ARK Design AI
Ark Design AI automates floor plan generation and feasibility studies for multi-family and mixed-use development. It optimises unit mix for density, profitability and living standards, checks against local building code and ordinances for US projects, and produces area tables and feasibility reports. It holds a US patent.
- Automates the stage of development work that is most often discarded, which is exactly the right target
- Testing twelve configurations instead of one is how a viable scheme actually gets found
- Automatic area schedules remove both manual arithmetic and drift between drawing and financial model
- Code checking catches the constraint problems that otherwise surface expensively late
- Automated code checking is a first pass, not a determination, and the site does not draw that line firmly
- US-only code coverage, with the specific jurisdictions not enumerated anywhere we could read
- Code data update frequency is not stated, which matters because ordinances change
