Walking around Edinburgh, it was no surprise as to where JK Rowling got her inspirations from!
This building is on the walk from the city centre to Murrayfield rugby stadium.
There's no obvious signs as to what it is, but from checking in Google Earth, I found it was Donaldsons School for the Deaf.
So, on to Wikipedia:
Donaldson's School, in Linlithgow is Scotland's national residential and day school, providing education, therapy and care for pupils who are deaf or who have severe speech and language difficulties.
Donaldson's was founded in Edinburgh in 1851 as Donaldson's Hospital by Sir James Donaldson (1751–1830). The original benefaction allowed for special bursaries for poor children. Not all were deaf, although applications on behalf of deaf children were encouraged. From 1938, pupils were exclusively deaf. This benefaction was similar in style to the benefaction of George Watson, who founded and supported other schools in Edinburgh.
Queen Victoria is said to have been jealous of the landmark William Henry Playfair building in Edinburgh, apparently stating that it outclassed some of her palaces.
During a German air raid in 1916, much glass was destroyed by a zeppelin.
After more than 150 years based in the Playfair building, Donaldson's finally concluded that the building was no longer fit for purpose. Many of the rooms were no longer in use, classrooms were unable to utilise the latest educational technology and the Trust could no longer afford to maintain the building.
Therefore in 2003 the school's building was put up for sale and was purchased by Scottish property developer Cala Homes.
