Closing a balcony means two quite different jobs, and one costs several times the other. The first is a glass balcony: it keeps the light and the view and stops the wind, but it does not heat the space. The second is turning the balcony into a room, which means insulating the floor, side walls and ceiling and fitting insulated glazing.
Decide which one you want at the start. Plenty of people have a glass balcony fitted and then find they cannot sit there in winter. A glass balcony is a shell, not a room.
For tighter budgets there is tarpaulin balcony closing, made with PVC fabric and clear panels. It is the cheapest option and the shortest-lived; under the Bodrum sun the fabric fades within a few years. Sensible if you want something temporary, not if you are thinking long term.
Awnings are a separate matter. They cover the top of a balcony, terrace or entrance and leave the sides open. You choose between fixed polycarbonate and metal models and folding-arm awnings. Showing them on site works best; balcony awning models are hard to judge from photographs.
Balcony closing prices diverge sharply depending on which route you take. In Bodrum we look at the balcony first, then put two or three options side by side with their figures. The survey is free and the decision is yours.
