You could also consider getting a higher table to eat up some space. It depends on if you want your light fixture to be the star of your foyer or the table decor. Perhaps no table and a wall hung mirror with a complimentary frame

Can't tell the size but how about a three drawer chest or a night stand type chest? May be too low though....so maybe even a taller, narrow chest....or even a pretty book shelf or a glass curio cabinet. All could be put under the beautiful light and then put a low growing viney plant on top.. Or a chair to sit at to put your shoes on or off. You can do lots of things...just try some and see how they work for you. To me the sconce should be the star of your wall.

Do you like the light fixture? If you do....then try out some of the suggestions here on Houzz. A small table with a place for keys, etc. A chair. A small console table. If you find the fixture problematic, then change it out. Instead of the sconce, have an electrician put an outlet in the wall below it, and put a small chest with a lamp on it. Don’t let a light fixture boss you around!

I looked again and saw the outlet below the sconce. Sorry! I’d remove the sconce, put a chest there with a small lamp, and hang a long piece of art over the former location of the sconce.

Not a Pro.

I would put three narrow tall vases in different sizes under that light. No need to put anything in the vases.

Yes, it would totally make sense to remove the sconce but I’m not ready to give up on it just yet since we just bought it! I didn’t realize it would be problematic since there’s been a sconce there since we moved in, but this shape is not easy to work with. I agree a bell shape would definitely make it easier to put something underneath!

I should have mentioned that we are in the process of painting the yellow interior to gray and white, and are going for a rustic-glam look. This wall will be dark gray. We will eventually change the bannister too.

A Charles Rennie Mackitosh chair would go well with your current sconce, especially if you paint the wall gray and stain the bannister a dark color.

Chairs

I love the light and wonder if it could be turned the other way around, then a tall piece of furniture.

With the new paint scheme, you could do something like this. I’d try to find one with knobs that go with the bling in your sconce. Kind of Hollywood Regency glam. Or since the wall will be a dark grey you could do white. Put one beautiful vase or sculpture you love on top. Keep it simple

wondering if something tall like this might work.

wouldn't this silver colored dresser look glam.

I’d look for a side/accent table, something simple for interest rather than looking crammed in ... and with the glam feel you’re wanting. JMO, I wouldn’t put anything square in that spot, there are already a lot of angles. I’d do round or demilune.

Just a few examples (based on the changes you’re planning, but without knowing what the entire room or your other decor looks like).

I like the idea of something with patina, since your sconce is shiny:

A bit of rustic with glam —

Or, a pedestal style piece, with a pretty vase, plant, etc, on it.

how about a long glam mirror, something like this, but the right size,

for under the light.

I'd use a tall mirror that fills most of the space, with a low upholstered curved stool. Hard to see the light fixture on my phone, but I think it's pretty cool!
