Suggestions for a kitchen layout for my house?
My neighbors had a similar long, narrow kitchen to work with.

They decided to go with a long island down the middle, with the 'work triangle' on one side (fridge at the end of the island, sink and stove along the exterior wall of the house).

The advantage is that people can be cooking on one side (there's enough space for someone to pass behind someone else working, although they might need to coordinate if they're moving a hot pot or a tray out of the oven), while people who are just there to socialize can stay on the other side, out of the way.  Or, they can even help out with chopping stuff up, if you need some extra hands.

The last few feet of the center island doesn't have cabinets under it, it just has a central support, so they can get 5 stools around it (two on each side, one in the middle), where the kids can sit when doing their homework, or the family can sit there for breakfast or dinner.  (there's another table in the kitchen, but the kids (2,5,10) prefer sitting at the counter)

...

The kitchen planner they met with insisted they didn't have enough space for a central island, but she was insistent that she wanted one, and the kitchen deigner finally relented.

I'll see if I can get some pictures and measurements, so we can see how it compares to the size you're dealing with.
