Although there are lots of designs and sizes of windows, my favorites have low sills, tall heads and deep reveals.

Low sills (meaning that the bottom of the window is nearer to the ground line) produce windows that tend to have the proportions of doors. Therefore, they provide more powerful connections between inside and outdoors. Using lower sills also can make a room feel much bigger.

Tall heads (meaning that the surface of the window is nearer to the ceiling) provide much the exact same visual impact as reduced sills. In reality, a conservatory derives much of its visual impact from the lack of any substantial wall arrangement over the windows.

Deep reveals (shown in the first photo below) enliven a window by providing not only a place to put things but by emphasizing the three-dimensional quality of the surrounding wall. The deep show gives us a sense of their weight and solidity of the wall along with the security the wall provides.

An accent wall with low sills and deep reveals can be a focal point and function of art on its own. The big windows keep the accent colour from getting out of control.

Low sills don’t need to be near the ground. Some sills supply just the right height for the furniture.
