Well one cannot be said that you are not trying to push the envelope mate.
I wish you the best of British old mate!
Very novel idea and maybe you will discover how the pyramids were built.
The highest that I have gone is 4.5 metres load bearing using 8' x 3' x
3' bales. I also consulted for a load bearing building using 8'x4'x4'
which went 4 high or 4.8 high.
How about building it the way the Yemenis did with their 7 story high
mud brick buildings? i.e. building a very wide foundation and gradually
declining the size as you rise?
Ground floor; Maybe 8'x4'x'4' on their flat and then faced inwards so
you get an 8' wide wall as the base, go 18' high or 6.0m. 5 bales.
Second floor could be 8'x4'x4' with the bales on the other plane i.e.
4' wide. This gives you a 4' wide base to sit the floor joists on.
4 high i.e. 4.8 metres high. 14'.
Third floor could be 8'x3'x2'bales with the 2' wide i.e the bales on
edge. This gives a 2'wide base for the floor joists. 3 high i.e. 2.7
high or 9'.
Fourth floor standard bales. This gives a 6'wide base for the floor
joists. 6 high or 8' or 2.4m
A total height including bottom, middle and top plates of some 16 metres
high or 50'. Aprox. Bloody high mate. Do not know if it would work
though but just another way to look at it.
All floors load bearing. You will need scaffold for this method.
I have a heap of problems with the idea though, but the main concern
would be moisture protection. With good rendering details you may just
succeed. You will need good water proof capping for the top of the
walls. Earth based lime putty finished renders may just be water proof
but they do crack under load and once you have a crack you have a
Anyhow have fun. Hope it helps the thinking.
