we need a floor plan of the whole house with dimensions

i have to say i can't believe you ripped out walls before planning the new rooms!! and the only place where there's enough wall space for a reasonable kitchen is in the space shown as 2900 wide...which is too wide for comfortable kitchen but, have you already installed the new wall dividing up the old living area?? and please show the position and size (tall plus wide) of all doors and windows on my plan and what is the purpose of the small space next to the entry?

2.5m is almost ideal for a kitchen in this space but you would need to change the big window to have a counter against that end wall and...1. what is the view out that window? 2. where is the door to the theatre room...3. what is the inside measurements of the small room next to the entry??.the space could be enlarged to create a tiny study off the family room if not already being used...

how does this look?? I can't see any better space for the kitchen and thisi arrangement has generous walls space for appliances but how do you feel about changing the tall window?? one options would be to add an open counter in front of the window with a venetian blind against the glass and then the counter could be e a breakfast bar with a couple of stools? OR replace the tall window with a short window and have a panel of wall cladding to fill in the gap underneath...perhaps the sink could be placed looking out towards the front yard?

Why a chefs kitchen, and did you have any idea of what you wanted before you demolished.?

Here's a wild card for you, My son is a chef, you do know that chefs never clean up it;s done for them, you have a clean up prep area and a separate cooking zone with a free standing cooker. It would be great if you could use large pocket doors to be able to open up the media room for normal family use when not being a used for movies, By closing these doors and a door to the passage plus bedroom doors you shouldn't have any problems and would end up with a more usable open plan living space. The island would be all drawers. The cooking zone could have a window splash back between the base and upper cabinets. cheers

The fridge is in the cleanup next to the sink and dishwasher, there's a second single sink in the island. you could have another DW in the island. You could two narrow pull out pantries on either end of the cooking zone with a space between them and the cooktop.

The sink would stay where it is

We used Plywood from Mr Plywood in New Castle for our large Island and bench tops, sealed with a two pot mix, super cheap. cheers

Many thanks for your kind offer

Another idea, you could have one long island or two separate, doesn't it look great with the big doors opening up the Media room, you could do as we do use headphones you get the best sound. cheers

don't forget some floor space fior the two year ols and all their toys and you still haven't said how you use the small space next to the front entry???

the entry is good..... i mean the small small square space between the entry and the bedroom??

You circled a tall storage/pantry, the built in dining is perfect in that space.
