41 New Street including forecourt railings

41 New Street is a late Georgian house featuring roughcast walls and rusticated quoins on a brick base. It has a hipped slate roof and a roughcast chimney stack. The building stands three storeys high with a basement and has two bays facing Segontium Terrace. The windows on all levels, including the basement, have eared, lugged, and keyed architraves. The middle storey windows have been converted to French doors, while the other windows are renewed small-pane sash windows in their original openings. An added late 19th-century cast iron balcony supported by iron brackets is present on the middle storey. The elevation facing New Street consists of a single bay with windows offset to the right, displaying similar detailing to those on Segontium Terrace. To the left, the doorway features a rusticated round-headed architrave, with a replaced panelled door and the original iron radial-glazed fanlight above it.

The Segontium Terrace elevation retains its original iron railings on a dwarf wall, although the gate leading to the basement steps has been replaced.
