Hello,
I'm planning to build a new staircase to the front door. I'm thinking of building it from solid granite blocks weighing about 230kg each. (See the first image for design. The visible blocks on the side are regular "normal blocks," tumbled. The second image shows which blocks are granite).
I know that it's normally filled with crushed rock under this type of stone block, but since this is next to the facade on both the left and back sides, I don't want any pressure to be created against the facade in any way.
Shouldn't it therefore be possible to build up with lecablock underneath, say in three "walls." (Third image).
When I calculate this according to the lecablock specifications, they are rated for 3Mpa, which means they can handle 34 tons per block if the entire block is loaded evenly. That sounds like quite a bit of margin for a staircase that will weigh about 2 tons in total.
However, I can't find anyone who has done this before. Everything seems to be done with stone underneath, or built on an existing slope.
Am I completely off base with this design, or am I right in thinking that this should work without any problem?
Grateful for answers!

thread lift: how has it gone with this. I am looking into something similar.
Ended up with a completely different design, a variant in wood instead. Strongly believe it would have worked, but unfortunately haven't tested it. Hope you find a good way and good luck!
Thanks, I have a neighbor who follows a similar principle. I will check with him.
