Natural advantages

The surface of a pond reflects light and all the changing humours of the weather and seasons, and the placing of what is effectively a mirror surface to gain the most from this quality is something that should be given major consideration.

Studying the movement of the sun across the horizon may give you an opportunity to create a dappled effect on the celing or walls inside your house, and to bring more light into a shady area. Place mirrors in the intended pond area to help evaluate the effect of the reflected light.
