Subject: Re: Superwood
Superwood's density is around 1.25 g/cm³ (1250 kg/m³)—about three times as dense as regular wood.

Steel, by contrast, has a much higher density: approximately 7.85 g/cm³ (7850 kg/m³)

So, depending on which end of the range is used, Superwood is between the same and double the cost of steel for the same volume of material (though, since it is far weaker than steel, more of it would have to be used for equivalent strength.

That's why architects (should) use engineers.
