We illustrate the coordination problem in the provision of distinctive architectural design that arises from design externalities within a quantitative model. To quantify the model, we conduct a quantitative review of a growing literature concerned with the costs and benefits of distinctive design as well as a survey of architectural design preferences. We find that distinctive buildings sell at a 15% premium, on average. Positive design spillovers from distinctive nearby buildings result in a 9% premium. Distinctive buildings, however, are about 25% more expensive to build. The distribution of design ratings within buildings is well described by a Fréchet distribution with a shape parameter of about 4. Parametrising the model to match these moments, we show in counterfactual simulations that the optimal subsidy of distinctive buildings amounts to 10% of construction costs.
