Hi everyone, I've finally gotten around to creating a "Before and After" post which includes my kitchen and the remainder of the house. Pop on over if you'd like a look! We are very happy with the finished project. Thanks, Louise

It would be much more cost effective to work with the slate. Image sent by mazgardiner looks great. If the home was purchased for rental purposes, the plinth could be painted white, benchtop and splashback tiles painted (much cheaper than replacing) to blend in with slate colours. If you are going to live in the property, sometimes it's best to live with how it is and replace later when you have better understanding of what you want. Good luck with it all!

you said you could extend towards the west to replace the laundry but what's the distance from the side of the original dining room to the western boundary and what are your long term plans for the old dining room, kitchen and the space behind the garage? if you expect to extend, as me me already said, it's much better to plan the whole house renovation and it can also be more cost effective to add new rooms than to rearrange existing spaces even if you have to do the work in stages but, as we can't read the writing on your plans, it difficult to make specific suggestions and i don't understand where you plan to add the new kitchen ...does the house have only original rooms or is part of the house an old extension? what are all the floors and walls made out and what is the height of the back deck off the ground? please show room names and dimensions on the plans in larger print and some photos inside and out would help understand the existing spaces but my initial thought would be to have a new kitchen,pantry and laundry on the garage side and use the old dining room kitchen and laundry bathroom as a new master suite..but depends on correct dimensions.

Anyway, back to the question. I think it is a wonderful idea, and example photo looks good. I would not do a banquet seating, because this restricts you on your configuration for large table gatherings. If you have large seated gatherings you can bring your table into the lounge area. I would also consult a structural engineer, just to check that the kitchen wall can be removed. You could maybe extend a 400mm deep bench for storage the full length of room. This could also be a servery for large groups, leaving the new island free for prep. For privacy a screen parallel with the front door, would fix that issue. Have fun. You have a wonderful home.
