I am planning to build a balcony approximately 3x6m on the upper floor of my split-level house. I would prefer to avoid a pressure-treated wood deck as it becomes unsightly and requires maintenance. Additionally, I don't want to deal with wood oil near my white plastered facade. Ideally, I would like a concrete construction, but it would be both complicated and expensive. The balcony must stand on pillars about 3m high. Horizontal forces can be absorbed through metal brackets in the wall.
Has anyone tried the following?
Bearing structure in glued laminated timber (cheap at Byggmax).
On top of this, I would lay raw plank 22mm, OSB board about 16mm, and then a waterproof membrane. On top of the membrane, I would place WAB fiber cement board and then outdoor tiles or slate.
Could it be an alternative for others tired of pressure-treated wood? Stiffen the existing deck with more joists, lay down OSB to stiffen and distribute the load, apply a sealant layer to prevent moisture from seeping into the OSB, and on top of this, a fiber cement board to provide a "dead" base for outdoor tiles/cement slabs.
Has anyone tried something similar?
Will it work?
If you find cheap outdoor tiles and fiber cement boards, it need not be particularly expensive.
Comments anyone?

I think you are taking a big risk with moisture and frost damage, but it's not impossible that it will work.
Have you considered composite flooring?

Thanks for the good points.
Maybe it's wise to avoid OSB... I was mostly thinking about getting distance in the Sandwich construction, but maybe the risk of it absorbing moisture is too high. Battens with cc 200? It feels like it's important for the "board" to be rigid. Price and weight are other important factors...
