Conservatory with exposed bedrock

[AnBjaBoo]

I have googled, searched, and thought and can't find a good solution for diverting water or "sealing" so that the water doesn't run in through the intended wall.

How would you build a sunroom where a corner is on a rock as shown in the picture?

I'm thinking there should be windows there and "planks" under the windows - but how do I build considering the water that will run down the rock?!

Track channel with stone saw in front ?

It went so-so to get an answer, but now I'm darn well going to build my sunroom...

Scoring in the rock is great, but how do I build it so the water flows towards it, so to speak...

Any idea if I should drill rebar, leca, fill underneath with expansion stuff?
Or rebar, build a frame, cast with cement/concrete with waterproofing stuff and possibly fill in gaps with expansion stuff?

or some other way? Living in hope of higher knowledge

I didn't get much response, but now, darn it, I'm going to build my conservatory..

Scoring into the rock is great, but how do I build it so the water runs properly, so to speak..

Any ideas if I should drill rebar, leca, fill underneath with expansion stuff?
Or rebar, build a frame, cast with cement/concrete with waterproof jox and possibly fill in gaps with expansion jox?

or some other way? Living in hope for higher knowledge

Score the rock externally so you can divert the water, drill and dowel, form, cast with coarse concrete. You don't need any "jox" and if you want the rock visible inside the unheated conservatory, you don't need to blast.

Trace the mountain outside so you can divert the water, drill and dowel, shape, cast with rough concrete. You don't need any "jox" and if you're going to have the mountain visible inside the unheated sunroom, you don't need to blast.

Thanks! And then you mean that I draw a form on formply, cut, seal, and cast (after dowel)? Tried to find tips on how to draw (have seen comparison against uneven wall with block and pencil but this is rugged and sloping rock..)

Thanks! And then you're thinking that I draw the shape on plywood, cut it out, seal it, and cast (after anchor)? Tried to find tips on how to trace (have seen comparisons against uneven walls with a block and pencil, but this is rough and sloping rock..)

Plywood seems unnecessarily difficult and expensive for that small rock ledge, if you don't have any boards lying around, you can advantageously use 20mm raw board as a form.

FYI - this is how I solved this problem that has been puzzling me: built a framework with "steps" because I didn't want a high wall and the only purpose is to divert water. Will it work? Hope so!

And this is how it drizzles in when it rains. It's okay, nothing gets damaged (gap at the wood) - but - we have sealed with foam sealant, is there any super foam sealant or something else we can try?
