It's easier to carve sandstone to perfect joints than to try and liquify all that (and then let it dry back out.)
Don't forget, the plant extract your talking about would require collection and concentration. That's quite a bit of time and energy.
Also, if such a thing was possible on large scales, why don't we see huts that appear to be carved out of solid sandstone?
Lastly, information about this extract was linked here at ATS not too long ago. Reading it, it appears to me that the extract would dissolve the
materials that cement the sand grains together into stone. How could these be re-cemented back into sandstone that has the same appearance as the
Much easier to simply carve it to fit.
