89, Bank Street

89 Bank Street is a building society office, originally built in 1913 as the district office for Prudential Assurance Company. It was likely designed by Paul Waterhouse, who frequently worked for the company. The building is constructed in a Tudor style, with an upper section timber-framed and infilled with plaster, set above a ground floor of Portland stone. The roof is tiled with a brick chimney stack. The building has two storeys and attics, with a symmetrical facade of two windows. The upper floors display close-studding with plastered infill. There are two projecting gables, decorated with carved bargeboards and an elaborate carved bressumer. Each gable features two paired arched windows with leaded lights, including a lozenge pattern below. The first floor incorporates two oriel windows, featuring three mullioned and transomed windows with leaded lights and carved bases. A decorative central rainwaterhead is present, adorned with a quatrefoil motif. Four ogee-shaped stone niches house statues representing Archbishop Courtenay, Caxton, Sir Christopher Marlowe, and Lord Avebury. These are framed by four-centred wooden arches, complete with blank shields and foliate moulding to the spandrels. The ground floor has a stone shopfront with carved stone bosses, pilasters, two oak-framed windows, and two doorcases with rectangular fanlights and arched doorcases. The right-side plank doorcase features a studded door.

The interior ground floor has a square ribbed ceiling with plastered vine motifs. The right-side staircase has moulded balusters and a newel post with panelling below.

The building is notable as a well-preserved example of an insurance office, reflecting an unusual Arts and Crafts style.
