NZS 3604:1999
Timber Framed Buildings
Provides suitable methods and details for the design and construction of timber framed buildings up to three storeys high. This standard is intended to apply to domestic dwellings, most residential and some commercial and other buildings, without the need for specific engineering design. Supplied as hole-punched pages together with a ring binder. Reprinted to incorporate Amendment 1 and 2.
