I’d have the stove on same bench as sink and put tall cupboards on fridge wall.

I agree with Kate. You'd have so much storage that you wouldn't need upper cabinets on the window wall and could instead have a much larger window.

A 1m walkway is pretty tight. If you have a drawer/door open it will be hard for someone to walk behind you, which makes it almost impossible for 2 people to comfortably use the kitchen at the same time.

please show a plan including adjoining rooms with dimensions of existing kitchen, dining and living rooms

Not fridge is 700 not 600 so keep the 1200. Island should be 900 deep to have a breakfast bar along front side

How about moving the fridge to the diagonally oposite wall, near the sluding door, out of any walk way.

then creating a pantry and utility wall across the wall the fridge is currently on.

@oklouise Hi Louise, I've edited the post with new images, thanks for commenting!

@Kate, @jen876, thanks for commenting. If I have the stove on the same side as the sink, I'm guess that would mean I need to move the window. If I move the window, would that throw off the room's symmetry?

@Alison Noble thanks Alison, that's definitely an option! Would doing that mean I no longer have a 'kitchen work triangle' or does it not matter you think?

Just an ask, the most obvious place for the kitchen is the old family room on the right. That way, your living area is open to the broad expanse of the deck. The way it is now situated, it’s a round about way of getting outside and feels cramped. You could also then incorporate the storage under the stairs.

If you are planning to use island as table only put cabinets under 1200 on left. Then you can bring seating around 3 sides at Other end. If you want extra storage you can add cabinet on wheels to slide away

Just wanted to say a big Thank you to @oklouise and apologise for my lateness of it!

The only problem is that there is currently storage to suitcases under the stairs where the kitchen is. If we change access to be under the stairs, we'd have to crawl in to get our stuff because the house drops down from where the garage is, so we are reconsidering this.

This being the case, would you put the kitchen back on the other side?

And sorry just another question regarding oklouise's design. The kitchen wall is also the wall we share with our neighbour. Is it feasible to have a rangehood on that side? How would ducting of the exhaust work? 

Apologies again for my ignorance

as always there will be compromises with how you use existing space and alternate options for suitcases that should find a home elsewhere after you make sure that you only store what you MUST keep.. but could suitcases be stored under beds, on top of wardrobes, high shelf in garage?.. we've had range hoods that exhausted through the roof, through the wall and recirculate into the room without any external exhaust vent and there are some that can exhaust down through the floor so check with your local suppliers and/or electrician and plumber for advice about most suitable rangehood from wide range of options available

If it is important to access under stairs then move fridge to pantry. Get a recirculating range hood that vents back into room
