These buildings on Courtfield Road in Kensington, now very nice looking flats, were built by J.R. and W.H. Roberts in May 1880 and designed by Walter Graves. The section pictured would have been the “lesser rooms” with the nicest section facing the gardens at the back (which I didn’t think to investigate at the time). You can find the original floor plans and more details here.
The fountain below is set in the wall on Marloes Road, near where St Mary Abbots Hospital used to stand. The hospital had originally been two workhouses, then an infirmary that became known as St Mary Abbot’s Hospital in 1923. The hospital was bombed during the Second World War in 1940 and again in 1944 which forced it to close for several years. The hospital finally closed for good in 1992.
