AW: [Strawbale] concrete footings

[Ruth Walker]

Hello,

Have you thought of Rammed tyres (with roadstone/scalpings). Tyres are 
free and would otherwise go to landfill. Depending on your soil 
conditions you can have no foundations under them ate all.  Have a look 
at Amazon Nails site and/or read Barbara Jones book for more details.
