(c) have a ramped threshold that—
      (i)    does not exceed 56 mm in height; and
      (ii)   has a gradient not exceeding 1:8; and
      (iii) is at least as wide as the minimum clear opening width of the entrance door; and
      (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.
