Decorating Cambridge Terrace

Cambridge Terrace was designed by John Nash and constructed in 1825 as one of the smaller components of his comprehensive Regent's Park scheme. Named after Adolphus, Duke of Cambridge, the seventh son of George III, the terrace comprises a short row of houses on the southern section of the Outer Circle, positioned between Chester Gate and the York Terrace composition. Its relatively modest scale — both in length and in architectural elaboration — reflects its secondary position in the park's hierarchy of terraces, filling the gaps between the major set-pieces rather than commanding attention in its own right. This supporting role was integral to Nash's scenic conception: the park's perimeter required passages of visual repose between the climactic compositions, just as a musical work requires quieter passages between its themes. The original houses were of comfortable but not palatial proportions, attracting professional families and the minor gentry who valued a Regent's Park address without requiring the social statement made by residence on Cumberland or York Terrace. The terrace's relatively compact dimensions meant that it functioned as a more intimate community than the larger terraces, its residents sharing a closer neighbourly proximity. During the twentieth century, several houses were converted to flats, and some institutional uses were introduced, but the external facades remained substantially unchanged. The Crown Estate's restoration programme addressed Cambridge Terrace as part of the broader programme of stucco renewal that has progressively refreshed the Nash terraces over recent decades. Today the terrace provides desirable residential accommodation within one of London's most architecturally significant settings.

The decoration of Cambridge Terrace follows the Crown Estate's standard specification for Nash terraces, with Keim mineral silicate paint in the Nash Cream palette applied to all stuccoed surfaces. The terrace's more modest scale makes it a somewhat less complex project than the major terraces, but the same fundamental principles of substrate preparation and paint application apply. All existing coatings must be tested for adhesion and compatibility, with any failing material removed to a sound base. Areas of hollow or cracked render must be cut out and replaced with NHL 5.0 hydraulic lime mortar, matched to the original in aggregate profile and colour. The incised ashlar jointing must be carefully maintained during any repair work, using a narrow trowel to recreate the characteristic V-profile channels. The pediment and pilaster strips of the central feature require slightly more careful treatment than the plain facade surfaces, as their moulded profiles tend to accumulate soiling and biological growth in sheltered areas. Gentle brush cleaning followed by, where necessary, application of a quaternary ammonium compound biocide will prepare these surfaces for painting. The iron balconettes at first-floor level, being of relatively simple design, can be efficiently prepared using wire brushes and scrapers, with a protective system of zinc-phosphate primer and alkyd gloss finish in black. Timber sash windows require the standard linseed oil paint system, with particular attention to the putty fillets that seal the glass to the frame. The rear brick elevation should be maintained through lime-putty repointing where necessary, and must not be painted or rendered. Internal lime plaster should be decorated with breathable finishes: limewash, distemper, or modern clay-based paints that allow moisture vapour transmission through the wall construction.
