This is the Crippled Children's home, known as "Bickford House" that was on the Esplanade at Somerton. The dead man was reported found on the beach opposite this house. It no longer exists, but as far as I can ascertain, it was between the parallel streets Ferris St and Bickford Tce. It appears that the crippled children were moved to Regency park in 1976. 

Before it was turned into a children's home, it apparently belonged to the Bickford family. This is the same family known for "Bickford's lime cordial."
