"very similar" isn't much to go on. If you want a studio type/efficiency kitchen this one might work. As in you don't cook much or plan an active kitchen.

posting a layout with measurements, doors, windows, open areas and surrounding rooms will bring more input on it.

According to your floor plan, the back wall gives you about 16 ft. which is quite a bit. You could close off the entrance opposite the laundry area and extend cabinets there to the pantry giving you an L-shape with a large island. This would not increase your distance to other areas that much, esp. the dining area. It seems you need to weigh you priorities and needs.

This is nearly identical to the kitchen I will have - we're building right now so I can't comment on how it works in "real life". But a friend built a house with a similar layout and she loves it. I received a lot of negative comments about the layout - it is very different from the typical G shaped kitchen, but I think it will work great for our family. I made the island 10 feet long and 5 feet deep, which to me is more space than I've ever had to work with - but I'm no gourmet cook!

I have debated several times if I should close off that entry way. It wouldn't be that much futher to go when taking in groceries and such. But it would be a higher cost when it comes to cabinets.
