These walls were made from just sand and cement

The site where we were building the garden had a very sandy soil so we just used the sand from the site.

The soil benind the wall was amended with large quantitiies of compost and rock dust to make it fertile and improve water retention

I have learnt how to make the moulds cheaper and easier to build.
If you do not want to take the corners off the beds then all you need is
2 planks [12 x 2  inches ] and can be any length but I normally use 2.5m
2 iron braces
2 wooden wedges

The iron braces are the genius of the design

Now if you want to get fancy then you can build the end walls as shown in the third picture which involves cutting compound angles and using hinges

But if you want to use the moulds in a more flexible way then do not any hinges and only to make simple saw cuts on short pieces of plank as shown in pictures 4 and 5.

Keep the wall shutters apart with 2 iron braces and wooden wedges
This allows you to make circles and wiggly walls

I no longer use this Hinge Board and have found a couple of wooden wedges are all you need to keep the Wall Shutters apart before you start ramming in the concrete

These photos were taken at Koanga Gardens, and demonstrates the alfresco possibilities of combining Raised Bed Gardens, Pizza Ovens, Kids Play Huts, Compost Toilets and Hybrid Adobe Walls for shelter and warm.

Indoor and outdoor spaces are a continuum

Dome shaped play hut made of bent over branches and stick plastered with a paper adobe mix called Hybrid adobe, eg pulped paper 50%, clay 30%, sand 10%, cement 10%
