Custom House

The Custom House in Great Yarmouth is a house built in 1720 for John Andrews, a prominent herring merchant. In 1802, it was purchased by H.M. Government for use as a Custom's House and was sold in 1986 to the Port of Yarmouth Commissioners. The building is constructed of red brick laid in Flemish bond, with stone quoins and dressings, and features a slate roof. It has a single-pile plan and stands three storeys tall on a basement, with a total of eight windows across its facade.

The central double doors span two window bays and are framed by an early 19th-century porch supported by a pair of Greek Doric columns. The basement and all other windows are set under segmental stone arches with keystones. The ground and first floors have horned sash windows with 9/9 glazing bars, while the second floor features horned sashes with 6/6 glazing. A parapet partly conceals the shallow-pitched gabled roof, which has a pair of stacks on the rear wall. Flanking the facade are narrow bays that lead to arched entrances for Row 103 to the north and Row 104 to the south, with a 9/9 sash window above each entrance.

At the rear, there is a two-storey outshut and a two-storey gabled extension. Inside, the entrance hall features large-framed panelling on the north side, and there is an open-string staircase with three balusters per tread, including a turned baluster, an iron-twist baluster, and a barleysugar baluster. The staircase has carved floral tread-ends and a moulded ramped and wreathed handrail. The main room on the ground floor to the north has a bolection-moulded fireplace and is surrounded by large-framed panelling. The corresponding room to the south features an 18th-century rosette and dart surround to a 20th-century tiled fireplace, along with large-framed panelling and a moulded cornice. The north attic room contains re-used 17th-century small-framed panelling, while the 19th-century roof consists of common rafters, a purlin, and collars.
