Key assumptions in development viability testing
The council uses five key assumptions when determining development viability: benchmark land value, Gross Development Value, developer return, construction/development costs, and policy compliance costs.
In summary, the key assumptions used as part of this method of determining development viability are:
• Benchmark land value;
• Gross Development Value (GDV);
• Developer return;
• Construction/development costs; and
• The costs of policy compliance.
