Presbytery at Catholic Church of St Peter including forecourt railings

The presbytery, dating to the Gothic style, is a two-storey building with a double-depth plan, constructed of snecked rock-faced stone with lighter freestone dressings and a slate roof topped with coursed stone ridge stacks. It is situated behind cast iron railings that attach to porches on both the St Peters Street and Bedford Street elevations. Most windows feature cusped heads and contain either two-pane sash windows or replaced top-hung casements.

The main entrance is located on the three-window elevation facing St Peter Street. A central porch, constructed of ashlar, has a steeply gabled roof and a trefoiled arch supported by a single marble shaft with stiff-leaf capitals. This arch frames double iron gates with fleur-de-lis finials, leading to a half-lit panelled door with a shouldered lintel and pointed overlight. The door is flanked by tall, cusped windows with iron bars. The sides of the porch feature three open cusped arches. A single-light window is located to the left of the entrance, and above the porch, a three-light window and a single light window to the left extend beyond the eaves beneath gablets. To the right of the entrance is the gable end of the Bedford Street front, which has a canted bay window under a hipped roof, topped by a two-light window with a relieving arch.

The four-window west (side) wall, facing the church, has two half-hipped roof sections. The lower storey features V-shaped windows in ashlar surrounds with shouldered lintels, with pairs of windows above. Further north, the cloister and sacristy of the church attach at right angles.

The east front, facing Bedford Street, has four pairs of windows. To the right of these is a three-light window and a steeply gabled porch, featuring a shouldered lintel to the doorway with a pointed overlight and side windows. A replaced door within the porch also has a pointed overlight. The upper storey has two pairs of windows under gablets to the centre and left, and a three-light window under a half-hipped roof to the right.

A lower projection at the north end connects with the Bedford Street elevation and has a single end stack. It features three-light and two-light windows under shouldered lintels, and a pair of cusped lights at the upper left under a half-hipped roof. The north gable end of this projection includes a boarded door in the lower storey, a window with a shouldered lintel on the left, and a plain window above. Its west side wall has two lintelled windows in the lower storey and a cusped half-dormer above.

The interior is planned around a long, central corridor extending from the main entrance, which provides direct access to the sacristy and church.
