Owners of swimming pools in Surrey and London must love that day when the summer temperature hits that threshold. You know, when it finally gets warm enough to peal back the cover and take the first dive of the year. Or maybe that’s just how I imagine it to be. There’s something aesthetically-pleasing about a large country home surrounded by an immaculately-mowed lawn with a crisp, blue pool shimmering beneath the summer sun. Would it be seen an unprofessional if I ‘accidentally’ fell in one time? Most likely. Anyway, here’s a selection of some of my favourite swimming pools from the properties I’ve photographed this summer.
