Note:

*To facilitate the submission of addition and alteration applications, we will accept development applications showing the additions and alterations of the affected areas only. With the exception of cases that require the recomputation of gross floor area, no other details are required for the remaining development except for the building outline only (Please see example provided in Guidelines For Submission of CAD Files To URA (PDF, 133KB).)

SAMPLE PRESENTATION ON SITE COVERAGE (Applicable only to detached houses)

Site coverage means the area of all buildings or structures measured along the outermost external walls where the roof projection is equal or less than 2.0m, expressed as a percentage of the nett site area (excluding road and drainage reserve, if any).

For roof eaves wider than 2.0m, a 2.0m width from the roof eaves will be excluded from site coverage computation.

Please therefore verge the outline accordingly.

Control:

Within Good Class Bungalow Area	:	35%
Outside Good Class Bungalow Area	:	40% (for plots > 800 m²)
	:	40% (for plots < 800 m²)
	:	45% (for plots < 800 m²) - Applicable to 2-storey mixed landed and 2-storey semi-detached housing areas

Note : The eave line must be reflected in the calculation plan.

Calculation by parcellation
1) Area with roof eaves projection > 2.0 m
A	= 3.1 m	x	3.0 m	= 9.3 m²
B	= 0.4 m	x	5.0 m	= 2.0 m²

2) Area under roof eaves projection < 2.0 m
C	= Exempted
D	= Exempted

3) Area with roof eaves projection < 2.0 m
E	= 2.8 m	x	2.0 m	=5.6 m²

4) Area with no roof eaves
F	= 25.0 m	x	9.0 m	=225 m²

5)
i	Total covered area		= 241.9 m²
ii	Net site area		= 800.0 m²
iii	Site coverage		= 241.9 x 100
			800
			= 30.24 %
