16 St Peter's Square, including churchyard boundary wall to rear

Late-Georgian 3-storey 2-window town-house with rear wing flush with the north gable end, fronting the churchyard. The building is constructed of red brick under a slate roof, hipped to the left end, with a dentilled eaves cornice. There is a central brick ridge stack and a small stack to the right end, probably for a shop.

The front elevation has a central round-arched entrance with a 6-panel door and fanlight with radial glazing bars. The doorcase is ornate woodwork, probably 19th century, with fluted columns on high bases. The capitals are decorated with egg-and-dart mouldings and support scrolled brackets to an open triangular pediment with dentilled decoration. Under the pediment and flanking the fanlight are two small roundels inscribed RR. The house has flush sash windows under flat-arched heads of gauged brickwork. To the right are horned sashes—16-pane to the first floor and 4-over-8-pane to the second floor. To the left are hornless 12-pane sashes to ground and first floor, with a 3-over-6-pane sash to the second floor.

To the right of the ground floor is a later wooden shop-front with a plain cornice. A panelled door with plain overlight (now boarded over) sits to the right between plain pilasters, with a plate-glass bay window on a brick plinth to its left. The rear has a wide 20th-century doorway to the left with a narrow light above and a metal fire-escape staircase. To the right is a shallow full-height gabled bay with openings offset to the left: a wide 2-light casement to the attic and a tall casement to the first floor, both with segmental brick heads, and a small lean-to to the ground floor.

The north end of the house fronting the churchyard is a 2-window range with a hipped roof. The windows are 3-light wooden casements with transoms under segmental brick heads, those to the second floor shorter. Adjoining to the left is a 2-storey rear wing of brick under a slate roof with a brick end stack; the upper storey appears to be later. The ground floor has a 3-light wooden casement to the right and a small infilled opening with segmental head to the left under a segmental brick head. The upper storey has two 3-light wooden casements immediately under the eaves.

Adjoining to the left is a former lofted outbuilding in two parts: rubble stone to the right with no openings, and brick to the left with a small square loft hatch infilled with brick. A churchyard boundary wall of rubble stone adjoins to the left.

The south side of the rear wing is 2-window with large 3-light windows under segmental heads to the upper storey. The ground floor has a 2-light casement to the left and a 20th-century wooden window to the right, between which is a former doorway infilled with brick.

The former outbuilding adjoining to the right was probably a stable. It has two boarded doors, each with a 20th-century casement on its left side and under a long wooden lintel. The loft has a central doorway under a gablet containing doubled half-glazed boarded doors with a wooden hoist above. Flanking the doorway are mid-20th-century wooden casements. The east gable end has a 6-over-9-pane sash to the upper storey and a blocked opening to the ground floor.

To the right is a 2-bay garage, a lean-to off the churchyard boundary wall, with a central brick pier and corrugated lean-to roof. Further right, the churchyard boundary wall turns at right-angles towards the north and contains a former doorway blocked with stone. It turns again towards the east, where it is of coursed masonry with a string course to the parapets, and contains a doorway with a segmental voussoired head, blocked with stone. It then continues in rubble stone, adjoining Christ's Hospital.

The interior of the office contained no features of historic interest; the rest was not examined.
