There are many info sources on Australian internet sites too. I tried to cut and paste but it won't work. I think if you want to search Google and more easily access websites based in other countries it helps to type "site country code; query" eg site au; wheelchair accessible kitchen or Australia Liveable Housing Guidelines. Youtube has videos of kitchens and also search under 'handicap kitchens' on youtube and Google images. Good luck.

@Rock Doc: Are you addressing this to me? I haven't actually bought these tiles yet - when I do, I will definitely be going for the handmade ones. They're a work of art and irreplaceable in my opinion. However, there are also screen-printed tiles available in the market in more or less the same patterns; the workmanship is of course different, but you get them cheaper, and they're also more easily available. You could give that a shot. I'd recommend Aakaar Flooring Solutions - they're here on Houzz and are able to provide both the above-mentioned types.

Suggestion: Never put the gas stove below the window and chimney against the window. It is ineffective as the air blown out is likely to come back in. At the least, it can be on the right or left side of the window with the chimney on the wall. Or the best place is on a slab on the left wall.

Please find attached pics of what we had planned. But the same looks congested and placement of the fridge is difficult. We had thought of a parallel kitchen but due to the placement of the window, we are losing space. Vastu is another concern. Kindly advise.
