This is what I amtrying to do...I have a property in Turkey with a large roof terrace that I want to partly roof for some shade from the summer heat. Neighbouring buildings have theirs done with metal supports but I am planning to do my own if possible with timber supports. Pictures below should hopefully give you an idea of what I am trying to acheive. I only intend to do half the roof area.

Some issues...
The walls are a kind of honycomb brick, not solid brick like the uk, so how best to attach to these walls?
Would I be best to use metal brackets at joints for strength?
What size of wood for the supports,  4 x 4?
I would have the roof out of the same corrugated stuff as in the pictures, so I wouldn`t presume too heavy.

The blue dotted line would be the apex of the roof.
The dimensions are approximate



Pictures (of similar) of what I am trying to acheive.





It will attach on to this....

I would get a local tradesman to do it, I can't imagine it would cost a fortune and would potentially save you a load of hassle.

My enquiries are genuine and if you check back over the last year or so you will see several enquiries I have made for various `trades`for both my uk house and also the `rental` in Turkey. Although not all have the link.
Unless advised otherwise by the moderators I see no reason why I should not do this, not so different (in my opinion) to a tradesman handing out business cards.

If you check the link below you will find a list of all my enquiries covering several trades on both uk and Turkish property, you will also see that in many instances I use pictures to illustrate what the problem is or what I am trying to do, in order to make it easier for others to understand.

Why not ask the neighbours what they paid to avoid getting ripped off.

In which case I would go and see how the others have been fixed. They look to have been fixed to the coping on top of the balcony wall but that on its own wouldn't give a good fixing if the wind got under it.

Plus it would have to be more substantial if made from timber and, as CW says, with some diagonal bracing.
