Perceiving an object requires that we distinguish it from its surroundings. The joke about a blank piece of paper being ‘a polar bear in a snowstorm’, applies to our perception.
Buildings and rooms need the same balance of positive and negative space. Distinguishing one object from another is a matter of prioritizing and choosing which will be the object of attention and which will be the background upon which the object is set.
Because brick ovens often become the focal point of a space, I am careful to balance its presence against the other features of the environment.
