Perfect symmetry

As with yesterday, I'm uploading this a month after the event, and I've no recollection whatsoever of what I was actually up to today.

I recognise the house as being on the seafront road down beside the Martello tower swimming place at Seapoint, but I've no notion what I was doing around that neck of the woods on a Friday. I've long admired this house, and I think it's come out of the camera before as well. Its frontage isn't quite as symmetrical as it appears here (a touch of artistic licence has intervened).
