Policy test

Number of homes and site area

Settles the major threshold and feeds the density calculation. The L3(2)(c) floor is measured over the net developable area, which on a small site is normally the whole site, so the site area is used.

Where does the site sit?

Decides which policy family applies. The council's policies map shows settlement boundaries and Green Belt.

Land and buildings

Tick as many as apply: each opens a different limb, and they are alternatives, not a hierarchy.

What kind of housing is proposed?
Scale of development

Major for housing is 10 or more homes, or a site of 0.5 hectares or more. Either limb is sufficient. Strategic is a defined term: phased, masterplanned, significant infrastructure.

Evidenced unmet need

Unmet need is not defined, but it must be evidenced. Inside the Green Belt, footnote 41 narrows it to the two supply measures. Annex A(3) closes one argument outside it: where the council has a five year supply and a Housing Delivery Test result above 75%, a standard method figure higher than the adopted plan requirement does not count as unmet need for five years from adoption.

Is the site within reasonable walking distance of a station?

Reasonable walking distance is around 800 metres. Where topography, poor routes or a physical barrier would put that walk off, around 10 minutes' actual walking time is used instead. Where only part of the site is within reach, the station limbs and the density floor apply only to that part.

Design quality

DP3 attaches weight to design quality generally, and is not confined to isolated sites. Separate from the HO11(1)(e) route.

Constraint screen

Tick anything engaged, not merely nearby.

Which heritage assets would the proposal affect, including through development within their setting?

Record every asset affected: they attract different policies and can take different levels of harm. Where more than one asset of the same type is affected, assess the one that would take the greatest effect.
