Sylvia is building a home on an empty lot. Every other home in her neighborhood is a craftsman-style bungalow, but Sylvia really wants to build a three-story gothic Tudor. Her architect explains that building such a different house will affect its value and the value of the houses around it. What principle of value is the architect taking into consideration?

The principle of contribution refers to the idea that the value of a property is determined by the contribution of individual features or improvements. While Sylvia’s unique design may have certain appealing features, the architect is more concerned with how the overall style affects value relative to other homes in the area, rather than isolated contributions.

The principle of anticipation suggests that the value of a property is affected by the expected future benefits or income it will generate. Although this principle can play a role in property valuation, the architect's concerns are focused on immediate neighborhood conformity rather than future expectations, making this choice less relevant to the scenario.

The principle of change recognizes that property values are influenced by changes in the market and environment over time. While this principle is important, it does not specifically address the issue of conformity with neighborhood styles, which is the primary concern for the architect in this situation.
