Plaster board and plastered window sills?

[Andyoxon]

Hi what are your thoughts on just plastering internal window sills instead of using window boards, the wife doesn’t want an over hang and the gap under a couple of the windows is supper tight so no real room for a window board without cutting out the beading and plaster on the facing wall.

 

looking forward to hearing if this is a good or bad idea

 

cheers

Plasterboard as a window sill will not stand up to much use and will wear, dent and chip very easily.

 

As for no overhang, I achieved that a different way.  I was using up left over engineered oak floor boards for my window sills, and needed something to cover the unfinished edge so just a bit of wood trim, with the actual board flush with the wall

Stone cills/polished marble like are popular in Europe. Even available in some European DIY sheds.

You can plaster them and plant a nice tile with a metal edging strip on the outer edge

Would the sills be in a spot where people would likely put something on them? If they are just painted in mat emulsion and people start to put vases and tea cups there it will stain. If not then I don't see why not plasterboard, we have some plasterboard alcoves which are basically the same idea.

Aren't window sills a "structural" necessity? As in the cover up where the window meets the frame thus hiding any movement and also stop the base of the window moving/being pushed inward.
