Introduction
Background
This ABCB Standard provides a set of technical provisions that if complied with will enable dwellings to better meet the
needs of the community, including older Australians and people with mobility limitations.
This ABCB Standard has been adapted from the ‘Silver’ level requirements of the Livable Housing Design Guidelines
(LHDG), fourth edition, 2017, which were first published by Livable Housing Australia.
It is important to note that this ABCB Standard is not an exact replication of the LHDG. There are instances where
adjustments have been made in order to convert the LHDG — which was drafted as a voluntary guideline — into a
document suitable for use as a regulatory standard. There are also instances where adjustments have been made in
response to stakeholder feedback provided through one or more of the consultation processes that occurred in the
development of this document.
Scope
This ABCB Standard is intended as a set of minimum necessary provisions, rather than as an exemplar of best practice.
This is consistent with the role of the National Construction Code (NCC) which calls up this ABCB Standard.
This ABCB Standard is not intended for use in designing specialist accommodation, nor is it intended to achieve
equivalence with AS 1428.1. Therefore, its provisions may not accommodate the needs and abilities of all home occupants.
Nonetheless, the features described herein are considered to be of most widespread benefit and use in the majority of
T
circumstances.
AF
Application
In this ABCB Standard, generic references are made to ‘dwellings’. The specific application of this ABCB Standard to
particular types of dwelling is determined according to the particular regulation or guideline in which the ABCB Standard
may be referenced.
DR
In general, the provisions of this ABCB Standard are designed for application to Class 1a buildings (houses and the like)
and Class 2 sole-occupancy units (apartments), as defined in the NCC.
This ABCB Standard is referenced in the Deemed-to-Satisfy Provisions of Part G7 of NCC Volume One and Part H8 of
NCC Volume Two.
The ABCB will also publish a non-mandatory version of this ABCB Standard based on the LHDG ‘Gold’ level requirements,
which can be applied on a voluntary basis to achieve a higher level of livability.
Terms with a specific meaning
In this ABCB Standard, terms shown in italicised text have the meaning that they have in the NCC.

(iv) does not intrude into the minimum dimensions of a landing area that is required by Clause 2.3.
Information Water ingress
For slab on ground construction, NCC referenced document AS 2870 requires a minimum slab height of 150 mm above
finished ground level. However, AS 2870 also allows this height to be reduced to 50 mm at door openings if an adjoining
paved surface slopes away from the building, and further reduced if the door opening is shielded from the weather.
This reduced height enables a ramped threshold to be used as part of a Deemed-to-Satisfy Solution under the NCC.
Information Termite management
For termite management, where required by the NCC, the NCC referenced document AS 3660.1 includes solutions for
termite management in cases where there is no step-up into a dwelling: see clauses 2.2, 2.3, 4.4 and 6.5 of AS 3600.1.
AS 3660.1 is referenced in the NCC, therefore an appropriate solution for termite management that complies with AS
3660.1 can be used as part of a Deemed-to-Satisfy Solution under the NCC.
2.3 Landing area
T
1. An entrance door that is subject to Clause 2.1 must have a space of at least 1200 mm x 1200 mm on the external
(arrival) side of the door that is—
AF
a. unobstructed; and
b. level, or has a gradient not exceeding 1:40 if a gradient is necessary to allow for drainage.
2. The space required by (1), but excluding any ramped threshold provided under Clause 2.2(c), may overlap with the
same space serving the entrance door of another dwelling.
DR
Applications
Clause 2.3 only applies to a Class 1a building.
Information Entrance doors to Class 2 sole-occupancy units
Requirements for landing areas outside the entrance door to a Class 2 sole-occupancy unit located on an accessible
floor are set out in Section D of NCC Volume One and the Disability (Access to Premises — Buildings) Standards 2010.

Part 4 Toilet
4.1 Location

Information
The term sanitary compartment refers to a room or space containing a toilet. It applies equally to any type of room or
space containing a toilet, such as a bathroom, ensuite, powder room or other separate room. It is used in place of the
word ‘toilet’ for consistency with the wording of the NCC and to avoid confusion with the use of the word ‘toilet’ to refer
to a plumbing fixture rather than the room in which that fixture is located.
4.2 Circulation space
A sanitary compartment that is subject to Clause 4.1 must be constructed in accordance with the following:
(a) For a toilet located in a separate sanitary compartment, there must be a clear width of not less than 900 mm between
the finished surfaces of opposing walls either side of the pan.
(b) For a toilet located in a sanitary compartment that is combined with a bathroom, the pan must be located in a corner
such that—
T
(i) the wall adjacent to the pan incorporates the reinforcing required by Clause 6.1; and
(ii) the centre-line of the pan is between 450 mm and 460 mm from the finished surface of the wall referred to in (i).
AF
(c) If a door used to access the sanitary compartment swings inward, a minimum circulation space of 1200 mm must be
provided from the front edge of the pan to the swing arc of the door to the sanitary compartment.
(d) Compliance with (a), (b) and (c) must be determined in accordance with Figures 4.2a and 4.2b.

Part 5 Shower
5.1 Application
At least one shower within the dwelling must comply with each of the applicable clauses in this Part.
Information
The intent of Clause 5.1 is to ensure that the same shower has all of the required features, rather than, for example,
one shower in the dwelling having a hobless entry and a different shower having the required circulation space.
“At least one shower” means that in a dwelling with two or more showers, only one of the showers needs to comply
with the requirements of this Part.
5.2 Hobless and step-free entry
1. At least one shower must have a hobless and step-fee entry.
2. A lip not exceeding 5 mm in height may be provided for water retention purposes if it is constructed in accordance
with the specification given in Clause 3.13.4 and Figure 3.6 of AS 3740.
T
Information Hobless and step-free
Clause 5.2(1) refers to a shower entry being ‘hobless’ and ‘step-free; because those two terms have different meanings.
AF
A shower where the floor within the shower compartment is level with the floor adjacent to its entry would be ‘step-free’
but could still have a hob. Conversely, a shower with a step-down into the shower recess does not have a ‘hob’ (i.e.
‘hobless’), but would not be ‘step-free’. Therefore, to achieve the intent of Clause 5.2(1), it is necessary to specify that
the shower is both ‘hobless’ and ‘step-free’.
DR
Information Waterproofing
AS 3740 includes specific requirements for waterproofing a hobless, step-free shower area. AS 3740 is referenced in
the NCC Deemed-to-Satisfy Provisions for general waterproofing of wet areas.
5.3 Shower screen
1. The shower screen door (if provided) must be capable of removal without causing damage to adjoining parts of the
shower enclosure.
2. For the purposes of AS 3740, the bathroom floor must be graded as if the shower were an unenclosed shower.
Information Floor grading
AS 3740 includes specific requirements for grading of floors in and around an unenclosed shower.
