Lots of thoughts on a mudroom/laundry room/office. This is what I envision if we want to go basic and budget--some hooks at kid and adult heights, a bench and some baskets. Nothing fancy, doesn't take up much space.
This one would fall more in the "dream" category--I don't think we want to put in quite so much cabinetry--but we like the look. Also I liked how this one flows into the kitchen, if we needed to go that route.
This one I like because of the way they've put a countertop over the washer and dryer--I envision doing something similar with butcher block, if that's what we use in the kitchen, to provide a nice clothes-folding/work space.
This one I mostly like for the black and white floor and for the way this narrow space incorporates everything we need--laundry, office, mudroom for dropping off stuff on the way in.
If the office has to be incorporated into the mudroom, I like the idea of continuing a butcher block countertop to create a desk space.
