More specifically it was Number 6 Gloucester Gate, the blue plaque of which is visible just above the yellow car. This was owned by Henry Wellcome (Wellcome Trust etc) who seemed to like pampering cats. So much that they were evidently the only residents of this palatial address because he actually lived in a Portland Place hotel leaving strict feeding instructions for the cats in Number 6. Gloucester Gate.
