Space standards in affordable housing in England

Abstract

ABSTRACT This paper examines the state of affordable housing in England, with a focus on regional variations in space standards and standardized dwelling layouts widely used by volume housebuilders. Space standards are not statutory and therefore adopted inconsistently across development types or building typologies in England. The study draws on data obtained from planning applications, analysing 153 housing developments and 9876 newly constructed affordable housing units from different regions in England that were completed and marketed in 2021. Based on this, the study compares space standards and their effectiveness as well as the use of standardized unit types. The analysis reveals that apart from London, the most recent Nationally Described Space Standard (2015) is not yet widely used. Instead, Housing Quality Indicators that preceded the new national standards continue to be the norm for houses built outside of London. The findings demonstrate that there is a high level of standardization in affordable housing in terms of dwelling size and layout, with widely used standard house types often determining the design and size of dwellings more than space standards.
