What Redbridge Council asks of a flat conversion

From the council's Redbridge Local Plan 2015-2030, Policy LP6 (Dwelling Conversions, HMOs and BMROs) (adopted adopted by Full Council on 15 March 2018).

  • The Redbridge Local Plan 2015 to 2030 was formally adopted at Full Council on 15 March 2018 and is shown on the council's website as the current Local Plan. (source, checked 25 October 2026)
  • Policy LP6 supports the conversion of larger homes into smaller self-contained units only where the property is in a Metropolitan, District or Local Centre as identified in Appendix 6 of the plan. (source, checked 25 October 2026)
  • The gross floor area of the property must exceed 130 square metres where two units are proposed and exceed 180 square metres where three or more units are proposed. (source, checked 25 October 2026)
  • The conversion must provide at least one larger family-sized home of 74 square metres (3 bed plus) on the ground floor with access to a dedicated rear garden, and meet the national space standards. (source, checked 25 October 2026)
  • Policy LP6 also requires that there is no significant loss of character or amenity from increased traffic, noise or disturbance, and car and cycle parking in accordance with London Plan standards; over-concentration is judged by cumulative impact on parking, noise, overcrowding and waste. (source, checked 25 October 2026)

What Redbridge flat conversion drawings have to show

Redbridge decides a flat conversion on location first, so we check your address against the centres in Appendix 6 of the Local Plan before measuring anything. Then the arithmetic: gross floor area against 130 square metres for two flats or 180 square metres for three or more, and where the 74 square metre three-bed ground-floor flat and its dedicated rear garden would go.

The drawings show each flat against the national space standards, the garden divided so the family flat keeps its own, and parking and cycle storage set out to London Plan standards. Because Redbridge looks at how many conversions the street already has, we list the neighbours' conversions we can find alongside the plans.

Answers

Redbridge flat conversion questions

Where can I convert a house into flats in Redbridge?
Policy LP6 of the Redbridge Local Plan supports conversions only in Metropolitan, District or Local Centres, which are listed in Appendix 6 of the plan. The property must also exceed 130 square metres of gross floor area for two units, or 180 square metres for three or more, so the address is checked first.
How big must a house be to convert to flats in Redbridge?
The gross floor area must exceed 130 square metres where two units are proposed and 180 square metres where three or more are proposed. The conversion must also provide a family-sized home of 74 square metres, three bedrooms or more, on the ground floor with its own rear garden, and meet the national space standards.
Does Redbridge limit how many conversions a street can have?
Policy LP6 asks whether the conversion causes a significant loss of character or amenity, and the supporting text says Redbridge looks at the cumulative impact of parking, noise, overcrowding and waste on the street scene when judging over-concentration. It sets no percentage, so we record the existing conversions on your road.
