Numbers 5 to 11, 11a to D (Consecutive) and Attached Railings

Numbers 5 to 11, and 11A to D, are a terrace of eight houses located on the south side of Myddelton Square, Islington. They were built between 1824 and 1827 by William Chadwell Mylne, the surveyor for the New River Estate. The houses are constructed of yellow brick in a Flemish bond pattern, with banded stucco to the ground floor (which is rusticated on numbers 11A to D) and stucco dressings. The roofs are artificial slate, though those of numbers 11A to D have a mansard form, while the others are obscured by parapets. Brick stacks rise from a party wall.

The houses follow a side-hall entrance plan. Number 5 has been altered, with the former entrance now a sash window, and it is combined with number 6 to form a single entrance now numbered 5/6. Steps lead to a round or elliptical-arched entrance to the left, featuring fluted column jambs (pilasters on numbers 11A to D), a corniced head, a fanlight (with patterned glazing on numbers 7 and 10), and a panelled door for numbers 5/6 and 11A to D. The ground-floor windows are round-arched and elliptical-arched sashes, except for numbers 11A to D which have square-headed sashes set in recessed panels. Upper floors have gauged brick flat arches, mainly with 6/6 and 3/3 sashes, some of which are French doors. A stucco sill band runs along the first floor, beneath full-length sashes set in arched recesses (except for 11A to D), linked by stucco impost bands. Iron-bracketed balconies with cast iron railings featuring Vitruvian scroll and anthemion patterns (floral patterns on numbers 11A to D) are present on the first floor. Plain brick parapets with stone coping run along the top of the building, with a stucco band on numbers 11A to D. Well-preserved cast-iron railings with urn finials are attached to the front.

A one-storey stucco portico entrance, mirroring that of numbers 12A to G on the opposite side of the square, extends from the left-hand return wall of numbers 11A to D, reflecting a passage cut through to the back gardens. A 20th-century wall along the Myddelton Passage elevation (for numbers 5/6) was erected following bomb damage and the demolition of numbers 3 and 4 during the Second World War. The terrace represents a significant architectural feature of the New River Estate, regarded by some as Islington's finest and most cohesive example.
