Wow big family. I am not sure your kitchen works functionally, The bin is seperate from the sink which is in middle of prep area unless your prep on back bench, Where is the kettle and toaster (breakfast station) and the crockery and cutlery to be kept for ease of access and access from the dishwasher for unpacking.
How far could kitchen go into family area? R u having a table in the meals area or elsewhere?

Yes Kate, big family. And YES, it's a really silly design, not well thought out at all. I envisioned & requested a bay window and ended up with a 70's looking 'diner' - reference the picture vs the 3rd picture.
I can remove it but I'm sure I can work with it, as I wish to have shaker style cabinetry on just the island and the face of the 'Bay area/diner' (if I hate it, I will rip it out). 
I have 2 dishwashers (1 drawer & 1 standard size) so the bins need to be next to the sink for practicality. I have considered 2 Islands or even an L/J shape island but I am really unsure as this would then lead me to change the existing sliding doors. 
I have also considered knocking the wall put where the pantry was and turning the laundry into a butlers pantry- Even extending the kitchen back a bit further.

The old kitchen was really silly. There wasnt enought storage and too small for my family. It wasnt nice and it had to go, along with everything else (as pictured).

One problem is leading to another, creating a 'domino effect'. 

Generally speaking, Yes, it could extend through to the family area but i am trying to see if anyone has any recommendations before i start using up that space for the kitchen.

Any advice would be greatly appreciated.

What don’t you like about the designs? What functionality are they missing for you? I’d consider turning the island by 90 degrees to look out over the dining nook and then it could be longer.

Yes big reader, that (would have) made sense but if you reference the original kitchen, you will see the waste for the sink is 1980mm away from the existing cabinetry.
Once the cabinetry was removed, the void between the cabinetry and framing was bizarre, 800mm all around!?!
There is a 3.2m gap between the wall and waste. I can only move it so much as I really am trying to avoid altering the existing slab, understandably.

Give the bay window a chance. Your actual photo is showing the raw wood framing, and normal shape windows. The inspiration picture is the same framing but now painted and with cushion and accessories. Oh, and the windows are completely different. And the dimensions of the meals area are not the same as the inspiration picture.

So...what do you not like about the design of your new kitchen. You know what is required for your busy family. You know how you prepare meals etc. we do not. The space is not a big space, and I think the set out is getting the most out of the space. EXCEPT The 2x2 metre island to me has a waste of space in the middle. Unless you are all 6ft plus tall, no one will be able to reach the middle to clean. A Long Island 1000mm wide or an L shaped island would give more useable island space.

I am interested to know where your dining seating is going. Will a big 12 seater setting be place in the existing family area.

The L shape can also be the other way.

The space between cooktop and sink being 1300mm is excellent. I have the same and it is so good for many people to be working on opposite bench space. The other walkway between fridge, freezer is a bit tight for walking past open fridge doors and bench at 898mm. But people can always go the other way, if that is an issue. Personally I do not see any issues with the kitchen layout, apart from the island as said previously. I have done a quick sketch of a L shaped island on your kitchen render. I think this would work better.

I completely agree dreamer. The island is a waste as the 2x2 is useless -as you said: who could possibly make use of the centre. It's not what is needed. The bay window (of course) is completely different to the inspiration pictures. I'm hoping it will tie in nicely with colours and finishes. If not, I will address after. Yes, there is a large extension - off the opposite end of the family, heading out into the backyard. So I can use however much space I require, without having the kitchen being one of the biggest rooms in the house though.
I agree with you.
The L shape would work much better. 
This island @ 2x2 is really bugging me and is my biggest concern. Its not practical.

If it is not practical and bugging you, then I would change. It is your kitchen....

You already spending a substantial amount of money. If moving the waste gives you a lasting more fitting solution I’d def investigate it.

I’ve gone with the l shaped island and flipped kitchen so you can have a main sink on side bench tapping into water and drain in laundry. Island sink becomes smaller Have small dishwasher in island and larger next to main sink or vice versa. Gives two washing stations. With the L shaped island you can have diff zones.

Similar to kate, but flip the island which would be 1200 deep, rough drawing

Hello there, Is the space under the stairs available or usable for pantries?

No, I have opened up the stairs and created storage and an external shelf with the space that is under the stairs. It is accessible from the hallway. But that was an idea @ Kitchen and Home Sketch Designs.

Am I right in saying it is about 4.2 x 4.2 but missing the 500mm bight out for the stairs along 1600. I would plan the fridges as the first you come to as kids will go there first for a drink and you do not need them interrupting the cook. Then have the wall ovens next: the high things look better together. The setback part where the laundry is behind would make a good pantry. With the section in front of stairs brought deep enough for fr & fz then the pantry would be a good depth for appliances and storage of food. The island facing the meals bay which IMHO will look great: you can fit lots of little bottoms around banquet seating! The long ext wall with cook top and benching for prep and tea, coffee, toast. Happy to offer to draw this for you as it may not make much sense to you but I would need the correct measurements and sizes of your appliances. Cheers Margot

Hi Margot, Your design makes perfect sense. And I love that idea but the space under the stairs has been opened for storage. As for the laundry, I am 100% on board with that and have discussed having the laundry be the pantry. Makes perfect sense. 
These plans are not official, just the RE plans. You know how they can be a little deceiving. 
The area is slightly bigger, not by much though.

