Walling materials

Rough textured cement finishes or pebbledash were used on many early houses and cottages, for example in Asmuns Hill, Temple Fortune Hill and the Temple Fortune end of Hampstead Way. A pebbledash finish was generally left unpainted, and weathered to yellow brown over the years. Together with green, black, white or cream painted woodwork, this gave a harmonious appearance, particularly to groups. The visual unity of terraces, groups and semi-detached properties should be respected. Painting walls a radically different colour or painting over previously unpainted surfaces is likely to be unacceptable.

Yellow London stock bricks were used in Asmuns Place, for example, with contrasting orange brick arches or tile creasing. Red or purple stock bricks were used for the more expensive houses, and for features such as chimney stacks on others. Matching the brickwork should not present problems. It is essential to match the jointing or pointing. Most brickwork up to the 1930s used a lime mortar (with a little cement). A flush joint was cut off as work proceeded, leaving a rough texture which has since weathered back. Modern bricklaying often involves pointing up afterwards and smoothing the mortar with a steel trowel. This produces a markedly different appearance. Repointing presents its own problems. Please discuss these with the Trust Architect. It is desirable to copy the brick bonding so that new work matches the old.
