I'm considering building a small pavilion, round with a pointed roof and about 10sqm. I'd preferably like to avoid gutters, since the roof will be circular, and additionally, it wouldn't look good. So, some rainwater will splash up on the lower part of the facade. The question is, which material can best withstand this? I'm primarily considering using vertical pressure-treated wood paneling, with plastic behind, of course. Then it would be easy to replace when the time comes. But I'm also thinking about building with brick. How would that hold up against splattering roof drips? The mortar might suffer, but it can be filled in eventually. Or are there even better alternatives?
Isn't there a risk of a lot of dirt splashing up on the facade without gutters? It can be difficult to achieve something that looks right with a round roof. The question then is whether you can fill near the gazebo with something that dampens the splashing.
Wood chips work well for filling if you want to avoid splashing.
Sure, I expect dirt, but it's just a matter of rinsing it off with the pressure washer. But what handles the water splashes best? Will the brick suffer, for example, absorb water and then freeze and crack? Pressure-treated paneling will probably last at least ten years before it becomes too rotten, and it's easier to replace than brick. But if the brick withstands for several decades, maybe it is still preferable...
Gravel works well to reduce splashing. What's wrong with regular wood? As long as it dries out and isn't in water/moisture (i.e., in the ground), it lasts a long time. Just look around at older simple houses, like fishing shacks, sheds, etc. They easily stand for 100 years.
I myself have a type of grill cabin/gazebo that is hexagonal and it has been around since 1904, and there is no sign of rot.
But if you make all the general mistakes like putting the wood against the ground and then painting with plastic paint, large parts will be completely rotted through within a few years.

If you accept that it splashes a little occasionally, build in wood. However, skip the pressure washer when cleaning. I believe you accelerate the problems with rot in such cases. Just like when washing a house facade, it's not suitable to use a pressure washer. You push moisture into the wood with such a device. A small plinth foundation so you rise above the ground doesn't hurt either.
Considering a sheet metal roof laid in the form of scales. My brother is a roofer and is passionate about these roofs that you sometimes see on, for example, churches. I think it would suit a gazebo in an old style. I was thinking of letting the roof extend as far as possible without ruining the proportions, so the walls are a bit better protected, and of course, let the foundation rise a bit above the ground. But I was thinking of pouring a slab, it will be placed on a rock slab. Not ideal in terms of splash aspect, even though there is a decimeter of soil to work with. Then the location is sheltered by oak branches, and that helps a bit during the green season at least.

Lucky you to have a brother who is a plåtis. Can't he make a small metal gutter and as ppalm writes "with drops on two sides"
