1-6, Avenham Colonnade

A terrace of six town houses at 1-6, Avenham Colonnade, built around 1830 and altered in the later 19th century. The houses are constructed of red brick in a Flemish bond pattern, with sandstone dressings and a slate roof. Each house has a double-depth, split-level plan arranged single-fronted.

The architectural style is characterized by a sandstone plinth, a broad sill band to the first floor, a plain frieze, a prominent moulded cornice with a blocking course, and two storeys over basements (with a three-storey rear to some houses). Each house has two bays. The doorways, located to the right of each house, are round-headed, set within broad banded sandstone architraves that feature cornices at the level of the first floor band. The panelled jambs have impost mouldings, and the doors are set progressively lower, accommodating the sloping ground from houses 1 to 6. The fanlights above the doors lengthen from semicircular to stilted designs, all without glazing bars. Basement and ground floor windows are segmental-headed with moulded architraves; first-floor windows have wedge lintels. Most windows are sashed without glazing bars, though No. 2 has top-hung casements imitating sashes. Chimneys are positioned on the front slope of the roof. Skylights are present at houses 2, 3, and 6, with small dormers at houses 4 and 5.

The rear elevations show added canted bays to houses 2, 5, and 6 (No. 2 being three-storeyed, while the others are two-storeyed). The rear wall of house 4 was recently rebuilt. Most rear windows have altered glazing, except for a surviving 20-pane sash window at the basement level of house 3.

The interior of the houses features an unusual split-level design, incorporating stone steps leading to a raised rear ground floor level and down to the basement. Historically, the front ground floor was protected by a continuous colonnade with a flat roof.
