Decorating Lonsdale Square
Lonsdale Square is unique among Islington's many Victorian garden squares in having been designed in the Gothic Revival style rather than the Classical idiom that dominates virtually all other residential square developments in the borough. Designed by R.C. Carpenter and developed in the early 1840s, the square presents a remarkable and cohesive ensemble of pointed gables, hood mouldings, and polychrome brickwork that stands in complete contrast to the stucco Italianate of Barnsbury's other squares. This article examines the heritage significance, specialist material considerations, and decorating approaches appropriate to Lonsdale Square's exceptional architecture.
Heritage Context
Lonsdale Square was developed between 1838 and 1845 to designs by R.C. Carpenter, a Gothic Revival architect associated with the Ecclesiological movement and the high-church Anglican circle that was beginning to transform English ecclesiastical architecture in the late 1830s. The choice of Gothic forms for a domestic square was highly unusual and may reflect the influence of the square's principal developer, who shared the religious and architectural enthusiasms of the Cambridge Camden Society. The square is listed at Grade II* as a group, an unusually high designation for a speculative residential development, reflecting its exceptional rarity and the completeness with which the original design has been preserved. It falls within the Barnsbury Conservation Area.
Architectural & Materials Analysis
The terrace houses of Lonsdale Square are built in London stock brick with a distinctive pointed Gothic character: two-storey bays with pointed arch windows, hood mouldings over openings, steep gabled returns, and in some cases polychrome brick banding. The Gothic detailing is executed in rubbed and gauged brick rather than stone, making the Lonsdale Square houses a rare example of brick Gothic domestic architecture at this scale. The lime mortar joints are critical to the structural and aesthetic integrity of the facades; the gauged brick arches and hood mouldings depend on the joint geometry for their structural performance, and inappropriate repointing with Portland cement mortar can cause catastrophic cracking of the moulded brickwork. Original timber sash windows within pointed arch frames survive on many properties.
Specialist Restoration & Painting Implications
The exposed stock brick facades of Lonsdale Square should not be painted or coated with impermeable masonry sealers; the brick's natural patina and colour variation are intrinsic to the Gothic character of the design and any proposal to paint the brickwork requires listed building consent and must demonstrate exceptional justification. Lime mortar repointing must be specified to match the original joint profile — typically a neat struck or slightly recessed joint with a feebly hydraulic lime mortar — and any gauged brick arches or moulded brick details require specialist masons experienced in Gothic brickwork before maintenance intervention. Where stucco or render elements do exist on individual properties, lime-based or silicate mineral paint is required; however the dominant finish on Lonsdale Square is unpainted brick and this should be maintained as the defining character of the streetscape.
Noteworthy Addresses & Cultural History
The square's central garden, enclosed by its original cast iron perimeter railings and planted with mature plane trees, is one of the best-preserved Victorian garden square enclosures in inner north London and remains in private use by square residents. The architectural historian Nikolaus Pevsner noted Lonsdale Square in 'The Buildings of England: London 4' as one of the most surprising and successful residential design experiments of the early Victorian period, his assessment reinforcing its exceptional heritage status. Several of the corner houses on the square retain their original Gothic cast iron lantern standards, among the most complete examples of Victorian decorative street furniture in the Barnsbury area.
