Decorating Barkston Gardens

Barkston Gardens was laid out in the 1870s as part of the Gunter Estate development, one of the principal landowning interests in the Earls Court and West Brompton area. The Gunter family, who had amassed their fortune through confectionery and property speculation, employed the architect Walter Graves to design a series of harmonious terraced crescents that would attract prosperous middle-class tenants drawn to the area by the newly opened Metropolitan District Railway station. The crescent's name commemorates Barkston, a village in Lincolnshire associated with the Gunter family. The houses were designed in the Italianate manner then dominant in London's western suburbs, with stuccoed facades, bracketed cornices, and pilastered entrance porches intended to evoke the palazzi of Renaissance Italy. The street's communal garden, enclosed by cast iron railings, was planted in the mid-Victorian Gardenesque tradition with specimen shrubs and perennial borders. During the twentieth century, many houses were converted to hotels and multi-occupancy flats, a process that often entailed the application of modern masonry paints and cement renders over the original lime substrates. The designation of the Earls Court Conservation Area and the enforcement of Article 4 directions have since provided the regulatory framework for systematic restoration, encouraging property owners to reinstate original materials and decorative schemes under professional conservation guidance.

The conservation redecoration of Barkston Gardens properties demands a thorough understanding of lime chemistry and the compatibility requirements of heritage substrates. Before any coating application, the existing paint system must be carefully surveyed: modern acrylic masonry paints, which are vapour-impermeable, must be removed to restore the breathability of the underlying lime stucco. Removal should employ either controlled steam stripping or a proprietary alkaline paint remover specifically formulated for use on calcareous surfaces, avoiding acidic products that would attack the lime binder. Once stripped, areas of defective stucco should be repaired using a like-for-like lime mortar, mixed from mature lime putty aged a minimum of twelve months and a sharp sand aggregate colour-matched to the original. Roman cement ornamental details may be repaired using a proprietary NHL-based repair mortar pigmented with mineral earth colours to blend with the adjacent weathered surfaces. The finish coat specification should be a potassium silicate paint such as Keim Purkristalat, which forms an irreversible chemical bond with the lime substrate through the process of silicification, yielding a coating of extraordinary durability and vapour permeability. Colour selection should reference the original Victorian palette, typically a Portland stone buff or a warm cream, verified through micro-sample analysis of protected areas such as beneath cornices. Timber sash windows require stripping to bare wood using infrared heat methods, treatment of any decayed timber with a consolidant resin, priming with an aluminium wood primer, and finishing with two coats of flexible alkyd gloss. Cast iron balconettes should be prepared to Sa 2 standard, primed with zinc phosphate, and finished in a traditional gloss, typically in black or dark green as specified by the conservation area guidelines.
