I'm finding it a little hard to see the detail. Can you enlarge the top 2 plans?

Personally, it's better to have a wall between the bathroom and the toilet so no one gets walked in on. Definitely a good idea to keep the bath in case of reselling, although are you planning on going anywhere? If not, get rid of the bath and get a bigger shower I think.

Provided there is 1200mm clear between the breakfast bar and the opposite bench then by rights, you should have ample room and if that's the case, I think I would opt for the design with the kitchen on the eastern side. My reason; you get a much greater feeling of open plan by having the dining and lounge on the North/South plane. I like the large WIP in this one - on paper at least. The second plan somehow feels wrong. I personally don't like the idea of having the breakfast bar being located in the lounge. If it were me though, I would ask for a 3D CAD plan of both kitchens [to walk through on the computer] before making up my mind on which one to opt for as it gives you a much clearer vision of what the finished kitchen will be like rather than looking at a flat plan.

I can't get the picture to blow up big enough to see much , but unless you are running a backpackers , I would suggest 1 bathroom for 3 bedrooms would be all you need , in fact unless you are having a 'grannie flat' or similar built in , I would think that 2 bathrooms and a 3rd powder room with its own handbasin would be all you really need . Of course , more is more luxurious , so having a second ensuite is good , having a shower and WC in every room has advanatages , mind you so does having another with a bath and twin showers , 3 seperate WC's in case you have 100 people visit , a seperate spa room with its own shower and toilet , a sauna , an outside pool with its own male and female changing rooms with showers -- in other words , do what YOU want once you get past the basics . And I'm not a fan of two doors from 2 bedrooms into a bathroom -- especially if there is a bath or shower and a toilet -- it relies on everyone working together , but also on everyone pushing the right combo of locks so that there's no accidental walking in on someone .
