Building Area Calculator
Sums floor area from up to 4 floors, each approximated as up to 2 rectangles (for simple L-shaped footprints). The total only includes floors you mark "include in total".
ℹVerify locally before acting. This tool is a planning and arithmetic aid, not a substitute for training, local SOPs, calibrated instruments, or scene assessment. Confirm critical values independently. Suite status: DRAFT - not yet department-approved for operational use.
When you'd use this: Pre-planning a commercial building with an irregular, L-shaped footprint - break each floor into two rectangles to get a reasonably accurate total area to feed into a required-fire-flow calculation.
