Easy, Mihuleko, easy! Normally only one question is required. We could use some more info, though:

Is this privacy from simple passers by staring in?
Or is it a multi-story building behind you with apartment dwellers or office workers taking a look?
Also, do you need it right away, or can you wait a year or two?
Some indication of what climate of South Africa you live in could help, too.

All of this can help us give a more intelligent answer to your question. You can answer in the space given for comments, or you could edit your question to give specifics.

Also, welcome to GoY!

Well, Tugbrethil, I commend you for your fortitude, patience and tact - many words in certain orders came to my mind in response to this cryptic 'question', but I shall restrain myself...;-))
