from basic concept of architecture i use grundriss wohnung A8 as reference and made skylight in balcony ceiling (the material is lightweight steel with tempered glass and also spreading plants above them to make shady mood. i made three main furniture, they're all use effective space and they're there when you need them, thus they're hid in the wall...
the mechanized system is quite classic. they're just use hinge and slider system like ordinary cupboard or windows, but they're different in their distinctive usability. they're effective to do any balcony common activities, such as socializing, working, napping, and just to relax and watch the clouds.
material of the furniture is basically made of hard board wood with steel reinforcement, and done with glossy finish. the center furniture is finished by oak panel to add warm situation. the center furniture has two plantation box and a fruit box (see the schematics). the other (right) has function as working environment when you bored to do your work inside. and the last (left) has function as 'your stuff' compartments such as photo, books, or art sculpture, it gives accentuation to your balcony as decorative.
i hope my idea useful to be shared in this forum.. thank you :)
