Business case insight

Vellum combines generative design with planning data, leading to real time insight of your business case​.

  • All generated designs are linked to cost benefit calculations in a format that you are familiar with.

  • Use standardised cost items or specify your own for eg. building costs, advisor costs and expected profitability.

Suddenly had an idea for a different parameter? Go back to generating new options based on your new insights. The whole process allows you seamless transitions between generating concepts to analysing returns, all on a single platform.
