Decorating Nevern Square

Nevern Square was developed in the early 1880s on land that formed part of the extensive landholdings in the Earls Court area. The square takes its name from the River Nevern in Pembrokeshire, reflecting the Welsh connections of the landowning family. The development was conceived as a prestigious residential square, its central garden and unified architectural treatment designed to attract a higher class of resident than the surrounding streets. The houses were built by several speculative builders working to a broadly consistent design brief, producing a harmonious ensemble of Italianate terraces that encircle the central garden. The original residents included prosperous professionals, commercial men, and families with colonial connections who were drawn to the area by its combination of affordable rents, underground railway access, and social respectability. The square developed a notably international character during the late Victorian and Edwardian periods, attracting European emigres, colonial administrators, and the cosmopolitan professional class that characterised the Earls Court area. During the early twentieth century, the square's houses began to be converted to hotels and boarding houses, a trend that accelerated after the Second World War as the area's social status declined. The post-war decades were a difficult period for Nevern Square, with many houses poorly maintained and subdivided into bedsitting rooms. However, the square has benefited significantly from the gentrification of the Earls Court area since the 1990s, with several properties restored to residential use and others operating as high-quality boutique hotels. The conservation area designation protects the square's Victorian character against inappropriate development.

The decoration of Nevern Square requires a coordinated approach that treats each terrace as a unified composition rather than a series of individual houses. The stuccoed lower storeys demand Keim mineral silicate paint in a warm stone tone from the Victorian palette, with particular attention to achieving colour consistency across the multiple houses that form each terrace. The elaborate entrance porches, with their Corinthian columns and full entablatures, require skilled brush application to ensure complete coverage of the complex moulded surfaces, including the fluted column shafts, the acanthus-leaf capitals, and the dentilled cornices. Where the Portland stone or Roman Cement of these elements has deteriorated, repairs should use lime-based mortars matched in colour and texture to the original material, applied in thin layers and tooled to replicate the original surface finish. The canted bay windows require attention at the vulnerable angle junctions where water accumulation promotes efflorescence and paint failure; these areas should be sealed with lime-based mastic rather than modern silicone. The exposed brickwork of the upper floors requires lime-putty repointing where the original mortar has eroded, with careful matching of the mortar colour to avoid the visually disruptive 'ribbon' effect of mis-matched repointing. The mansard attic storeys, being more exposed to weathering than the lower floors, may require more frequent maintenance of their slate coverings and lead flashings. The ironwork, including the elaborate entrance porches and balcony railings, requires comprehensive hand preparation and a multi-coat protective system of zinc-phosphate primer and alkyd gloss finish. The garden railings, being exposed on all sides to weathering, require particular attention to the junctions between the railing standards and the stone coping, where water ingress promotes corrosion.
