The structure, which accommodates the offices of Llandrindod Wells Town Council, is a Grade II listed building.

[1] The building was commissioned by the first resident medical doctor in the town, William Bowen-Davies, for use as his private house, which he named "Brynarlais".

[2] The house was designed in the Victorian style, built in a combination of yellow brick and rubble masonry and was completed in around 1872.

The extension included a prominent two-storey canted bay which projected forward towards Temple Street and was surmounted by a castellated parapet; there was also an additional porch with columns supporting a modillioned canopy, proving access direct to the surgery.

[1][5] A war memorial designed by Benjamin Lloyd, in the form of a soldier with his head bowed standing on a plinth, which was intended to commemorate the lives of local service personnel who had died in the First World War, was erected in a newly landscaped memorial garden in front of the original entrance to the town hall and unveiled by Lord Lieutenant of Radnorshire, Lord Ormathwaite, in July 1922.
