Purpose and intended audience
The updated guidance is less specific than the 1996 guidance in terms of what repairs and alterations are likely to be acceptable in practice. As with the move from PPG15 to the NPPF in 2012, the new guidance adopts a principles-based approach where its predecessor dealt with specifics. This is fine for the professional, but one wonders whether homeowners may be disappointed not to find more specific advice, particularly if they are looking to carry out sensitive repairs or alterations themselves.
Time period: 1715-1900
The guidance notes that the period of houses at which the guidance is aimed is 1715 – c.1900. We welcome the inclusion of terraced houses from 1860-1900 in this guidance, as there are many examples of late Victorian and Edwardian terraced houses which are under-appreciated due to claims that their standardisation renders them of lesser architectural and historic interest.
The First World War formed a watershed, after which there was a move to lower density suburban housing in the form of Homes for Heroes and the garden city movement. These were seen as measures for achieving healthy living, in accordance with early town planning principles which expounded the benefits of lower densities.
Perhaps a bracket of up to c.1914 would appear to be a more logical approach for the guidance on terraced housing, as some towns outside of London—particularly those with high population pressures such as Plymouth and Portsmouth—continued to build terraced houses designed by local architects during the Edwardian period (see Figure 1).

Legislation/policy compliance
It’s noted in the introduction that this guide will be of most use to those dealing with requests for listed building consent, though the document will also be of use for other historic terraces which aren’t listed but may be included in conservation areas.
It omits note of the general lack of designation for late-Victorian and Edwardian terraced houses. These houses fall outside the 1850 date beyond which the DCMS ‘Principles of Selection’ (November 2018) notes that ‘greater selection’ for listing is required. Given the limited extent of listed building designation for terraced housing, it might be helpful to include a brief policy compliance section, outlining what is permissible for listed terraced houses; those in conservation areas; and those which are locally listed or non-designated. It may also be useful to note that some terraced houses are subject to restrictive covenants which control changes to their appearance or built form, for example in Tothill Avenue in Plymouth (see Figure 3).
Helpfully, the document highlights the Party Wall Act for Houses of Multiple Occupation, which must be complied with. It also encourages engagement with the local authority in accordance with best practice.
