  • (a) the floor load on suspended floors shall not exceed:
    • (i) 1.5 kPa or 2 kPa in balconies only, for buildings more than one storey in height;
    • (ii) 3 kPa for one storey in height only where the provisions of this Code are modified by Appendix H.
  • (b) Buildings shall be Category IV buildings as described in table 2.3.1 of NZS 4203.
  • (c) The total height from the lowest ground level to the highest point of the roof shall not exceed 10 m.
  • (d) Single storey buildings which may include a storey height basement or a half storey floor area in the roof space to comply with 4.1.2 shall be a building supported on any combination of the following foundation structures:
    • (i) piles,
    • (ii) foundation walls,
    • (iii) concrete slab-on-ground.
  • (e) Two storey buildings consisting of not more than two suspended timber floors shall be supported on foundation wall structures and piles or braced piles complying with section 4 or one suspended floor above a concrete slab-on-ground, or full storey height concrete masonry wall or including a foundation wall with an upper storey of timber.
  • (f) Three storey buildings shall consist of no more than two storeys supported on timber framing, one of which shall be a part storey in a roof space, all supported on a full storey height on continuous reinforced masonry walls and foundation walls to the provisions of NZS 4229. The ground floor may be a concrete slab-on-ground or a suspended timber floor within the masonry walls. 
  • (g) The slope of any roof plane shall not be steeper than 60 degrees to the horizontal.
  • (h) The design wind speed for buildings for different exposures are listed.
  • (j) The snow load as specified by NZS4203 shall not exceed 0.5 kPa, provided that where the snow load exceeds 0.5 kPa but does not exceed 1.0 kPa, Appendix J shall apply.
  • (k) Each part of the building shall be within the limitations stated or implied by the relevant clauses or tables of this Standard.
  • (m) The plan floor area shall:
  • (i) be unlimited for buildings where all storeys are of timber frame,
  • (ii) not exceed 300 square metres for two storey buildings where the upper storey is of timber frame and the external walls of the lower storey are of reinforced concrete masonry,
