvenient for a family that is trying to interact with the kids. I like a pantry for storage and running a mixmaster to muffle noise in the living space. If you can place the dishwasher on the bench behind the pantry that will help. Allow 1200 mm between the bench and the opposite bench/cupboard.

My kitchen is primarily 'burnt red' and the red bricks , which are slightly less brown than the burnt red . the ceiling is white , with stainless downlights , the rest is red , charcoal , white , the odd fleck of grey and black . The floor and blind are brown wood . I don't consider it overly decorated . It opens to the dining room , which is also a natural wooden floor , a black glass top table with black legs , black steel framed chairs with red leather seats and backs , an almost black wooden sideboard , a couple of big colourful abstract paintings , and 3 walls are wallpapered in a wheat weave pattern , the 4th is that red brick . There are 2 large wooden venetians too . The lounge is , yep , red leather lounge suite and extra chairs , there's even a red leather footstool that is heart-shaped ! The TV cabinet is custom made and is nearly 4 metres long , all wood with a dark stain . The floor is wheat coloured carpet with a large shaggy red rug , a black glass coffee table , a 65 inch TV and 7 speaker home theatre , a couple of those polished search light spot lights on wooden tripods , and several original paintings ( only 1 is an abstract , the rest are people , although a couple are Picasso-esque ! ) . Not much white , not a great fan . I'll put up some pics in a couple of years when I've tidied hahaha .
