Numbers 23 and 24 and Attached Walls and Gate Piers

Numbers 23 and 24 are a semi-detached pair of houses, with No. 23 currently serving as offices. They were built in the mid-19th century and feature painted roughcast walls with painted stone dressings and a slate roof, which has stacks on the left gable end and party walls. The architectural style is Picturesque Tudor Gothic, and the layout is a symmetrical T-plan, with each house having an L-plan and a rear wing.

The exterior consists of two storeys and attics, with a symmetrical four-window arrangement. The central bays project, creating a 1:2:1 fenestration pattern. The corners are accentuated with rusticated quoins. There are four forward-facing gables with coped tops, moulded kneelers, and stepped eaves bands. The central gables, which are stepped forward, feature a single-light attic window on the left and a 2/2-pane sash on the right. The first-floor windows below are 2/2-pane sashes set in canted bays with hipped roofs. The left bay has an oriel above a three-light timber mullioned and transomed ground-floor window, while the right bay has a rectangular castellated bay with an oriel above. The outer bays are set back and have slightly projecting gables that flank the entrances.

No. 24 has a two-light cross window on the first floor above stepped weathering and a shallow pointed-arched hoodmould with head stops and an overlight above a 20th-century door. No. 23 is similar, but the weathering and hoodmould have been removed. The interior has not been inspected.

There are also subsidiary features, including a shared rubblestone party garden wall approximately 3 meters high that extends for about 20 meters to the rear, and around 80 meters of rubblestone wall of varying heights that flanks and fronts the gardens. Both houses have octagonal Plymouth stone gate piers with flat tops. This development is part of Courtenay Park, which was laid out in 1854.
