i suggest 1200mm is the minimum along the length of the island and 90cm at the ends (providing the island is less than 90cm deep) but it really depends on the size of the island and the rest of the room

No not at all, 2.8 divided by spaces between lights (eg 4 spaces lights are hung every 700). Mark out 700 from end of bench and place a piece of tape then measure 700 again and place another piece of tape and so on. Then place the lights over the tape so that the tape is in the middle of each light this will give you an idea if it will look cramped. Good luck!

Hi Bianca, I have just seen your post. I personally think the best answer to your question will depend on a few other considerations because it really depends on the kitchen layout as a whole. Considerations may include; how will this affect the work flow in your Kitchen and what are the alternative positions available to you? Importantly; how big is your island going to be; an Island can be a great space for food preparation, meal plating, as well as the island being a social space for family as well as when entertaining. When placing the Sink in an island you may consider a sink also needs adequate additional space each side of it for the various functions it is used for; whereby placing a sink in a small Island can sometimes take away from the other benefits it provides. There is actually no clear yes or no answer, but to consider your Kitchen layout, appliance placements and its work flow as a whole. With the other things you have already mentioned here, I hope this extra helps in your decision process.

My island is 3500mm x 950mm. With a 300mm overhang. I also do not have any stools at my island because our eight seater dining table is adjacent to island. I have my double sink with drainer, and plenty of bench space, because of bench length. So works for me. As oklouise has mentioned, measurements of your kitchen will dictate how big your island is. A 1200 deep island would require you to walk completely around it to clean, unless your 6 foot five. You have also said, in one of your initial posts, that you never eat at a dining table, so maybe you need a deeper bench. But, I would like to think that once you finally renovate your home, you will have family meals around an actual table.
