Do you have something that you don't want other to see or endure? Do you want extra privacy? This section should guide you in how to approach the problem.
The starting point may seem obvious but you need to think clearly what it is you are trying to obscure and from what observation points. What you are trying to obscure may be small like a garden shed or it could be a large area such as a swimming pool. Where will 'it' be visible from, a neighbours kitchen window or from the bus that goes by? Is what you're trying to hide on top of a hill or in a valley? Is it being viewed from below, or above?
If possible, sketch a diagram to show the relative size of the object to be obscured, where it can be seen from and the distance between them.
