if you want to be able to open the doors, load the boot and walk around i think you need at least 9m x 7m but if you to also want useable work benches and storage spaces (eg for the lawn mower etc) add at least 1 m to width and length

Thank you Geluka and Margot, the breakfast bar won't be 2 level, the app we used to draw up this design doesn't allow a single piece of bench (to wrap around the support column) hence the split level look. We will have a glass door for our mud room/laundry entrance. Probably won't have a pergola as the courtyard will be quite small and narrow post extension. I am considering moving the oven tower to the end of the bench housing the stove top. Assuming a 900mm stove, 600mm oven tower that will leave 600mm clearance on either side of the stove top. Many thanks, Ee ;)

Hi Craig, there are dimension rules regarding the minimum distance between a power outlet and sink bowl and there are dimension rules regarding the minimum distance between a gas cooktop's trivet and any combustible vertical surface, however I am not aware of any dimension rules regarding the distance between a sink and Gas Cooktop. There are also no rules regarding placement of a sink and gas cooktop on an island however when doing so, always consider how you are going to use these and how much bench space you will need around each of these for you to work with these two elements efficiently. Hope this helps, Malcolm, Compass Kitchens

By your pictures you have chosen lounge settings. Is this your preference for this area, or would you be using space for actual dining and entertaining. I find that low lounges like the ones shown are not ideal for eating meals. You end up with a plate on your lap.
