Designs and finished drawings for the exterior of Holy Trinity Church, Marylebone, London, 1822 (14)
The 1822 designs were Soane's second attempt to come up with a feasible design for the Church. A five-by-nine bay arrangement is still the preferred option. The tower differs in many respects. Soane was making the first tier with free-standing columns supported by their own individual architrave. This broadens the lower tier of the tower. The second tier is formed on most of these drawings by a series of segmental pediments (on SM 54/3/3 this is absent). At this point, Soane seemed to have experimented with having either three small windows within, or one large, sometimes latticed. This does not seem to have been clarified at this stage, and can still be said to be experimental. Furthermore, some of the metopes start to be shaded (SM 54/1/30-32, 34-5; SM54/3/2). Carr suggests that these were further windows to allow slightly more light by foregoing the gallery lights of the 1820 scheme for 'mezzanine' level lighting instead.
A key feature of many of these drawings for both the exterior and interior is the splitting of the Church between alternate designs. As they are to scale, it should be assumed Soane had either a shorter or taller tower alternative in mind, the attic roof is higher on some split-designs too. Externally, Soane seems to have decided on non-transomed bay windows on all the side and end bays, meaning large round-headed windows would serve the purpose along with small clerestory windows to light the interior spaces. Columns along the side are limited to pairs articulating the first and eighth bays, and the fluted Doric order is maintained.
