Bert and Ada and another torn photo from Seaforth

I have previously posted a picture of Jack, Celia and Peter at Seaforth. It had been torn along one side. Now here we have Bert and Ada at the same address, but this time the photo has been torn horizontally and the bottom half is missing. I imagine Seaforth is a holiday cottage somewhere as I have no other record of this address, but I do not know where.

Jack, Celia and Peter "Seaforth"

This must have been taken in the late 1940s. Notice the tear down the right side. I haven't found the other half of the picture.
