5.4 Replacement

The basis of renewal should be like-for-like replacement using traditional materials and methods: wattle and daub should not be substituted by materials that are more commonly understood by modern contractors, such as lath and plaster. Various schemes involving the introduction of modern materials have been suggested by certain conservation publications, but the justification for these is usually unfounded.[97] The only scenario under which upgrading wattle and daub is warranted is a change of use of an unlisted building. In this case, the upgrading may be required to meet the requirements of the building regulations (See Section 5.5).

[97] An analogy would be to consider replacing the base of a decayed but hidden historic timber post with a reinforced concrete column since it improves durability of the structure as a whole!
