How to build a 30º corner with bricks

[Plura]

Hello
I'm planning to build a base for a greenhouse using old homogeneous bricks 120x250. Some corners will be at 30 degrees. The bricks will be staggered half a brick on the walls connecting to the 30-degree corners. Both the inside and outside will be visible.

What are the different ways to lay the bricks? Which way looks best from both sides?

Not far from the 30-degree corner, there will be regular 90-degree corners, which will be a visual reference, so I think a continuous seam with mortar (if all layers are made with two 15° cut bricks) will look strange. I have no problem cutting the bricks in any way (could be cuts that change direction). It doesn't matter if a cut surface becomes visible, I've tried it, and there's not too much difference from an uncut one.

If you don't mind the cut surface being visible, it will probably be both easiest and nicest to cut the stones and handle it like this: https://www.wienerberger.co.uk/products/brick/special-bricks/angle-and-cant-bricks/an1.html

Hi

Thanks for the response! If I've calculated correctly, with 120x250 brick, the recess on the inside will be 18.5mm deep.
Any other suggestions without "recesses"?

Hello

Thanks for the reply! If I counted correctly, with 120x250 stone, the groove on the inside will be 18.5mm deep.

Well, you could make a corresponding cutout in the other brick, if you don't have many layers it might be doable.

I think this will look the best, dashed is the layer below

You just happened to draw it wrong here, right? Otherwise, I don't understand why that joint would be anything other than 90 degrees.

I don't know what kind of bricks you are using, but I hope you have a base under the bricks.

Hi, no not wrong. It's to get even distance between the joints on both the inside and outside.

Well, if you want that level of symmetry, you just have to keep the stone saw running...

Yes, my original question was which layout was the nicest. Not the least number of cuts or whether I need a foundation under it 😉. But there are several weeks left until the masonry starts, so if there are more suggestions for even nicer corners, I'd gladly accept them!!