MsWins, No no! I was not suggesting to use the laundry for pantry but the space set back by it without moving walls..... the Fridges backing onto the stairs (so not using any more than inside the walls as marked on your plan.) then continue the wall straight in line with the front of fr, fz and oven tower to create the pantry.... Maybe I should draw it for you!? I think you would have lots of space, benching, storage with this layout and the pantry a great place for hiding things! the sink & DW would need to be on island tho. :( Cheers Margot

Ok, so I misunderstood somewhere along the way, Margot. I previously wanted to have the laundry as a WIP. I have had 2 colleagues come to design the kitchen and I'm receiving pretty much the same thing from both. I understand the space is not large and we need to manage with what we have but I feel there is so much potential. 
Yes, I would truly appreciate if you could show me how you think it would best be done. 
Keeping in mind, the appliance. 
1 x 90cm gas gooktop
1 x 90cm oven
1 x 60cm wall over
1x 60cm wall oven/microwave
1 x 86cm dishwasher 
1 x Fisher & paykel dishwasher wrapper single
1 x integrated fridge
1 x integrated freezer
1 x integrated coffee machine bosch 8 serie

All the panels will be custom, floor to ceiling with an 18mm shadow line. 
 
I will have a mix of Oak, 'charcoalish' colour. 
The island will be fluted marble (aka; finger marble), just around the front with softened, curved corners & polyurethane.

I am really stuck on the placement. But the finishes are pretty much decided upon. 

Thank you Margot.

HHMM have a quick sketch and a new phone without the right cable to connect to laptop.... something else to fix! Email I can do with a scan.......

Can’t you take a photo, on your phone, of your sketch, then go into Houzz on your phone and post the photo?

Margit has been really fantastic. So, thank you Margot for your messages, time & efforts. 
This is a picture she has forwarded to me via phone. It's had me think thrice! I'm very indecisive...Obviously

Apologies, typo! Margot ~ kitchen and home sketch designs.

So MsWins, To assist with your decisions picture yourself in the mornings, lunch time and tea time, Run through mentally all the various times you are in the kitchen, the things you commonly make, the dinners, appliances you use, spreads you put on and the stock of food you like to keep. Most importantly can you make a chocolate cake while The Man is cooking dinner and Little Johnny is getting drink and snack for mates, The Man is pouring your wine and Missy is getting the cheese plate ready? I can see appliances lined up in pantry with food goods and implements you use above and below, spices in drawers just inside accessible to cook top and app, glasses and crockery in island ready for serving, lunch boxes lined up along island and the children washing the few things that do not go in DW but that you still use even tho they may get ruined in DW! Hope that helps a bit! Regards. Margot

Yes Kate, I've already purchased the appliances and they should be ready by late February. Not sure if I previously stated, I have never lived in this house. So I'm trying to base my 'normal kitchen routine' around this kitchen. That's why I have been so indecisive. 
We are making a sea change. Heading down to Wollongong to leave the hustle and bustle of Sydney City. 
My kids (ages 10 - 20 years) are super independent - exemption applies to my (surprise) 1 year old, They are relatively quiet children/young adults. 
All appliances except for wall ovens and cooktop (obv) are integrated, to allow for a seamless flow. I do believe I have been able to take alot away from each and every post (so thank you all) and may just have created my dream kitchen. I am very excited to share the progress pictures with all on Houzz once the renovations are complete.

Fantastic to hear, MsWins. That is great news!! And a sea change to Wooly is a wonderful part of the world! We have stayed Thourolle? Another beach!! Love to watch progress too......MK

MsWins, did you previously post re what to do about stairs, laundry etc, I can see the ensuite and WIR but can't seem to find this. thanks

It always seems when people talk about having children in the home it is assumed they are little children. Those lunch box preparation days do not last long. The days of all the adult children in the kitchen at one time seems to last longer! This is what needs, in my opinion, to be taken into account. Can more than one adult work in the kitchen at any one time. With a 1300mm walkway, this is very possible and workable. As Kate has mentioned, try not to have fridges opposite sinks, or ovens opposite dishwashers etc fridges should be easily accessible from living or dining. If this is not always possible, install a under bench beverage fridge for drinks and water on dining side of kitchen.

Example

In my rough sketch I showed the Pidgeon pair fridges next to the Banquet for easy access for the family and cook. what is the width and Depth of the fridges as suggested by the installation directions

I also don't agree that the sink be on the end of the island as you enter the kitchen, it needs to be moved across.

If the Banquet hasn't been built I would suggest that a simple table and chairs would be much better for a family of 8 with young adults struggling to get in and out from behind the table.

Yes siriuskey, I did post reagarding the WIR. You have a good memory.
This is a slow renovation. Bad time of year to be renovating but it is going well. Should be in by end of Feb, early March.

Many plans pass through Houzz some of which are very similar, but then something rings a bells from plans past. There was one that is same vintage as yours where I worked the laundry to be a joint mudroom/laundry when entering the house and accessing the Powder room.

You appear to be on the home run

I honestly thought Kate or yourself may have picked it up! And yes, we did discuss the stairs and Main bedroom. 
Yes, I see the end in sight.
