It's no secret I love a great feature tiled splash back and open shelves in a kitchen. And how amazing does this herringbone pattern look? Using a darker grout makes the pattern appear prominent, and the copper pendants are just perfect here.
Full height cabinetry allows for easy concealment of brooms/mops/vacuum cleaner. Having the washer and dryer separated creates more benchspace in an already tight area. Perhaps framing the dryer with cabinetry would create a more streamlined look.
