  BU546 House Condition Survey - external envelope

BU546.jpgThis bulletin describes findings from the 4th BRANZ House Condition Survey, conducted between July 2010 and February 2011 and covers the external condition of 494 New Zealand houses.

The BRANZ survey is the only systematic survey of this scale of the structure, type and condition of New Zealand dwellings. For the first time, a nationwide sample was taken, and rental properties are included.

Houses typically had at least one component in poor or serious condition. The most common building envelope defects included:

  • poor subfloor ventilation
  • inadequate clearance of wall claddings from the ground
  • poor or missing subfloor fasteners.
