These are the articles and web sites I found usefull while researching my major assignment

CSR Gyprock

Especially good for wall and cieling detailing. The Red Book is an all in one brochure, which I obtained a copy of from their office in Fyans St. It is also available online.

Bluescope Steel

Gave a wide range of roofing profiles from which I chose.

Timber Building in Australia

Very useful on the subject of Portal frames. Used along with the Timber Manual I found in the library which gave me more detailed joining techniques. They did however provide some conflicting information, especially regarding how to construct the knee joint.

Boral Timber Products
http://www.boral.com.au/
Gave options for how to construct the timber decking and ballustrade
