105-109, Oxford Street and 16-18 Hollen Street

This building, located at 105-109 Oxford Street and 16-18 Hollen Street, was constructed as a shop, factory, and offices between 1887 and 1888 by architects Christopher and White for the hatter Henry Heath. It features a beige terracotta facade on the Oxford Street front and has a slate roof, designed in a free Franco-Flemish Renaissance style. The structure is five storeys tall with an attic.

The design exhibits slight asymmetry, with four-window wide wings flanking a two-window wide centerpiece. The ground floor has a mid-20th century shop front, which conceals a bas relief frieze depicting the hat-making process, created by Benjamin Creswick, a protégé of John Ruskin. The upper floors are adorned with mullioned-transomed casement windows arranged in tiers. The left wing has two equal bays separated by plaster strips, while the right wing features three bays with a two-window center. The centerpiece showcases sharply bowed oriel windows on the second floor, with paired arched windows above, decorated with portrait medallions of George IV and Queen Victoria. Above the three narrow arched fourth-floor windows of the centerpiece, there is a scroll-sided gable topped with an incurved pediment. The top tier windows of the wings have arched heads, and a dormered gable is present over the right wing. The gables are finished with decorative finials in the shape of beavers, also modeled by Creswick.

The rear elevation facing Hollen Street presents a more subdued, well-proportioned industrial facade made of stock brick with red brick dressings. This side is four storeys high and six windows wide, featuring a central entrance with a steel lintel. The windows are segmental arched, framed in industrial iron with glazing bars. The top two floors are articulated into three pairs of bays by red pilasters, and there is a stone eaves cornice along with two stone bands between the storeys inscribed with "Henry Heath, Oxford Street" and "Hat Factory."
