We've been tossing around the idea of a deck from the back door for a long time, but it's certainly not on the priority list. I like the way the stair is built into the deck design and even saves a bit of space.
The washer and dryer is a little higher on the list. If we can't move it into the bathroom closet this might be another solution.
While the weather now certainly doesn't warrant dreaming of needing a fireplace it hasn't stopped me. This one would fit nicely into our existing one.
