So my washer and dryer are in my "not yet a kitchen" and I don't have anywhere else to put

4. In the process of doing some major remodeling I discovered:

1) Excavating for more basement space is very expensive. So I didn't do that.

2) The existing basement is small, with a low ceiling and an awkward stairway, so I decided not to put the washer and dryer down there if I couldn't improve it.

3) I was advised not to put the washer and dryer upstairs because of the expense of all the new plumbing and wiring, plus the fact that if the washer leaked it could ruin the floor plus the ceiling and wall below it (even if you put a water catcher and drain underneath the washer).

So I stacked the washer and dryer in the remodeled kitchen, as is common in Europe. It's worked out just fine and saved me a bunch of money.

You could enclose the side porch, but when I looked into doing something like that I was told the building code required installing 4' footings, which the old porch didn't have and which also would be expensive. Depending on what your layout is and how much space you have in the kitchen, you might just want to leave them there. Stacking them doesn't take up so much room and you'll already have plumbing connections you can attach them to.
