Table 2 : Maximum Domestic Plot Ratios - New Towns (excluding Tsuen Wan)

[Table Summary]

Residential density zone
Maximum domestic plot ratio
8 (i) (ii) (iii)
R4 (iv)


General : The Table only gives an indication of the maximum plot ratio which may be allowed for a particular area. However, where there are significant constraints on development capacity (such as transport or infrastructure limitations, environmental, topographical or geotechnical conditions, or heritage and nature conservation), other planning principles and urban design considerations (including local character and setting, building height profile and massing of the neighbourhood, air ventilation and visual impacts on the surroundings, protection of important physical features such as ridgelines), or special design considerations, a lower plot ratio may be specified when considered appropriate and possible.

(i) Domestic plot ratio 8 should only be permitted where there are no infrastructure constraints, e.g. close to high capacity transport systems. Elsewhere, the plot ratio should be determined according to local circumstances. A maximum permitted plot ratio for R1 in most New Towns is 6, where infrastructural capacity and planning considerations permit.

(ii) In the first generation New Towns (i.e. Tuen Mun, Sha Tin, Fanling / Sheung Shui, Tai Po, Yuen Long and Tsuen Wan), lease modifications for higher plot ratios than those applicable prior to September 1981 should be permitted only if the proposed development forms the whole or a substantial part of a comprehensive redevelopment plan prepared or approved by the planning authority.

(iii) If there is non-domestic floor space, maximum domestic plot ratio will be reduced according to the provisions of the B(P)R composite building formula.

(iv) Sites in New Towns should only be designated R4 if there are special justifications such as severe geotechnical or infrastructural constraints.
