Nobody says that a balcony does not have the right to be decorated in some bright style, especially when it is an extension of the living space.
Here is an example that will help you decorate your balcony in the Provence style. It doesn't require as much as it seems.
If we talk about the geographical object, it is a region in the south-east of France. If we talk about the style, it is a combination of new and old, natural materials, fresh flowers and calm colors in the interior.
The main element is forged railings in black or white. A simpler option is possible - wood and simple metal.
Wood, imitation brickwork, plaster, and tiles are used to decorate walls.
It won't work without furniture. This could be a rocking chair, an ottoman, low chairs, a round table, open hanging shelves.
Irises and petunias, lavender, and other flowers that grow in the southern climate will look good. Conifers, succulents, and climbing plants will also work.
Don't forget about light curtains, candlesticks and vintage lamps or garlands.
