EDIT May 30 2011:
Landscaping complete. Also redesigned the Planting Station and other underdeck area. Still need the roof and siding to complete the building.
Attempt to build integrated storage building utilizing space under the deck. Smaller than we'd like, but this is a better alternative to parking a shed in the yard. Current through the rough-in stage. Next up landscaping and door(s) design, then siding to match the house.
