I have done alot of cooking...so

The kitchen sink should be a coupla easy steps from the stove and Refer a couple of steps in another direction. One should also have a work space that is close to the stove, so U can watch that bubbling pot while you work on something else.

Kitchen 1 seems the better of the two. Stove has work space to the right and sink to the right of that...easy side steps..the Refer is several steps to the left of that...good ergonomics...

If you put the stove in the island you will have to turn your back to the stove to work on somethng else. Also the Refer is not in a straight line with the stove..more walking is required. not as good of ergonomics. Remember every step and movement has to count for something and should flow...to get maximum efficency from your space.

I really don't see the point of the island...it could be a small family dining area? As such I don't think the Island is going to serve much purpose and shoule be eliminated from the design. You will have some wasted space going out to the deck if you decide on the Island The Isaland will also make your Kitchen seem more closed in. one wants to have your space seem open and spacious especially with a low ceiling. You could put in a small family breakfast table in that space instead.

Also with the Island your going to have to walk around it to get to the Dining Room..instead of walking in a straight line...You do have a staging area for the Dining Room with the counter space along that wall..or that could also be a bar area with a small sink and the plus is the Refer is a coupla steps away for ice etc. That would be a nice feature.
BTW where is the walk in Pantry?
