Black wrought iron from the top of the glass "fence" to the ceiling of the balcony would be pretty. The contractor will know how far apart to install the WI for safety. I wouldn't have any fancy WI design, just plain. The WI could also be installed horizontally. Extending the glass would be pretty, too! If the area was fully enclosed you could keep the french doors open more often and incorporate this balcony area into your living space year round. Also it would keep out dust and wind and rain & would be easier to keep clean, maybe there could be a vent for fresh air when the weather was nice. Could you talk to someone who has enclosed their balcony for more information? Depending on the sun exposure, you might need screening, too. The furniture & colors should harmonize with your living room. Ask your family what they might use the balcony for. If to sit and enjoy the view and plants, you will want one type of furnishing and if to eat on the balcony you'll need a table and chairs, too. This is a cute balcony arrangement, but I do not know how comfortable the little WI chairs would be: http://lh4.ggpht.com/_t8-Y4w1UKrc/Sa9w-hXyEeI/AAAAAAAAVrc/hb9dAYdw59c/s1600-h/image%5B45%5D.png

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
