Privacy Blinds That Allows Good Airflow

As we are living in an upcoming project by HDB, i saw that the spacing between opposite blocks is only 20M.

My concern is that all room windows will be facing the other block. People can see easily into the house.

DO they have such blinds available? What i am looking at is

1) Blind that allows good airflow while promoting privacy

2) Have scenery pictures instead of a bland colour so it gives an illusion of escape even in our pigeon hole.

Hope to hear some suggestions thanks!!
