2 Development assumptions

Greenfield / land project Society redevelopment Joint venture / landowner partnership

Primary project type Commercial componentCommercial carpet, including shops, is capped at 15% of total project carpet. Shops are capped at 25% of net plot area; the balance is treated as offices. Special FSI pathway Green-building incentive Indicative building height

Used for the fixed construction-cost schedule and the floor-band median sale-rate model.

For a residential mixed-use project, the engine targets 15% final commercial carpet. Where 60% residential and 80% commercial ancillary apply, it back-solves the principal-area split before using the same 85% carpet conversion for each portion. Special pathways remain conditional screens, not automatic entitlements.

3 Ready Reckoner, market and construction

Land RR and RR construction/unit rates are obtained from the survey-number match. Residential and office sale rates use height-weighted registered floor-band medians after the high-outlier screen. Shop rate is the higher of its screened registered median or twice the residential/main-use rate.

Useful for comparison. Not a substitute for project due diligence.

The free report states every adopted assumption, separates FSI components, shows registered-data guidance, calculates the development programme, tests finance and provides a nine-cell sensitivity table.
