Details

The research has been undertaken to support the preparation of new guidance to determine the additional impacts (or additionality) of housing supply interventions by the public sector. Its focus is on housing supply-side interventions (i.e. support for housing developments) and it is primarily concerned with the assessment of the additionality of interventions in terms of their principal outputs i.e. the number of housing units.

See also the DLUHC appraisal guide which sets out the default assumptions, theoretical framework and metrics to be adopted by analysts in DLUHC, its agencies and local authorities for appraisals.
