请教一个问题，公共区域的面积算在容积率么？

应该不算吧只算能卖的size

URA官方不都有解释么 ??

In line with the principles mentioned, the following are additional areas not counted as GFA:

a. Covered linkways, pavilions and sheds

This refers to covered open-sided linkways and pavilions/sheds (with no commercial use) incorporated as part of landscaping provided these structures are located outside and detached from the main buildings and the linkways are designed as connections between buildings and/or facilities at the 1st storey level.

b. Basement diaphragm walls

Such walls are built along the periphery of the site and are usually required to meet structural conditions in basements.

c. Curtain wall or cladding systems

For buildings with curtain wall or cladding systems fixed onto the main structure, the GFA shall be measured up to edge of the main structural floor slab. However, if there are external walls, the GFA shall be measured up to the thickness of the external walls excluding the curtain wall or cladding systems.

d. Left over spaces in car park floors

This refers to all left over spaces like pedestrian walkways, pavements, planting boxes and residual areas (including areas enclosed on 3 sides regardless of shape or size) arising from the layout of parking lots. However, enclosed staircases, loading/ unloading platforms, stores, toilets, lift lobbies will continue to be counted as GFA.

e. Covered public footway/walkway

This applies only to covered footway/walkway facing any existing or proposed public road, public pedestrian mall, public open space/landscaped area or which links 2 public areas and where such footway/walkway is required by the Competent Authority or other Government agencies to be kept open at all times for public use as part of the public pedestrian network.

f. Certain covered public concourse area

This refers to areas provided voluntarily at the 1st storey level of a building in an office or main shopping or hotel development if the covered public space meets all the locational, urban design and development control criteria spelt out in　Appendix 1.

g. Roof concealing unsightly roof-top equipment

This refers to the space under a roof to conceal unsightly roof-top equipment provided there is no direct access via a common staircase to the roof top. This is to ensure that the space is not used for other purposes.

h. M&E spaces with limited headroom (ie less than 1.5 m)

This includes pump room, crawl space for maintenance access and cable chamber. For cable chamber, if the height of the ESS and the cable chamber exceed the 1st storey height control, the cable chamber would not be counted as GFA if it can be justified that a higher ESS is a PUB requirement. If this is so, PUB's certification is necessary.

i. Roof-top or other uncovered landscape gardens, tennis courts, swimming pools, private enclosed spaces, balconies

With these areas now not counted as GFA, the criterion of exclusive private use (eg by means of strata boundary) as a basis to determine GFA no longer applies except for air wells/open courtyards of shophouses which will continue to be treated as GFA.

j. Ledges for air-conditioning units and planters

k. Suspended AHU in voids

These are suspended and supported by metal brackets or beams within voids. They are regarded as equipment and not structures per se.　
l. Rainwater holding tanks buried in the ground, aesthetic mouldings, unroofed staircases to ESS, meter compartment /bin point at gate post, non-weather proof building maintenance platforms at roof level The following areas are however partially counted as GFA:

a. Lift shafts

Lift shafts to be counted once for single lift cabin, twice for double lift cabin in double decker lifts. This is applicable to normal, express and bubble lifts.

b. Vertical service duct space
These service ducts, like lift shafts, to be counted once provided the vertical space is hollow. If the service ducts are slabbed over, they will be treated just like any other floor space to be counted as GFA.

c. Lift lobbies in car park floors
GFA is limited to an area equivalent to the size of the lift shaft or to the actual size of the lift lobby, whichever is smaller. This is intended to provide flexibility in design and ease of computation.
