This is going to be something different that I have never seen or tried before.
What I want to do is make kind of a series of shadow boxes in the rear of the facades.When you look through a small reveal you will see the windows giving out to a view of the backyard.From the front the windows will look curtained ,as the Victorians hated sunlight in their homes.The interior will be a matte black paint or fabric of some kind and hard to see into,especially from across the yard,I will not light the interior of the rooms but will use porch lights only.
The view from the back, through the curtained windows on the inside, will be restricted so that it will only be the yard and airplane that is readily viewable.
I haven't seen anything like this before so a lot of this will be just "winging it" and makin things up as I go along.If it doesn't work out I will just use blinds along with the curtains. I still plan for a nosy neighbor to be sneaking a look through one of the windows.Should be fun!
