For chair scoot and sit space, I'd follow the guidelines for a rug - 4' all around. Then you want to be able to navigate around the table while people are seated, so add another 18" all around. Are you locating the table at the end of the galley? Maybe you could use a banquette on one side or in the corner https://www.houzz.com/photos/3rd-street-bungalow-traditional-kitchen-austin-phvw-vp~214425

we will replace chairs as well.....the space is quite a small area between kitchen and lounge....

I have your setup #1 and it works well, we do drip a bit of water on the floor between sink and dishwasher, but you learn not to!! Also it gives a full clear bench on the peninsular for eating, setting out, or working or whatever. Your kitchen is slightly narrower, from memory ours is 1.6M not 1.3 as you have yours, Our peninsular has a circular end which has actually proved very beneficial for sitting round, and seats up to 5, meaning you are not sitting in a long line, but facing each other round the end, - I love it, it is a real gathering point. The outer side of the peninsular curves in to the centre, then flows out to make the circular ending, so its not protruding into the kitchen but into the other side, sorry I don't think I can add a sketch to this.

These houses were designed to look good from the street, regardless of what the orientation was for the Sun. Everything depends on your budget and how far your prepared to go. A friend's house in Queenstown faced the street, the toilet and bathroom had the best view of the lake and the Sun. They got a house removal Coy in, jacked it up put it on the truck drove out and turned it around and reconnected all the services. It then faced the North and West great views and warmth, doubled its value in 3 days!. I replaced my storage water cylinder with a outside gas one, picked up enormous space in our laundry. Another tip is to draw up your "dream" plan, then overlay it over the existing and see what you can really do, your then not influenced by what is already there, and often get a much better insight and removed from the existing. Good luck, its very rewarding and make it fun!
