Generally Accepted Process

Non-verified recycled, reused and urban salvage.

Toughened Glass


Choices for Bull Street

Clear Finish Grade Australian timbers (limited use of paints, laminates and other coatings)

FSC (Forest Stewardship Council) certified timber

Recycled timber

Recycled Toughened Glass

Summary of Reasons

Laminates. The Living Building Challenge Red List prohibits the use of products containing added formaldehyde. At present there is no Australian produced laminate timber, such as plywood or MDF, produced without formaldehyde. Products classed as E0 will still have formaldehyde content – < 0.05% pm3.

Timber acquired from a main stream lumber yard in Australia will be from varied sources, some highly questionable, unless it is clearly specified otherwise. AFS certification is usually the best certification on offer, but is not nearly stringent enough. AFS certification is NOT adequate assurance alone; it can be Australian native old growth forest timber, or uncertified plantation, cleared from native forest after 1994, this certification also has NO restrictions on biological pesticides and GM products. In the Greenpeace Good Wood Guide AFS standards are NOT enough to qualify timber as even ‘Amber’ level wood. Whereas FSC accreditation satisfies that it is a ‘Good Wood’ product.

Imported Asian timbers (for example Merbau) is suspected of having up to 80% illegal content. Any rainforest destruction is devastating to irreplaceable ecosystems. Illegal, un regulated rainforest timber is catastrophic. It is impossible to guarantee tropical hardwoods are 100% legal so we have decided to find Australian alternatives which we can verify.
