Just browse through the hardware stores and the garden departments of department stores and take a look at the department store catalogs, before you work out complicated constructions. There are simple and ingenious solutions for many fixings on the balcony, where you don't need to turn a screw in concrete or masonry. Folding tables and umbrella holders are available for both balcony grilles and closed parapets.
There is enough space for four people, when the table and chairs are unfolded. Lying flat against the wall, makes the furniture combination very slim.
With just under 100 Euro you are there, and get a complete "dining group" for your balcony, which you just set up or. need to screw on. The great thing about it: It is foldable, So it only takes up space, when you need it too. Ruck, shrug! it is unfolded and just as quickly stowed away flat on the wall. The only requirement for assembly: a wall width of 160 cm, so that 87 cm long furniture (table width 54 cm, Benches 37 cm) fit in front of it.
