Maybe consider painting the walls? (sorry it painted the ceiling too!) You could add aome woven baskets beneath the console and I’d add art at the bottom of the stairs. When your baby is older you could add a rug

I think plan2 looks/works best but i'd suggest a few changes. For the tower run, having only a 20mm filler is to tight and doors open more than 90 degrees so they'll be rubbing at the freezer end, i'd suggest changing the 600 and 800 larders to a 1200 breakfast style larder, having drawers and worktop inside, shelved above and power for toaster etc, the doors can be pocket style so they open then slide down the sides out of the way when in use, make the wall nib a bit wider by about 100mm so you have 50-70mm fillers at each end, probably bring the towers forward (or make them extra deep) and this would allow for the pocket doors to slide away more. Depending on ceiling height you could have extra tall towers or top boxes on top and then infill about 50-100mm up to the ceiling. Also check the height of the appliances as in the pics it looks to high, i'd have a 450 frontal with pan drawer and internal drawer instead. On the opposite wall as long as all the 800 drawer units end past the window is good, window sill same as worktop possibly, (either end the run before or after the window) lose the 400 open unit in front of the wall nib and have a door (door could be made to look like 2 drawer fronts to match) on this as it will be just a dust trap, in the 1000 drawer units i'd suggest having internal drawers for utensils etc, the corner unit is good especially with the fly moon pull out as they're great (in my opinion) and as the corner post is made on site its gives the fitter more flexibility in positioning the units as its not a fixed corner. The sink run is fine but i wouldn't suggest opening a d/washer door to let the steam out as it can damage the surrounding doors, cabinets, decor panels and even worktops (thread on mumsnet where steam has damaged granite worktops). For the island if a 500 bin is big enough then fine but you might find a 600 pull out is better as its usually a 4 bin unit, possibly change the 1000 1+2 so its a 2 pan with internal drawer and then on the other side i'd have 2x 800 which would look more symetrical. For wall units its up to you, but if its an electric hob (especially induction) the extractor should be wider than the hob and if this area is going to be a main prep area than having wall units you can add extra lighting.

It feels a little cramped to me as your access to the bath is so restricted. I’ve just put this layout together that might be worth a try. (it would require a slightly smaller bath) if you can, get some boxes in there to represent furniture and move around it before committing to anything. Also, are you planning a freestanding bath and tap?? this might look squashed in and therefore make the room feel smaller (also really hard to keep it clean round the back) I would consider a back to wall bath with the space you have. re towel rail, bit stumped on that too, could it go behind the door??

I presume that’s not in the UK? l like that flooring. It’s neutral and modern and a lot of colours will work with it but it depends on what you like.
