I guess you could have the window replaced and build the wall up to the right height with a smaller window. You'd need to check planning on that though and how that affects the exterior of the house as it may mean that window then won't be in line with others in the house.

I think you can transform this kitchen on a low budget to tide you over for the next couple of years. I would do the following: Try painting a sample tile to see if it will properly accept paint. If so, I'd paint them a very pale cream to make them disappear, and remove the large section of tiling altogether near the door. Wipeable paint should be sufficient here. I wouldn't change the door handles - your ideas for bringing in a few industrial styled items will work quite well even if you keep these. Industrial style bar stools (black metal and wood) + black metal industrial style lighting will have great impact on the room and tie in with the cupboard handles and radiator you already have. Photo wall on the end wall behind the breakfast area is a nice idea - just be careful how you place the frames so they don't conflict visually with the lighting you choose when you are standing at the other end of the kitchen. You could actually do this photo wall over your nice charcoal coloured radiator instead to avoid visual clashes with the light fitting. I would go for a group of photos all in the same frame finish to keep it coherent - just modern slim black frames to link with the metal on lights and bar stools. Windows - if you are not overlooked I'd leave them without blinds. It is more in keeping with the pared back industrial style you are leaning towards. Are you happy with the colour of your walls? It might just be the photo but it looks a little on the dark side - and I'm not sure grey really sits with cream very well? You could paint the walls a lighter colour - maybe something similar or the same as the tile colour you choose which will make those tiles disappear even further. Perhaps there is a tendency for many of us to try to include grey with existing schemes because it is strongly in fashion when in fact it needs careful planning to avoid it either clashing or looking too cold. (just what I've observed from experience)! If you are planning on revamping the whole kitchen in a couple of years I think doing these small changes will satisfy you as to the existing with very little outlay. If the things you choose to buy now are going to be used in the new kitchen too you won't feel as though you've wasted too much time and money now. Hope some of these ideas might perhaps be useful- I don't profess to be a professional but I really enjoy interiors and making things work!

I agree with E D the middle pic looks really good!! if your finding it expensive to paint the outside of the house and you really really hate it why don't you buy some paint and give it a go yourself? as you can see in the attached pic the contrast of black door and white house looks good 🤩 I think the new window frame option looks good too 👍🏼 or how about getting frames like the pic attached?? it would be 'less fussy' as E D says

We have had almost all our "mahogany" UPVC windows and doors replaced with Aluclad windows in RAL 7044. This is an on going project and we still have a couple of the old windows which will eventually be replaced. I have painted these in a colour matched paint by Valspar. I washed the frames, applied two coats of primer/ undercoat and two coats of exterior wood/metal paint. I have also painted the front door. I am very pleased with the results. I just need the UPVC windows and front door to last a year or two longer before I am able replace them. Might be worth a try.
