How to seal a door to stop rain getting in?

[Astrokev]

My obsy will have an externally opening door, with a standard sloping cill.

There are several commercially available solutions to stop rain getting in but I'm curious what obsy builders have found the simplest and most effective?  My main concern is at the bottom, underneath the door.

Thanks ?

If you mean the door opens outwards, then make the frame deep enough that with the door in the closed position you can put "stops" around all four edges. They are just strips of wood that sit on the frame at the back edge of the door closing the gap between the door and the frame. Of course you can put the stops on the outside if the door opens inwards. You won't end up with a flat sill a the bottom of course, but it does make an effective barrier to rain. My sill doesn't slope enough and water will pond on top, but it doesn't make it inside.  See 3rd photo here:

If you have the space, put a canopy over the door frame to direct rain away....

As you say lots of fancy designs out there but we just used a strip of 6mm galvanized weather bar set in a groove in the sill and a step cut in the bottom of the door, there was also a plastic strip available to cover the top edge,

Something like this roughly

Thanks Ian. Looks simple and effective ?

I would put trim round the left, top and right hand sides of the door. The same as you have on your internal doors in your house and then use one of those door weather bars at the bottom. Like these:
