[6] The red-brick building "combines straight lines with spectacular curved balconies", and has large concrete relief figures of Hebe and Aesculapius by sculptor Gilbert Bayes.

[7] It was re-opened by King George V.[8] The hospital treated over 8,600 servicemen during the Second World War (including fighter pilots Eric Lock and Richard Hillary, who describes it in his book The Last Enemy) and remained independent when the National Health Service was founded in 1948.

[2] From 1977 it began to accept paying non-Mason patients, but financial pressures led to its closure and acquisition in 1992 by the Hammersmith Hospitals NHS Trust, not without controversy.

[3] In 2012 it was stated that the building was being redeveloped by the C & C Alpha Group to house the London International Hospital, which would specialise in cancer and diseases of the heart and brain.

[10][11] In 2015 it was acquired by VPS Healthcare who proposed to reopen it as the 150-bed London International Hospital in 2017, which would be "the centre for tourists to travel to the capital city for state-of-the-art medical care".
