7, Alwyne Road

No. 7 Alwyne Road is a detached house built around 1855, likely developed and designed by James Wagstaffe. It incorporates part of a late 16th-century octagonal garden house from Old Canonbury House. The building features yellow brick set in Flemish bond, stucco, and slate roofs, with the brickwork of the former garden house covered in stucco.

The 1850s section has three storeys over a basement and is two bays wide, with the basement displaying stuccoed banded rustication. The ground and first-floor windows are flat-arched with moulded architraves, although the cornices and consoles have been lost. There are balconies and iron railings at the ground-floor windows. The second-floor windows have unmoulded architraves that die into a cornice band. The house has boxed eaves, a side stack, and a hipped roof.

A single-storey porch wing connects the 1850s section to the former garden house. This porch features steps leading up to a flat-arched entrance with Doric pilasters, a cornice, a moulded blocking course, a panelled door, and an overlight. The former garden house is also covered in stucco, with some areas scored to resemble ashlar. It has two windows on the south-west side, including a flat-arched window in the basement under a continuous hoodmould, and a cambered-arched window on the ground floor on this side and the opposite side. An octagonal chimneystack is located on the north-west side, facing Alwyne Place.
