Goodie on the lamps! Don't get me wrong, I love a mirrored table, I just don't think it is doing all it can in that spot. They are great in a bedroom and also in a dark corner in a living room. I'm sure you can find the perfect place to show it off. I don't usually like radiator covers either, but sometimes, and in the right material, they can work well. Go with a shelf mounted above it if you are unsure, but because your front door (more on that later) has those wonderful vertical lines in it, you could have a radiator cover with the same long slats. I think your door is great - it has strong but simple features, that I thought fit with your clean line aesthetic, while letting in light. I may be against the grain here, but unless your house is incredibly drafty and it is a 16th Century cottage or a French chateau, I wouldn't dream of having a curtain across a door. Call me crazy, but our last house was a wonky Victorian with a beautiful, enormous front door with stained glass in it and around it and the wind used to come in so strong around the edges that I felt like I was in the Arctic Circle, but there wasn't a chance I was going to cover up such a beautiful piece of architecture. Yeah, that is a bit crazy.... You could paint it in a cream to match the rest of the house, but make the other changes to the entrance hall first, live with it for a while (next year, as you say) and then see if you still want to paint it. I'll go and look for something for the floor now while other people tell you I'm wrong on the door curtain idea!

I have just revisited this item and a thought has struck me. If you are intending to do the whole house room by room then it occurs to me that the hall should be the last area to do - simply to save tears. While you alter all the other rooms you will be carrying all materials and tools through the hallway - and of course that will increase the wear and tear factor, along with dings and scrapes from long and large bits of materials and furniture. I don't know the layout of the house, nor how badly other rooms need sorting out but I would start with rooms you actually use rather than simply pass through. Kitchen, living room, bedroom and bathroom. In fact I would suggest sorting the living room first before you get so moved into it that vacating it to work on it would be problematic. The kitchen and bathroom don't tend to attract the amount of clutter and furniture that living rooms collect, so are easier to clear to basics to start work on. During this process your hallway may well end up being a makeshift store for materials while work is going on.

We have these lights in our hall and landing. They are simple but sparkle beautifully and are very reasonably priced considering that you need four. The photos online don't do them justice - apart from the last photo which is more reflective of how these actually look in real life. https://m.johnlewis.com/john-lewis-easy-to-fit-adele-pendant-ceiling-light-natural/p231216675

To me this hallway is screaming out for some dado rail height panelling, I would run this all through and up the stairs and, as the stained glass seems to be consistent throughout, pick a colour from this, i.e. a light green to paint the panelling. Then a nice light but bold print wallpaper above the panelling would look really nice. The staircase is a nice example but needs a bit of cosmetic work to tidy it up and a new lampshade and this hallway could look great!
