How to make more space on terrace ?

Build or buy shelves or plant stands to accommodate more plants in less space. Or add hooks into the ceiling and hang as many as you can to give you more space.

A pergula type from would allow you to hang more plants aroun the edge of your trace.

thanks , do you have something new , unknown for me ?

I would get one/make one of those 8' long x 4' hanging plant holders with pockets for planting. or I would create a verticle recycled 2 litre bottle garden. there are a million videos on YouTube of variations. https://www.youtube.com/watch?v=2Emf2DxhQ4E bottles: https://www.youtube.com/watch?v=OroYt8GM7As pocket wall: bet you could make this with old felted sweaters,,, https://www.youtube.com/watch?v=DPeLV5A4W4Y
