(1) The Deemed-to-Satisfy Provisions of this Part apply to buildings containing an occupiable outdoor area in addition to the other Deemed-to-Satisfy Provisions of NCC Volume One.

(2) The Deemed-to-Satisfy Provisions of this Part take precedence where there is a difference to the Deemed-to-Satisfy Provisions of Sections C, D, E, F and G.

(3) Except for G6D2, the Deemed-to-Satisfy Provisions of this Part do not apply to—

  1. an occupiable outdoor area of a sole-occupancy unit in a Class 2 or 3 building, Class 9c building or Class 4 part of a building; or
  2. an occupiable outdoor area with an area less than 10m2.

Explanatory information

Part G6 contains Deemed-to-Satisfy Provisions additional to those contained in Sections C, D, E, F and G for occupiable outdoor areas.
