Is there something to go beside the cooker? This is where my eye is drawn due to the painted wall below the tiles. If that’s staying as a gap, tiling down to the floor may help? If you’re going for shelving, I think some wooden ones would look best to add a bit of warmth to the space. You could even use upcycled scaffolding boards or similar with chunky metal brackets for the style you’re after.

I would definitely fill the gap - but what strikes me is the lack of colour and warmth - industrial does not need to mean no colour - you have copper/warm metallic colour inside your lamps - perhaps choose some bold art work that incorporates these warm metallic colours and maybe even a contrast like turquoise blue - add wood, plants, even a fruit bowl will help!

The cooker looks very lonely where it is, like it has been given detention for bad behaviour :-D. As has already been suggested, could another cupboard be put next to it to fill the gap? Thereby creating an L shaped area connected to the sink line of cupboards. I would also paint the walls in a warmer shade such as stone or soft grey. Shelving will also be a good idea. There are loads of crafts people on Etsy who make lovely industrial style shelving. Certainly worth a look.

I'm a big fan of home made kitchen fittings. I like the chunky, workshop feel. Here's what we did in a corner of the kitchen. I have a close up somewhere which I'll dig out if it's your kind of thing. You might like it for the gap. Cost about £35 in materials. And very little skill!

It needs wood, lots of it. There is black and white and grey in there but little else. I wouldn't add funky colours, just wood and chunky wood brackets. Maybe some matting for the floor, sisal or seagrass to add texture.

Completely agree on filling out that corner. Add a chunky extractor hood. Paint your ceiling/walls copper. Add brick wallpaper. Change the white metro tiles to ceramic wood. Hang shelves, cutlery racks.

Hi I agree with comments of the cooker ... maybe you could add and extractor furniture on top as well, I would definitely paint the walls with a Contrast tone to lighten up the room..I think the lamps are really nice so you could add shelving with accessories and plants. Please see images to inspire you ...

I don’t know whether you have children in the house but looking again at your cooker position, I would be concerned about safety. Having a clear surface both sides of a hob is advised so that you have somewhere to place a hot pan. It’s also close to a doorway which isn’t ideal. When we put in a new kitchen in our last house 18 years ago we were told we couldn’t have a hob on the end of a run or next to a walkway & I imagine safety guidelines have progressed since then. I’m sure someone on here will know current guidelines.

Yup Tamp has highlighted a very important problem - the cooker needs to come left a bit - ideally central to what’s left of that space at floor level - with work surface either side - this will stop someones pocket /arm /jacket etc catching on a pan handle as they walk past - so is a safety issue that needs addressing as a matter of urgency.
