Numbers 67 to 73 (Consecutive) and Attached Railings

Numbers 67 to 73 are a terrace of seven houses located on the west side of Myddelton Square, built between 1824 and 1827 by William Chadwell Mylne, who was the Surveyor to the New River Estate. The houses are constructed from yellow stock brick in Flemish bond, featuring a banded stucco ground floor and stucco dressings. The roofs are covered with artificial slate, while others are obscured by parapets, and there are brick party-wall stacks.

The terrace has a side-hall entrance plan and stands four storeys high with a basement, with two windows for each house. The right-hand return wall of number 67 has a two-window range facing Inglebert Street, and the left-hand return wall of number 73 has a two-window range facing River Street. The facade is symmetrical, with the end houses slightly projecting.

Steps lead up to a round or elliptical-arched entrance on the left, which features a stucco portico side entrance to number 67, with an architraved doorway flanked by three-quarter fluted column jambs and panelled pilaster jambs. This doorway is topped with a corniced head, a patterned fanlight, and the original panelled door. The ground floor has round and elliptical-arched architraved sash windows, with margin lights and coloured glass in number 70, along with a panel below each window. The upper floors mostly feature gauged brick flat-arched sashes, with a mix of 6/6 and 3/3 panes.

On the first floor, there is a stucco sill band beneath full-length sashes set in arched recesses, which are linked by stucco impost bands. These windows are adorned with iron-bracketed coupled cast-iron balconies that have bamboo and anthemion patterns in their railings. Numbers 71 to 73 have undergone extensive rebuilding on the upper floors, and they feature a plain brick parapet with a brick string course and stone coping. The terrace is complemented by good cast-iron railings that have urn and acorn finials.

Myddelton Square is noted as the largest square in the area aside from Finsbury Square and is regarded by some as Islington's best and most significant feature of the New River Estate, being the most stylistically cohesive in the district.
