I agree with jbantick - it's actually fine - though if you've got concrete ceilings downlights wont work. See if you can run some LED strip lights under the overhead cabinets - they're great for task lighting and adding atmosphere of an evening - just get them to put the switch as a separate switch on the gang plate. I'd be tempted to go with white shutters or large blade blinds. I'd definitely be changing the window trims (to a warm white) and if you're determined to look at changing the walls I'd think about looking at half tint of the colour that's there now or in a slightly more malted tint. Deluxe have some great colours and if you're leaning towards lighter colours (including white) - just make sure to check the colours with paint pot testers on a large piece of cardboard and use white paper under/beside it when comparing colours, also make sure that you see the samples in all lights and at several times during the day as the colours can drastically change. Your floor tiles are lovely, I wouldn't cover them up with vinyl floorboards. The tiles are super easy to clean (if you've not got one already, invest in a steam cleaner - they'll keep your tiles looking amazing and they don't use chemicals).

where does the short hallway lead and is it possible to remove that wall? with small children i would be keep as much clear floor area as possible with easy access to storage for games and toys and there appears to be enough space for two x three seater lounges and two small armchairs (that can be easily moved into different locations and but having furniture with open legs instead of covered to the floor and small coffee tables and/or foot stools will help the space feel less crowded

Neither. You have black aluminium and white walls. I don't know what colour window coverings you are putting in but if it were me, I'd go for a WOW factor look over safe and predictable. Choose a black or charcoal plank. Look at the grey of the bedroom floor It has far more WOW going for it than the planks do and it's not very dark. Do a colour board and include the window coverings and some of the other colours you are intending to dress the rooms in. Picking a few floor boards without having an overall idea of what else is going to happen is opening yourself up for disappointment.

I’ve spent the better part of a decade scoffing at luxury vinyl planks. And I still think the name is a misnomer BUT I’ve been sold on the appearance and wearability of the current generation product. Have a look at Oak and Orange. On the web and Insta. They’ve used it in a range of family homes.
