Mandatory front/rear open margins required by local Development Control Rules (DCPR).
Formula Notice: For plots with unequal opposing boundaries, the calculation utilizes the average end-lengths method: $\text{Avg Width} \times \text{Avg Depth}$. For plots with sharp diagonal skews, triangular surveying with diagonal offsets is recommended.
