The island can provide storage as well as a nice work area. For more storage, a pie safe or hutch in either the kitchen or dining room could help. You can of course place cupboards along the side of the kitchen that does not have windows.

We rent a cabin on a lake every year. We are so busy doing lake things that I don't do any gourmet cooking:) We do not need the storage in the kitchen that we do at home. If you need storage for beach towels and other non-kitchen items, think about window seats with storage in another room.

You can do all under counter storage with no upper cabinets. Then you can add a wall of windows to look out at the lake. If you have room for a pantry, you can add very efficient storage space..
