How can you deliver housing below market rates? That seems unrealistic.

The economics work because of our unique SEZ/CLT (Special Economic Zone/Community Land Trust) combination and the scale of development. At city scale, the value uplift from commercial acreage is exponentially larger than in smaller developments. This commercial value can cross-subsidize residential prices in ways impossible for traditional town developments. Additionally, greenfield development eliminates the expensive land acquisition costs that plague town extensions, where compulsory purchase of existing developed land drives up costs significantly.
