looks very promising.
i'll have to spend time on the website.

wil and chris dancey (tfg members and dietrich's NA reps) used a hemp lime infill system on their home in ontario. came out wonderful... they formed up between timbers and then did various plaster finishes.

lots of labor for sure. a block version would be a big help... except for trucking across country to your local site.

i've often thought a great way to start using some of these alternatives would be to set up a hoop house and throughout the summer (whilst other building activities were ongoing) you could press blocks of hemp lime or straw clay or woodchip clay. if done well a press set up to a known PSI could get the block consistent... and then stacked to dry out of the weather. blocks would theoretically all be 'pre-shrunk' - esp if the mix was consistent from batch to batch.

as the foundation and framing moves along the blocks could move to the walls - where they would still need to be covered from rain - but you'd be able to keep working. you could mortar the blocks together with a lime or clay slip. might be able to pin them to each other and you could tie them to framing with brick ties or similar.
