my suggestion would be to keep the new kitchen in proportion to the size and scale of the whole house so i prefer option 2 with cabinets only as high as the top of the window, tall narrow fridge (less than 80cm wide) next to the back door with wall mounted mw and wall cabinets all round, no tall cabinets, more counter on the fridge wall then stove, sink and dw along the window wall to make sure that there is counter on either side of the stove and sink and locations for a toaster, kettle and other appliances..but exact location of appliances depends on budget and sizes of all the cabinets you want to use.. but, if you plan to remove gas in future, why not start with electric appliances and best insulation ready to add solar power at a future date? ...eg check out the electric air sourced hot water heaters and consider an electric flame heater for the kitchen fireplace and save the gas heater for the hew rear living area although it may be possible to have one heater with hot air connected to the other rooms with an in roof ducting system and, if you have long term plans to alter the rear lean-to research options for renovating the whole house and then plan all the work in stages...eg i would have the new laundry/bathroom next to the refurbished bedroom (master suite?) and have the future new rear living area with the north aspect

There's a move away from gas to the extent that new suburbs where I live are not even being provided with gas mains. Evap cooling when we researched some time back required some windows open and I remember people complaining about that during last summer's smoke. Regardless of which systems you choose, I could not agree more with oklouise, start with good solar passive design and insulation, that's the most efficient way of reducing the reliance on and cost of heating and cooling systems.

Hello 61karwin, I do not have a range hood just an exhaust fan. I do not do much in the way of frying, I am however rather good at 'carbon' but find with a good breeze thru from open windows that it is no problem. The fan does need cleaning every now and then but I get a tall person to assist: a young one who is happy to get onto the bench! I do not see a problem unless your home is not well vented and you like cooking hot chips! Cheers Margot
