A houzz contributor, not too long ago, had made a wine rack out of 4'x4' wooden pallets, that are used in the US to move a load of goods with a fork-lift truck. Perhaps they have them in your country. He cut them in half so they were only two feet deep and stacked them up to high counter height. The wood would be a nice contrast with your concrete, might add a little warmth to the space. cascio.offsite@gmail.com

This Cabinet is $155 at Ikea. You could take the 4 items you had hung, and put them in a "shadow box", or individual deep frames to tie then together, to create I piece that looks more substantial on the wall, Then add a little ledge for photos, and you would even have room on the cabinet for the cool bottles that were on the floor, and that cool chest could definitely find a home as an end table, or entry table. You could also add a larger plant in a really nice pot in turquoise. The cut and paste renditions arent always completely accurate in scale.

If you are into bright vibrant colors then really go for it.. You started out not afraid of color.. so don't stop now . Make it part of the color on the walls.. so a green, orange black, pink stripe in the green room,, a black/white cobalt giant blue flowers in the blue room .. Add more coordinating colors in the rooms.. Look at all the wonderful Moroccan rooms for inspiration.. Have fun

the back wall panels look like ikea besta doors. the hanging cabinet could also be besta boxes, but with customized doors. the console in front of it, you could get a similar look by using a malm console table and cutting it to height. from there you'd want to use a couple of besta cabinets to create the closed off storage. the low bench could be made with plywood and then stained or painted to match the finish of the malm/besta combo you choose. besta cabinets :: http://www.ikea.com/us/en/catalog/categories/departments/living_room/11794/ malm console table :: http://www.ikea.com/us/en/catalog/products/80196480/
