Description
Dagmar House, formerly known as The Old Rodney's Head Public House, is a former public house that has been converted into offices. It was built in 1876, designed by Rowland Plumbe for George Day, and underwent alterations and refurbishment around 1989.
The building is constructed of red brick laid in English bond, with dressings that are presumably stone but have been painted. The roofs are obscured by a parapet. It stands five storeys tall and features a five-window range. The ground floor has an arcade of five pointed arches, with high chamfered stone bases and short columns that have patterned naturalistic capitals, acting as responds in the outer bays. The arches are likely made of brick but are now plastered over. The ground floor also includes a fascia, a coved enriched cornice, and fascia stops.
On the first floor, the windows are topped with flat shouldered arches that have decorative patterns on the impost blocks and lintels. There is a sill band on the second floor that features anthemion ornament on the coved cornice. The second floor has two outer pairs of windows with segmental shouldered arches and patterned impost blocks, with the pairs grouped under a segmental patterned hoodmould.
The central recess on the second and third floors has been plastered over, simplifying the details. There is a sill band on the third floor with pairs of pointed-arched windows in double hoodmoulds flanking the central recess. The central feature is a bust of Rodney resting on a corbelled column, which is supported by an elaborate corbel table, frieze, and patterned cornice on either side. Above this is a central gable with a pointed arch behind the bust of Rodney. The building has a balustraded parapet on either side, with finials at both ends, and dormers located behind the parapet.
