However this was actually at Number 1 Addison Road, at the north-eastern boundary of the Holland House estate, and it is probable he was persuaded to buy the freehold from his father in order to attract other high society occupants to the new development.
After his death in 1873 Number 1 Addison Road was mostly demolished and built upon, but part of the house survives as the club-house of Holland Park Tennis Club.
Watts, Henry's wife Sara Monckton Prinsep and her sisters including Julia Margaret Cameron lived, worked and entertained here for 21 years, making it the centre of their salon on Sunday afternoons.
In its place was built a block of flats designed by Austin Blomfield, named Kingfisher House, which continues to occupy the site.
