No 21 and Attached Boundary Wall

No. 21 is a house built around 1820, with later additions and alterations, located in Britannia Square, Worcester. The building features painted stucco over brick and has a hipped slate roof with partially renewed end stacks that have brick oversailing detail and pots. The house has an L-shaped plan with a central entrance and is two storeys high, with three first-floor windows. Architectural details include pilaster strips at the ends, a shallow break-forward at the center bay, a fluted door surround, and a plain eaves band. The windows are 8/8 sashes, except for the first-floor center window, which is a 6/6 sash, all set in plain reveals with sills. The entrance door is a six-panel design with a fanlight featuring a circular glazing pattern. The rear of the house retains 6/6 sashes.

The attached boundary wall is approximately 30 meters long and 2.5 meters high, made of brick and located to the south of the house. It includes a pedestrian opening with a segmental arch and a vertically boarded timber door.

All the listed buildings in Britannia Square form a cohesive group, initiated in 1820 and arranged around a large green, with the main house known as 'Springfield.' This development is comparable to other similar, though smaller, projects in Worcester, such as Lansdowne Crescent, Lark Hill, and Rainbow Hill Terrace.
