The photo below is my suggestion for colour of floor. Furniture should be darker - similar to below. For the rug - choose one colour from the artwork and find a similar coloured rug. Don't put a mantle over the fireplace - it could be a health hazard - bumps and bruises. Blinds - unless you want them to make a statement I think white - to match window frames would be fine.

Hi Julie Tiles would be more durable with dogs however floor boards will be warmer and cosier especially in the bedrooms. I have floor boards and house dogs and have no problems though the boards are lighter in colour so don't show scratches readily. Plus any scuffs add to the appeal of floor boards. You will need to check with the supplier if you decide on boards as to whether they can be direct stick or have to be floated. This will be influenced by the quality of your slab and the natural moisture content of the soil. If you have to float them it will sound a little hollow even with the acoustic underlay. I would personally go for floor boards over tiles but qualifying this by saying I always prefer them over tiles in most situations. Hope this helps

I’d go with timber or cork. Cork is great in a kitchen. Easy on your feet and joints and things are much less likely to break if you drop them. Especially as you age, tiles cause fatigue if you are standing in the kitchen for too long. Cork is now available in lots of different colours and styles including charcoals and greys that might compliment your slate. It’s not all 80s orange. Of course timber can look great too. Just make sure it’s ok for kitchen use.

In an apartment you need to check before you add floating floors. Some buildings have regulations to assist with noise control. If you keep the tiles, do they have the same under tones as the paint you’re considering using?- a clash between a cool and warm white will always look odd.
