16 High Street

16 High Street is a building dating from around 1585, designed in the Dutch Renaissance style. The front of the building was raised and had its windows changed in the later 18th century, and the original ground floor loggia was infilled. Initially, it was built in the "deux corps de batiments" style, but the separate kitchen block and gallery were demolished in 1968. The building became the Naval Bank in 1902.

It stands three storeys tall and has three windows, topped by a hipped Welsh slate roof. The front is plastered timber-framed and features a modillion eaves cornice. There are decorated plaster friezes with lozenge motifs, the date "1585," and the initials "N.B" on the first floor. The first and second floors have rusticated pilasters on the corners. The original frieze on the second floor was removed when the building was heightened.

The later 18th-century windows on the first and second floors are linked, architraved sash windows with glazing bars. The former ground floor loggia had a three-bay Tuscan colonnade with semi-elliptical arches and enriched spandrels, which was infilled with a mid-19th-century segmental arched sash window. The house doorway features the original doors from 1585, re-hung, with pilasters supporting a semi-elliptical blind arch that repeats the colonnade's motif, along with rusticated panel infill and wrought iron pegs.

Inside, the building has been remodelled but retains a fine plaster ceiling on the first floor, decorated with rib work and floral motifs. The ceiling beam and frieze display rose motifs and roundels inscribed with "M.E." (M. Laithwaite).
