Coinage House, 2 Princes Street, is a grade II listed building, listed in 1993. It was one of the original buildings protected by the conservation area in 1969. The property was designed by William White, a famous English architect, who was noted for his part in the 19th century Gothic Revival architecture and church restorations, for which he was respected nationally as a pioneer in. His portfolio contained hundreds of churches, parsonages, schools and private houses in the UK and abroad including South Africa and Madagascar.

2 Princes Street was built in 1849 and was originally a Victorian private merchants house, evident with the strong room to the centre of the ground floor plan (now bin and bike storage facilities). There is also evidence of window security shutters to the Green Room, which indicates that the property was owned by someone with wealth.

Many of the original exterior architectural features remain intact and there has been no significant alterations internally. The property has a simple classic Victorian gothic design with medieval and Tudor detailing throughout.
