So for convenience in the bathroom we have already determined via "a little help from my friends" that a walk-in tub combined with a shower would reduce area in one bathroom and if there is a second bathroom it could be a so-called half bath (sink + toilet) saving room there. Moving over to kitchen and dining -- we could have counter dining (bar top) and eliminate the dining table (which is inconveniently placed anyway). The bar top would also double as kitchen prep space. If we go for a two-station cooktop we can eliminate the stove (there are a number of small appliances that are for more convenient that a full blown range with oven -- e.g. Hamilton-Beach appliances.) There are built-in options for refrigeration that can compartmentize that appliance -- we want to work to get the kitchen into at least a workable L-shape if not a more preferable Galley-type layout and to pull it away from the entry door.
In short -- these guys have got to try harder.
