After seeing your before/after photos in your [kitchen thread[(https://www.houzz.com.au/discussions/kitchen-reno-ideas-suggestions-please-dsvw-vd~3651370?n=11) I thought I'd bump this thread. I have a better idea of the whole space now. Have you had any more ideas of what to do? I think by cladding the whole surround and wall above could have big impact and modernise so it ties in with your new kitchen. Also give some balance as it sits alongside the glossy black bench. If you like the warm of timber, you could clad running the wood horizontally. This final photo is cataloged as a transitional look but same idea with cladding all the way up. ETA: That artwork would look great on a dark grey backdrop.

100sq.m of anything is a whole lot! Whether it be crazy paving, tiles or marble. Make sure that whatever you are laying it on is stable and secure before laying, and allow for expansion joints. The best looking crazy paving is that laid by professional stonemasons, especially if you can source large slabs of stone. The larger the stone the better it looks in a large area as there is less grouting between pavers. If you can't afford a stonemason for 100sq.m of crazy paving then the next best option is the Decor Stone crazy pave which can be laid by a tiler. https://www.decorstone.com.au/products/crazy-paving/ Best of luck, Dr Retro of Dr Retro House Calls
