(2) Subject to regulations 19A and 22, the plot ratio for the
domestic part of a composite building shall not exceed the product
of the diffierence between the permitted plot ratio for the building if
it were a non-domestic building and the actual plot ratio of the
non-domestic part of the building and the permitted plot ratio for
the building if it were a domestic building divided by the permitted
plot ratio for the building if it were a non-domestic building.

(3) For the purposes of this regulation and of regulations 19,
20 and 22, the plot ratio of a building shall be obtained by dividing
the gross floor area of the building by the area of the site on which
the building is erected.





22.(1) Where, between ground level and a height of not less
than 5m or, where the Building Authority is satisfied that there will
be no obstruction to vehicular traffic using the street. 3.3 m above
ground level. a building on a class A. B or C site is set back from a
boundary of the lot on which it is erected, being a boundary that
abuts on a street, and. with the consent of the Government, the part
of the lot that is thereby not build upon is dedicated to the public for
the purposes of passage-

(a)the site coverage for the building or for any one part of the
building may exceed the permitted percentage site cover-
age, so, however, that the site coverage therefor does not
exceed that percentage of the area of the site equal to the
sum of the permitted percentage site coverage for the build-
ing or for that part of the building. as the case may be. and
the figure obtained by dividing the product of 1 500 and
the area of the lot so dedicated to the public by the product
of the area of the site and the height of the building; and

(b)the plot ratio for the building or. if the building is a
composite building, for the domestic part of the building
may exceed the permitted plot ratio, so. however, that the
plot ratio therefor is not greater than the permitted plot
ratio for the building or for that part of the building. as the
case may be. by more than 20 per centum or does not
exceed 61e surn of the permitted plot ratio for the building
or for that part of the building. as the case may be. and the
figure obtained by dividing the product of 5 and the area of
the lot so dedicated to the public by the area of the site on
which the building is erected. whichever is the less.

(2) Where part of a lot, being a part that abuts on a street, is
acquired by the Crown. either by agreement or by resumption under
the Crown Lands Resumption Ordinance. for the purpose of street
widening, the Building Authority may permit-

(a)the site coverage for a building erected on that lot. being a
class A. B or C site. or for any one part of the building to
exceed the permitted percentage site coverage, so, however.
that the site coverage therefor does not exceed that percent-
age of the area of the site equal to the sum of the permitted
percentage site coverage for the building or for that part of
the building. as the case may be. and the figure obtained by
dividing the product of 1 500 and the area of the part of the
lot so acquired by the Crown by the product of the area of
the site and the height of the building: and

(b)the permitted plot ratio for the building or. if the building
is a composite building. for the domestic part of the build-
ing to exceed the permitted plot ratio. so. however. that the
plot ratio therefor is not greater than the permitted plot
ratio for the building or for that part of the building. as the
case may be, by more than 20 per centum or does not ex-
ceed the sum of the permitted plot ratio for the building or





for that part of the building, as the case may be. and the fig-
ure obtained by dividing the product of 5 and the area of the
part of the lot so acquired by the Crown by the area of the
site on which the building is erected, whichever is the less.

(3) For the avoidance of doubt. it is hereby declared that-

(a)where under paragraph (1) or (2) the permitted percentage
site coverage is exceeded in relation to a part of a building.
the site coverage for any other part of the building shall not
exceed the permitted percentage site coverage;
(b)nothing in this regulation shall be taken or construed as
derogating from the provisions of regulation 25 as to the
amount of open space to be provided about a domestic
building.

(4) In this regulation, the expression ---permittedpercentage
site coverage- means the maximum site coverage permitted under
paragraph (1) or (2), as the case may be. of regulation 20.

different levels. from the mean level of the lower or lowest
of the streets to the mean height of the roof over the
highest usable floor space in the building;
(b)the gross floor area of a building shall be the area con-
tained within the external walls of the building measured at
each floor level (including any floor below the level of the
ground) to ther with the area of each balcony in the

sions of the balcony (including the thickness of the sides
thereof), and the thickness of the external walls of the
building; and

(c)a street that is less than 4.5 m shall be deemed not to be a
street.

(2) In determining for the purposes of regulation 20, 21 or 22
the area of the site on which a building is erected-

service lane; and

(b)there shall be included any area dedicated to the public for
the purposes of passage.

(3) In determining for the purposes of regualtion 20, 21 or 212
the gross floor area of a building, the Building Authority may take
