TL;DR

Make it possible to create non-rectangular buildings.

What?

Some buildings are not rectangular in shape, and when they are large enough, they leave empty space at the corners of the bounding rectangle, which can look incongruous if other objects adjoin the building in that location.
For example, inserters moving objects into the “empty” space.

Look at this lab (from Paranoidal)


For example, you can make it possible to set the end points of buildings not by the corners of the rectangle, as it is now, but by a list of coordinates of the corners of the polygon.

Why?

This would look more natural, and also give more opportunities to diversify the graphics of objects.

Isn't the fact that buildings can only be rectangular done at the game engine level?
Is that something that can be changed with mods?

No. Factorio is specifically optimized to work with rectangular objects on an orthogonal grid. Support for non-rectangular objects will not be happening due to the sheer number of edge cases.

If you want it to look more natural, the graphics should be adjusted to not have empty space.
