Thanks so much everyone for ideas, and Im reassured that lots of elements of my plan for the place has been suggested by other people so it cant be too off the mark!
The kitchen is really growing on me, its very well designed space wise and the standard of workmanship/finish of things like the surfaces is perfect - so Im not planning on changing the basic elements, or painting the drawer fronts. The shiny floor is a bit misleading in the photos, up close it more textured and pretty and is also the heat source (underfloor) so its warm and any spills are easily wiped up/ dry quickly. The whole thing is well thought through with bins, microwave etc concealed which make me want to not clutter it up too much
Im planning on painting the walls above the units, cant quite make up my mind on colour but am putting up tester patches tonight. Am thinking a clear bright warmish turquoise-blue or a light fresh green, not mint but warmer. Was also thinking a splash back of white (or possibly turquoise) metro tile but white is probably more versatile in letting me change things later, though agree to the ceiling might work well (need to consider this!). Metro tile would echo the offset floor tile and also fit with the style of the house and tie into the fireplace in the next room
I thought wooden shelves too but when we mocked some up with some oak boards we are using for shelving in another room it looks really odd, like you are trying to put 'country style' details in a very shiny metro kitchen, so I was thinking of putting up 2-3 plain white shelves with brushed chrome brackets on the wall by the sink window for display and then softening them with color and details - eg herbs plants/hanging plants, bright accessories, and adding a couple of hanging bars in chrome underneath for utensils etc.
From the motley collection of kitchenwear we have anything with bamboo seems to look better than wood so was thinking bamboo chopping block, plant pots etc amongst the accessories.
I have bought some black light fittings, a bar with 3 pendants for over each window, and was planning to get some oversized, eccentric bulbs (like the Tala ones Kintsugi suggested!) or potentially coloured glass downlighters for that, plus some small concealed downlights under the lowest shelf
The last thing is the fridge, which you only see the edge of in the pictures - its one of those american style ones with double doors and is plumbed in - so again, not a priority to change it. But I thought of getting a vinyl fridge wrap - something brighter and eccentric to make it less of a monster and more of a quirky feature.
Are kitchen rugs a thing? I cant help but thinking they are a bit impractical - get messy, collect crumbs/spills and slither about. At the moment I was just going to leave the shiny floor the way it was, but am open to flooring suggestions if anyone can link to any.
Any criticism or suggestions of this plan are very much welcomed!
