You should not go with wedges that would screw up all other essentials that you probably will have on the exterior (windows).
Ok, if you break down this build into segments you can clearly see that it is in fact two rectangles only touching by one corner with a filler part (blue).
Let's say that the pink square is the straight one the green has to be the tilted one. This calculating may be abit off but the rounded area I've painted is p much 135degreee which makes the tilt of the green square, if you have the pink square as the refer point, 45degree.
If you were to use only bricks to create this angled square you would then use 1x1 in a stair pattern. Basically a square diamond. Then you would just fill in the the blue segment.
I can't assure that this build will ever look good tho. Angled residences is immensely tricky. A commercial building would been something completely else.
Or maybe you should go with wedges.. idk.
