Ex-pub conversion — Brixton ACV-listed corner pub to 4 self-contained flats

Brief

1894 Victorian corner public house SW2 Brixton — closed 2022 after 4-year decline + COVID. Sui Generis use class A4 (public house). ACV-listed (Assets of Community Value) by Brixton Society + Friends of The Coronet community group 2023. Owner sold 2024 to developer client. First application 9-flat scheme + roof extension refused by Lambeth Council 2024 — overdevelopment + heritage harm + ACV non-compliance. Builderr engaged 2024 for retry application — minimum viable scheme to clear ACV + planning + heritage hurdles, retain community value pub features as design narrative. 4 self-contained C3 flats — ground 1-bed + first 2-bed + second 2-bed + lower-ground 1-bed studio. NPPF para 92 marketing test + ACV moratorium + Brixton CA + Article 4 + Lambeth Local Plan Policy H6 (loss of community facility). Successful permission 2025 after 11-month pre-app + 14-week determination.

Challenge

5 distinct + concurrent challenges: (1) ACV moratorium — building listed Asset of Community Value under Localism Act 2011 by Brixton Society + Friends of The Coronet (250+ supporter group). 6-week moratorium triggered on intention-to-sell notice 2023; community group attempted bid + raised £180k of £950k target via crowdfunding but fell short. Moratorium expired but ACV listing retained — material consideration in planning. Lambeth Local Plan Policy H6 explicit on protecting community facilities. (2) NPPF para 92 marketing test — required to demonstrate pub no longer viable as community facility. CAMRA + Lambeth Council prescribed: 12-month marketing at evidenced market rent (independent valuer £85k pa rent assessment) + 6-month marketing at concessionary rent (£55k pa) for community-led restart. Marketing campaign Q4 2024 + H1 2025 — 47 enquiries, 4 viewings, 0 offers. Marketing report 89 pages submitted to LPA. (3) Heritage — Brixton Conservation Area + Article 4 direction (no PD rights including class MA pub-to-resi); building locally listed for architectural + community interest. CA officer required: retain ground-floor frontage + tile dado + etched mirrors + bar-back joinery (re-purposed); retain 1st + 2nd floor cornices + ceiling roses + arched windows; no roof extension or mansard; reuse rather than dispose of internal Victorian features (offered to community via Friends of The Coronet on 30-day notice for any element to be removed). (4) Lambeth refused first 9-flat scheme (2024) on grounds: overdevelopment (9 too many for footprint + amenity), insufficient affordable contribution (need 35% for >10 units but 9 just below threshold = avoidance tactic per LPA), heritage harm to CA, inadequate amenity space + privacy. Resubmission strategy: reduce unit count to 4 (genuinely viable not just threshold-dodging), maximise heritage retention as positive narrative, demonstrate Section 106 contribution despite small scheme. (5) Build complexity — Sui Generis to C3 requires full residential build-up: Part E acoustic separation (56 dB airborne, 62 dB impact) between dwellings; Part B fire compartmentation + 30/60-minute fire-resisting walls + floors + protected stair; Part L thermal upgrade including external wall insulation (CA-restricted to internal); Part F ventilation each dwelling; Part G plumbing + drainage 4 separate consumer units + 4 separate heating systems; Part M accessible visiting standards on ground floor; new external stair for upper flat access required by Lambeth officer (refused fire-only access from primary stair).
