DESIGN BRIEF - SOUTHERN AREAS
1.01
Scope
This brief sets out guidelines for the design of GROH rental accommodation and site-works in
the Southern Areas of the State as shown on the attached map.
1.02
Mandatory Constraints
a)
Generally
All designs should comply with all relevant Federal, State, Local Government and
service Supply Authority laws, by-laws and regulations and Building Code of
Australia in conjunction with the Government Regional Officers’ Housing (GROH)
Specification.
b)
Standards
Design should be in accordance with all relevant Australian Standards and, in the
absence of an appropriate Australian Standard, consider and apply the manufacturer's
recommendation.
c)
Australian Materials
Except where specified otherwise in this Brief, Australian and New Zealand Materials
shall be used. Overseas materials shall not be used unless approved by the
Department of Housing and Works, after assessment in accordance with the National
Preference Agreement.
1.03
Housing for the Disabled
GROH when required provides assistance for government employee’s with disabilities.
Specific individual requirements for this client group will be supplied to the panel of specialist
disability Architects to incorporate these requirements into the design.
If the project Architect responsible for the whole site is not providing the design for the specific
disability requirements then they will modify floor plan and site layouts as instructed by the
Project Manager (Disability).
The requirements of units provided for people with disabilities will be individually specified
within the Project Brief.
1.04
For designs and / or documentation prepared for the Department of Housing and Works /
GROH, the copyright in drawings, specifications and other documents remains the joint property
of the Designer and the Department of Housing and Works. The Department of Housing and

UNIT DESIGN, PLANNING & ACCOMMODATION
3.01
Scope
This sub-section sets out guidelines for the design of accommodation.
3.02
Generally
(i)
The site plan is to show the following information:
















House type (to be nominated in the outline of the house)
Existing ground levels, contours and features (including adjoining property levels
at existing boundary’s).
Finished floor levels of the house, carport and driveway.
Position of septic system.
Location of all existing trees / vegetation to be retained or removed.
Extent of cut and fill and embankments with finished ground levels.
Extent and height of new retaining walls.
Extent of new paving including driveway and crossover.
Extent and height of existing fencing and whether it is intended to remove it.
Extent of new fencing and gates.
Location for water meter and consumer pole position.
Location of the clothes hoist.
North Point and scale.
Location and invert level of sewer and any encasements (if available).
Fronting road location showing level and surface.
Location of reticulation sleeves.
(ii)
Economics: The unit layout and siting of units within the lot should achieve an
effective use of space using the economics of the construction system as much as
possible, the use of economic and standardised components minimising cutting and
wastage.
(ii)
Identity/Personalisation: Particular attention should be paid to providing an attractive
street elevation for each dwelling with its own identity and some potential for
personalisation by the occupant.
(iii)
Flexibility: The planning of the dwelling should, where possible, allow the
development of private external living areas,
(iv)
Natural Lighting: Should be maximised (without direct sunlight) to all rooms so as to
allow their use during the daylight hours without artificial lights.
(v)
Natural Ventilation: The position and size of window openings should permit crossventilation. Artificial ventilation is to be avoided.
(vi)
Solar Design: Passive solar design techniques (particularly the shading of walls and
especially windows) should be maximised. The position and depth of external
covered areas and wing walls in relationship to windows and expected orientation
should be considered. All designs shall achieve a optimum energy effectiveness
through orientation, shading, ventilation and insulation.
(vii)
Colour Schemes:
The Department of Housing and Works standard internal colour schemes are to be
used unless the Project Manager approves the use of an alternative scheme.
Internal/external colour schemes to be submitted to the Project Manager for approval.

(viii)
Design Documentation:
The internal dimension all rooms, verandahs, patio’s and carports is to be shown.
External wall dimensions, corner to corner to be shown.
GROH BRIEF SOUTH
(vii)
Planning:
-
Lounge and sleeping areas are to be separated.
-
Bathroom and W.C should be accessible to the bedrooms without the need to pass
through the living areas.
-
Main Entry: The lounge area should retain privacy from entry.
-
Maximise size of Dining/Family room which should have direct access to private
outdoor Living Areas.
-
The Lounge Room is to be separate from the Dining/Family Area to create two living
spaces.
-
Laundry: convenient access from both inside and outside the building. The laundry is
to be provided with a door to isolate it from the remainder of the house.
-
Kitchen work areas should be outside main circulation routes.
-
Access for the removal and installation of furniture should be provided for all rooms.

