A point of focus can be as simple as a favorite piece of art at the center of the main living space. Or it can be more elaborate, such as an inglenook around a beautifully designed fireplace or a composition of windows looking into the garden beyond. Its purpose is to draw you into the space and to give the area a center.
Although it is not crucial to have a point of focus in every space in the house, the introduction of one or two in key rooms can add a lot of character. In many rooms, there is an obvious focal wall surface. Usually it's a focus for one of the following reasons: It is directly above a fireplace or built-in television; it is bathed in light from a skylight or adjacent window; it is the tallest wall in the room; or it is the termination of a strong visual axis through the house.
In houses where there is a view along an extended visual axis, the end-wall surface is given increased importance. It automatically becomes one of those places that cries out for a piece of artwork--or some other object or feature--that will provide striking visual delight.
Often the fireplace or television commands attention because of its function. Whatever the focus may be, you can enhance it with special lighting or by adding a space to exhibit a special treasure.
