Because it is a long alley of a room, it is very hard to photograph so I will do my best!
This area is to the right of the desk. I had fun designing this wall because it was a big challenge--the window and small area had me stumped for a while! The window seat is something I drew with my carpenter and then had him cut it and nail it and I did the rest. It has storage underneath and holds things that I don't need often but want available. The craft cabinet has lots of scrapbooking items as well as a drawer that holds this year's school work that the kids bring home that I want to keep.
Here is a view from the pantry and mudroom end. The door, which is our side entrance, is in between the craft/office space and the pantry/mudroom space. At the end of this long room is our half bathroom. You can see that the side of the pantry is where I keep my calendar system. I use Outlook and print my calendar every few weeks for my family to view. That way my husband can't say he didn't know because I can then point out that the calendar is right by the door!
This space is maxed out in storage even though it is not a big room. I hope it shows you that you can get function out of any space with the right planning!