Method of calculating dwelling area.
3.03
Gross Floor Area (G.F.A.)m²
which is made up of:
1.
Comparative Dwelling Fully Enclosed Covered Area (CD FECA)m² = 'A' measured to the normal
inside face of external wall. Note that Comparative Dwelling FECA does not include the area of
the stores under the main roof to enable direct comparison of dwelling areas of units with and
without stores.
2.
Covered Enclosed Store Area m² = 'B'
3.
Unenclosed Covered Area (U.C.A.)m² = 'D' Area under the main roof being porches, carports,
verandahs.
4.
Building Area (B.A.)m² = 'C' measured to the external face of the external wall of the building.

Optimum Dwelling Area
Each dwelling design should have approximately the optimum "Comparative Dwelling F.E.C.A." listed below.
Dwelling F.E.C.A. means the sum of all fully enclosed covered areas of all the dwelling unit floor levels computed by
measuring from the normal inside face of exterior walls and walls dividing dwelling units.
It shall not include open courts, covered ways and net open areas of upper portions of rooms or spaces which extend
through the storey being computed.
Comparative Dwelling F.E.C.A. means the Dwelling F.E.C.A. minus the area of the floor and internal dividing walls
of the store room measured at floor level.
The unit of measurement for F.E.C.A. is square metres (M²).

SITE PLANNING
4.01
Scope
This sub-section sets out guideline for the design of siteworks.
4.02
Generally Site planning shall comply with the requirements of the Local Authority.
Particular attention should be given to the visual quality of the development from the street, so as
to achieve a continuity of form and style without monotony, yet still retaining identity of each
dwelling.
4.03
Density
Design to maximise the density on site, including density bonus for one-bedroom units if
applicable, or as directed by the project brief.
4.04
Privacy
The positioning of a dwelling on a site whether as a single unit or as a group of units should
ensure privacy from over looking of outdoor living areas, entry, habitable room windows and
dining areas.
4.05
4.06
Sense of Address - Multi Unit Developments
(i)
Visual: Each dwelling should have a "sense of address" to the street or access way,
with the unit’s principal entry readily identifiable.
(ii)
Numeric: Each dwelling, letterbox, and letterbox group, should be clearly identified
by a 50mm high metal unit and/or street number visible from the street or access way.
(In accordance with Homeswest numbering systems).
(iii)
The Superintendent is to obtain the correct identifying street number from the Local
Government Authority.
Service and External Living Areas
Siting should create separate service and external living areas. Each area should have a direct
link with their corresponding internal spaces (i.e. living/dining rooms to external living areas and
laundry to service court).
The layout of the private yard shall be such as to maximise the unobstructed areas available for
playing and should include the patio area.
4.07
Maintenance of External Open Space
In grouped housing developments open space should be designed to provide each unit/tenant
with a clearly identifiable area of garden space which the tenant can be responsible to maintain.
The allocation of garden space to tenants should be maximised so as to reduce GROH’s
maintenance costs. Particular attention should be given to the clear demarcation of unfenced
private ground space and adjacent communal open space.
4.08
Floor Level/Contour
The relationship between a dwelling, neighbouring buildings and ground contour should be
carefully considered. In general the floor level should be kept as low as possible while still
maintaining a sense of continuity with adjoining dwellings.
Floor levels are to be 150mm minimum above finished ground level and conform to Local
Authority requirements.
GROH BRIEF SOUTH
23
JAN 2009
4.09
Cut and Fill/Retaining Walls
Where units are to be built onto sand pads the compacted surface area of the pad shall extend
beyond the building external walls for a minimum distance of two metres and graded away from
the footing / wall at 1:10 maximum slope.
Provide retaining walls at boundaries where there is a difference or greater than 150mm between
finished ground level within the site and existing adjacent ground levels of the neighbouring lot.
Where retaining walls are required on a boundary the fencing is to be erected on the high side of
the retaining wall.
The whole of the site shall be cleared of surplus soil or debris (except for suitable trees) which
must be removed from the lot.
Filling Material: Clean sand free of clay and debris is to be used to bring the lot to a suitable
finished ground level.
4.10
4.11
Orientation
(i)
Sun: (of primary importance): The main axis of the dwelling should be, where
possible, within the 15o of the east-west axis. Windows of habitable rooms preferably
should not be placed on the western and eastern elevations unless fully shaded.
(ii)
Wind: (of secondary importance): Windows and door openings should, where
possible, be orientated to maximise the cross ventilation of rooms by prevailing
breezes.
(iii)
View: (of secondary importance): Windows of habitable rooms should, where
possible, be orientated to exploit views.
(iv)
All designs should have the best orientation to achieve the lowest energy use.
Vegetation
Avoid the removal of any existing trees which are likely to have a long life and which will not
interfere with the building structure or services. Access to gates is to be clear of trees.
4.12
Building Line
The dwelling should be sited by, utilising set backs to within the scope of the R codes to provide
variation in streetscape.
4.13
