Usually building the roof higher gets rid of those gaps.
The forest roof holes.
You build a custom roof and it looks like its floating in the middle with massive holes at either end glad to natives dont throw grenades at you or they could just throw it though the holes.
Alternatively you could slap a floor down and then run a wall on top of the floor down the middle to fill it and then use vertical logs on the outside to cover that up.
Keep in mind if you computer struggles to run the forest cutting more holes in these buildings will causes your game to run slower.

The hole cutter has a max cut limit of 20 holes for custom roofs custom floors and custom foundations.
After this limit is reached you will no longer be able to cut holes even if you haven t finished.
