What this policy is about
Policy Q15 requires boundary treatments in Lambeth to be sympathetic to local character, with specific height restrictions for residential and non-residential areas. The council will resist boundary height increases unless well-designed and consistent with local character. It will support replication of positive local boundary treatments.
Plain-English summary of the adopted policy text below. The full text is the rule; this is the gist.
The policy — as adopted
Boundary treatments
A. The council will seek to retain boundary treatments that are characteristic of the immediate locality, are historically unique or contribute to local distinctiveness.
B. Where replacement is considered appropriate, and in new development, the council will expect: i.
replication of positive locally distinct boundary treatments and a sympathetic response to its context in terms of height, design and appearance;
ii.
front boundaries in residential areas and those between front gardens not to exceed 1.2 metre in height (unless specifically justified by the character of the locality or specialist function of the development);
iii.
front boundaries in non-residential areas not to exceed 2 metres fronting the street (unless specifically justified by the character of the locality or specialist function of the development) and to be open in character rather than solid;
iv.
rear boundaries between gardens and sites not to exceed 2 metres; and
v.
boundaries flanking a vehicle crossover to not exceed 900mm in height (to maintain sight lines).

C. The raising in height of existing boundaries will only be supported where it is undertaken in a well designed and carefully detailed manner which is consistent with local character and not discordant.

From Planning Inspectorate decision letters that cite Q15. Dismissed = the council's refusal stood, the policy held; allowed = overturned. The tighter join — this borough's own refusals citing Q15 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.
