Decorating Kent Terrace

Kent Terrace was designed by John Nash and constructed in 1827 as part of the final phase of the Regent's Park development. Named after Edward, Duke of Kent, father of Queen Victoria, the terrace departs from the standard park-terrace formula by presenting its houses as paired semi-detached villas rather than a continuous unified facade. This arrangement reflected Nash's recognition that variety was essential to the park's scenic composition — if every terrace had employed the same palace-facade formula, the cumulative effect would have been monotonous rather than picturesque. Kent Terrace's paired villas, each designed to read as a single substantial house, introduced a more domestic scale that provided a visual counterpoint to the monumental terraces on either side. The original houses were of modest size by Nash terrace standards, each comprising three principal floors over a basement, and attracted professional families and minor gentry who valued the park-facing aspect without requiring the grandeur of Cumberland or Chester Terrace. The terrace's position near the southern edge of the Outer Circle, between Cornwall Terrace and the Marylebone entrance, placed it in proximity to the commercial and professional services of Marylebone High Street, an advantage for its middle-class residents. The twentieth century brought conversion to flats and some institutional use, but the external facades survived substantially intact. The Crown Estate's restoration programme addressed Kent Terrace in the 1990s, with a particular focus on the renewal of the stucco facades and the reinstatement of original window patterns where these had been altered by previous occupants.

The decoration of Kent Terrace's stuccoed facades follows the Crown Estate's standard specification for Nash terraces but with adaptations that reflect the terrace's distinctive villa-pair arrangement. The gaps between the villa pairs create exposed return walls that are subject to greater weathering than the sheltered main facades, and these returns require particular attention to the integrity of the stucco render and its paint finish. Keim mineral silicate paint in the Nash Cream palette provides the specified coating system, its chemical bonding mechanism ensuring adhesion to the hydraulic cement substrate without creating the impermeable film that would trap moisture in the wall construction. The Ionic column capitals of the entrance porches demand specialist attention: their relatively sheltered position encourages biological colonisation, and a biocidal pre-treatment may be necessary before paint application. The channelled rustication of the ground floors must be maintained during any repair work, with the V-profile grooves carefully recreated using a pointed trowel guided by a straight edge. Where the stucco has been damaged by impact — a common problem at ground-floor level — repairs should be carried out using NHL 5.0 hydraulic lime mortar matched to the original in colour and texture, applied in thin layers and allowed to carbonate before painting. The timber entrance doors, set within the Ionic porches, are relatively protected from weathering and require a linseed oil paint system with a high-gloss topcoat in a dark heritage colour — typically black or dark green. Sash windows throughout should be maintained with the standard linseed oil system, with glazing putty renewed using traditional linseed oil putty. The exposed stock brick of the return walls between villa pairs should never be rendered or painted, as the breathable brick surface provides essential moisture management for the wall construction.
