I’m planning out some built-ins that will wrap around the walls of a study. I’m attaching an example of one place where two units meet in a corner. The counter top on the right is about 17” and on the left 13”. The part that is bugging me here is how to handle the solid wood tops where they meet in the corner. Should it be a butt joint or miter? If it’s a butt joint does it matter if the wider one extends all the way to the wall or the narrower one?

My thought is to attach the counter top to the base cabinets only with some elongated holes to allow for movement. The top shelves will be attached to the wall and resting on top of the counter top but not attached to it. I just don’t know about the two tops meeting each other.

I would just butt joint them with a biscuit jointer to keep it simple.

If you are worried about movement, just leave them dry. They will still keep the surfaces flush to one another while still allowing movement between the cabinet and the wall.

I’m with Brad. I would use a spline of some kind to keep the tops flush, and attach from underneath with screws & elongated holes

If the narrower one butts into the wider one, there will be that much less movement between the two.
