[95] Design for the timbers of Holy Trinity Church, Marylebone, London, 13 January 1826

Plan of the arrangement of timbers for the gallery floor. The slats include a couple of thicker beams inserted into the side wall and arranged horizontally, and there are further slats arranged vertically. The horizontal beams are attached by metal clamps to a thicker girder running vertically on the right-hand side. On the right-hand side is a section for the arrangement of the truss to support the gallery floor, with a thick beam at the bottom, with braces attached to it with iron rods, and the King post rising vertically from the centre to meet the braces. The beam at the bottom, and a half beam attached to the King post are connected to the masonry by plates Above is an axial half-section of the eastern end of a church. The left has an external engaged Ionic column in profile. The aisles are divided at nave and gallery level by a landing with the risers for the pews, with doors at each end, and an arch extends over the aisle roof. A large arch with a spandrel spans the nave which shows floor timbers and at gallery level are two arch-topped windows. The shallow roof over the aisles and higher pitched roof of the nave show the timber arrangements: trusses and joists and connecting metal rods
