There is a park behind our house... Some people walk their dogs though that park.. There is a full on walk out sliding patio door from our master bedroom to a deck that takes in a great view of the park There is as you suggest a roller blind that occludes the view entirely... and until we are done the blind stays closed.. During the day the blind is open so the dogs can lay on the bed and look out the door and into the park so you need not worry... We like our privacy...
