Unity and harmony

The ultimate goal in the interior design of any space is that all components of the room to create a harmonious whole.


Equilibrium is achieved when the visual “weight” of the room is distributed through the room as evenly as possible. For example, the articles of bright colors hanging from the walls will be “heavier” and merge with the colored wall.

Focal point

Each room should have an element that attracts attention naturally when someone comes in. This can be an architectural detail, a fireplace, a work of art or a distinctive piece, or even lights.


A room with good pace first draws the eye to the focal point, and then draws the eye to the other components of the room, creating a flow of visual movement.

Scale / Proportion

The room should be decorated with furniture and details that are of the right scale to the size and shape of the room, and in proportion with each other and with people using the room.

Color and details

Color can add pizzazz and create either a dark room or a bright and airy one. Select the appropriate information and you can improve the look you’re trying to create, or it can be detrimental to it.
