[1] The building was commissioned by the Parish of St John to replace an existing vestry hall in Walham Green.

[3] In the villa's grounds there had been a mulberry tree, which had been planted by Nell Gwyn or her lover; it was chopped down and made into walking sticks in order to make way for the new vestry hall.

[1] The design involved a symmetrical main frontage with seven bays facing onto Fulham Road; the central section of three bays featured an arched doorway with carved tympanum above flanked by windows; there were three windows each flanked by Ionic order columns on the first floor; there were three ocululi on the second floor and a lucarne with another oculus above.

[8] The building was extended again, this time to the west along Fulham Road, in 1934 to accommodate the local registrar's office.

[9] A large stained glass window, depicting Earconwald, who served as Bishop of London in the 7th century, was designed by Francis Spear and made by Lowndes & Drury; it installed at the head of the stairs leading to the Great Hall in the 1930s.
