Love your style and you've got some beautiful furniture there! A deep aubergine purple velvet on your wingbacks would look stunning. I'd tend to stick to purples in this area to keep it classy. Also, a dark purple would be more practical with kids than a cream. I'd keep the chairs you've got, unless they are really wobbly. Get someone to check them out and give you a quote for repairs and then you'll have a price to work against to see if you can get cheaper. OnePlan is right on the style and yet I don't think they look out of place in the room. I also like the idea of bench seats or if you wanted something really different, you could get a church pew?! I don't think the room has too much dark furniture as it is a large light area. Keep us posted with pics/samples of possible fabrics you find. Also, check out fabric outlet places.

I grew up with these panel doors and remember the glorious day they were replaced by a curtain. So if you are open to the idea, for ease of use, least effort and cost that's a simple fix that your daughter may want herself. The top cabinet doors can be considered a cornice for the drapes, and can be upholstered, maybe in the same fabric as her window curtains, and a simple drape with coordinating stripe on the bottom. Search "upholstered doors" on Houzz, and you will see ideas for nailhead trim, tufting, etc as well. You may also be able to add thin trim molding in a custom design to make them special. Good luck!

The all black kitchen looks scary as. Maybe because there's no lightness in there at all.

Here's a couple of ideas that work really well as alternatives to a walk in pantry. They integrate into your wall cabinetry, allowing you to keep central spaces open and free flowing. Using drawers to create a pantry as Esselai suggests. Check out how Harn Triomax soft close drawers are used in just this way. Availble in classic white or metallic grey. Two front to back depth options - 500mm and 5500mm. And 8 drawer width options from 450mm to 1200mm. Alternatively, there are a number of quality pull out pantry options in the German designed and made Vauth-Sagel range. Some are installed with fixed fronts to match your cabinetry, and others are installed behind hinged doors. See below (from top to bottom) the VSA model, DUSA model and HSA model. These all come in a variety of width options and specs, from chromed wire shelves to sold bases with glass panelling.
