The building was designed by E. W. M. Corbett,[1] the architect to the Bute estates, and was built of ballast stone with brick facings, resembling a conventional church in the Gothic Revival style, but within, was divided into two floors, with the ground floor housing the Institute, a library and reading room for mariners,[3] the chaplain's room, caretaker's apartments and entrance hall.

In the following decade, the building underwent a £750 renovation, and was reopened by the Viscount Tredegar on 1 May 1906.

The economic fortunes of the area declined in the postwar years, and All Souls closed in 1952.
