Finished drawings for Holy Trinity Church, Marylebone, London, without a tower, November 1820 (2)
These two designs do not fit comfortably within the late 1820 schemes. The two designs seem to be slight variations of each other. This may indicate Soane was hypothesising a potential church without a tower. Such a church would have saved on expense, but would have had little precedence in Britain, especially in the classical style. Some churches such as Thomas Rickman's St Paul's in Preston (1823-1825) and Francis Goodwin's Holy Trinity in Birmingham (1820-1822) had high pediments and tall buttresses flanking the entrance and rear, instead of towers, but these were Gothic in style.
Carr suggested French Church architecture may have influenced this idea, for example Saint-Philippe-du-Roule in Paris by Jean François Thérèse Chalgrin from 1774-84. Soane visited Paris in 1824 and 1819, but it is unknown whether he visited this church; but as Carr noted he had engravings of it in his collection to consult.
