Church Hall, St John's Church, Mid Yell, Yell

St John's Church is a 1832 T-plan church with alterations dating to around 1890. It is situated within a square churchyard, and includes a church hall at the northeast corner. The church's walls are harled, with droved ashlar margins.

The church presents a symmetrical design, with the gabled north jamb projecting centrally. A stone staircase leads to the main entrance, a six-panel, two-leaf timber door, situated in the centre of the north jamb, with a two-pane metal fixed light above. Further four-pane metal fixed lights are present in the sides of the north jamb and the south range. The west gable features a porch with a vertically-boarded timber door and a three-pane metal fixed light. A twelve-pane timber sash and case window is positioned centrally in the gablehead above. The south elevation is also symmetrical, with tapering harled buttresses flanking segmental-arched stained glass windows with timber tracery. The east gable mirrors the west.

The roof is covered in purple-grey slate, with droved sandstone ashlar skew-copes. A bell-cote rises from the north gable, consisting of a harled square plinth, corniced ashlar, and a bird-cage style bellcote.

Inside, the ground floor is lined with vertically-boarded timber wainscoting. A panelled and crenellated screen separates the entrance vestibule from the north jamb. The pews are horizontally-boarded and raked towards a grained mahogany pulpit, centrally positioned on the south wall. A raised platform, enclosed by a balustrade with stop-chamfered stanchions and urn finials, supports the pulpit, which also features a vertically-boarded timber base. A timber stair provides access to the west, accompanied by fluted pilasters and a round-arched panel leading to a corniced octagonal canopy embellished with a ball-finialled ogee dome. Galleries in the east and west jambs are accessed by timber stairs in the southeast and southwest corners. An organ by R Donaldson of Glasgow is situated to the east of the pulpit. Timber traceried windows with leaded and coloured glazing flank the pulpit. The ceiling is timber-boarded, with circular ventilators. Four-panel doors are centrally positioned on the end walls of each aisle.

The church hall, built in 1893, is symmetrical, with a gabled porch and a three-pane fixed light in the north gable, and a four-panel flush-beaded timber door in the south wall. Matching windows are located on the principal gable. A modern single-storey addition has been added to the west elevation, while the south gable is blank. The east wall features a four-pane sash and case window and a four-pane fixed light in the left and right bays respectively. The main roof is purple-grey slate, with asbestos tiles on the porch. Skew-copes are rendered, and a ball finial adorns the north gable, alongside a harled gablehead stack with an octagonal can on the south gable.

The churchyard is enclosed by a drystone wall with a rubble cope.
