What this policy is about

Policy H6 restricts the conversion of family-sized homes under 130m2 into flats, but allows conversions of larger homes (over 130m2) into self-contained units if they meet certain standards, including quality of accommodation, mix of unit sizes, and minimal disturbance to neighbours.

Plain-English summary of the adopted policy text below. The full text is the rule; this is the gist.

The policy — as adopted

Residential conversions

A. To ensure mixed and balanced communities with a choice of family-sized housing and to manage the cumulative effects of residential conversions on environmental quality and local amenity, the council will protect dwellings suitable for occupation by families of less than 130m2 (as originally constructed) from conversion into flats. B. Where a dwelling has a floor area (as originally constructed) of at least 130m2, conversion of the property into self-contained units may be acceptable provided: i. the development provides a high quality of accommodation and each new self-contained unit meets the standards for new residential accommodation set out in Local Plan policy H5; ii. the proposal provides a mix of unit sizes including the provision, where practicable, of a family-sized home; at ground-floor level with direct access to a rear garden; iii. the conversion will not lead to an unacceptable level of noise and disturbance to occupiers and adjoining properties (see Local Plan policy Q2); iv. the cycle parking and refuse storage arrangements are adequate and do not, by design or form, adversely affect the quality of the street scene (see Local Plan policies Q12 and Q13); cycle parking standards in Local Plan policy T3 will also apply; v. where a Controlled Parking Zone is in place, no additional car parking permits will be issued to any occupiers of additional housing units created through the conversion; vi. where there is no Controlled Parking Zone the occupants of the additional housing units created will not be eligible for car parking permits in the event that a CPZ is introduced at a later date.

16 dismissed · 2 allowed — 18 PINS appeal decisions cite H6

From Planning Inspectorate decision letters that cite H6. Dismissed = the council's refusal stood, the policy held; allowed = overturned. The tighter join — this borough's own refusals citing H6 traced to their specific appeals — is still to come.

Citations, officer spread, ward and application-type counts parsed from published Lambeth decision notices (high-confidence parses, approvals and refusals), joined to the canonical application record. One citation = one decision citing the policy. See the policy overview for every policy cited.

Atlas intelligence summarises patterns and observations from published planning records. Past decisions do not indicate how any future application will be determined. Every application is assessed on its own merits, having regard to the proposal, site, evidence and policies applying at the time.
