You would need to take this up with the landlord. If you have already spoken with the neighbor and they have said "No" the only thing left to do is go to the owner of the building.

The red brick wall as a backdrop sounds very interesting. You can get quirky posters of various liquor brands like Jack Daniels, Chivas etc in black and white and get it framed and put them on the wall. Also industrial look is very in so the bar top can be done using a copper sheet over a plywood top instead of traditional granite or marble. Also utilise any empty beer bottles or wine bottles to make a customised chandelier. For stools you could have wrought iron stools with leather seats matching the brick wall. A small wall shelf with a display of shot glasses will make the look more interesting. Hope this is helpful, it will be great if you can share pictures of the area to give some more inputs.

I am yet to find a table to pair them with but will do so soon. red,lime green,black,white,brown,blue,yellow...my god.The colors and their vibrancy is awesome.Many more colors as listed are available.

Hello Sway Is it aqua teal or teal. Along with blue it will make the setting dark for a living. Better to combine it with white as well. The blue cushions for the sofa may have a a white lining and the Curtains may have patterns of white on blue. Two bamboo chairs may be white with saffron cushions and have a feature wall with sea teal/ blue color. Thanks Amit Cornerstone Designs. Bangalore.
