This has probably been posted a million times, lots of people saying must be something wrong with guttering/roof but it’s a new build and there’s nothing leaking. Rain water is running down the render and dripping from the top off the window on to the sill. It’s loud and waking up my 1 year old, it’s clearly a terrible design for the house but is there anything I can do that won’t be an eye sore to prevent this from happening/reducing the sound of the water drops? This is happening on every window where the render is getting wet.

Dan,
Over the head of every window or door opening on a rendered wall there should be a plastic Bell Cast to throw the rainwater off.
Bell Cast's can be retro fitted - and they often are.
Do you have an eaves with projecting soffit's like your neighbour?
Go out when its raining and check that no roof water is running behind the fascia or coming through the soffit.
 
Temporary solution 2 or 3 layer off kitchen roll on the window sill to reduce noise whilst solution implemented
you can probably reduce the paper over several weeks to acclimatize little un to the noise ??
 
Thick piece of white metal. White tiles. Painted slates etc

Or get another length of plastic cill and fill it with cement mortar and place it on top

You won't stop it, neither will a bellcast or storm guard. The cill is very wide and flat as the frame is set too far back and wind blown rain and drips will defeat any thing on the head of the opening.

Best thing to do is get a thin white foam strip/mat and cut it to size for the top of the cill. It needs to be closed cell foam and UV stable. These are normally sold for packing and protection, have a look on Google.
 
Or just live with it like everyone else does. Poor design, what would a bell cast do anyway? Madness.

FMT seemed in a bit of a despairing mood last night; several threads where they deemed the problem too inane to be credible calls for help were subject to a withering comment
