The three-storey townhouse on Yau Sau Street in Happy Valley is a pre-war building rated Grade III by Hong Kong's Antiquities and Monuments Office for its Art Deco style. Lawyer Douglas So bought the whole property for HK$90 million and spent a further HK$15 million converting it into a museum, which opened in September 2014.

The museum opened in September 2014 with an exhibition by Elliott Erwitt. Its second floor holds Douglas So's private Leica collection, while the ground floor and first floor host temporary photography shows. The building's name refers to the f/11 aperture setting.

The museum opened in September 2014 at 11 Yik Yam Street in Happy Valley, on the ground floor and first floor of a three-storey pre-war townhouse; the second floor holds the Leica camera collection. The building is a Grade III historic building, so look for the octagonal windows, radiating sunburst lines and geometric patterned facade.

The building retains a rear service staircase known as the "maid's stair", once used by amahs, the live-in domestic workers of pre-war Hong Kong households. Look for it behind the main circulation of this 1930s Art Deco townhouse on Yau Yat Street in Happy Valley.
