About these images. AI concept The right-hand images were generated with AI tools. They are illustrations of the kind of building our proposed design rules would allow, not proposals for these specific properties, and we have not consulted the owners. Cost figures are conceptual hard-cost budgets in October 2026 dollars per above-grade gross square foot (GSF), excluding land, parking, soft costs and financing. See the cost study for scope and caveats.
