Plot Width for Irregular Plots

For plots of irregular shape within existing landed housing estates, slight deficiency in the required plot width for semi-detached housing may be considered provided:

  • The average width of the site remains at least 8m so as to allow for a meaningful building footprint and internal layout;

  • The absolute minimum plot width at its narrowest shall be 4m;

  • The plot shall fully comply with the minimum plot size control and all other development control guidelines e.g. setback, road buffer, etc.

Examples of irregular-shaped plots allowed

The deficiency in plot width, if allowed, shall be restricted to one plot per development and shall be a residual plot (i.e. all other plots within the same development shall comply fully with the minimum plot width).
