Flat conversion drawings in Redbridge
Converting a Redbridge house into flats is a change of use that needs planning permission, and the application stands or falls on the drawings. DrawingsDirect, MCIAT chartered architectural technologists, draws the existing and proposed plans, elevations and sections for Redbridge flat conversions, with house to two flats drawings from £1,195.

Why a Redbridge flat conversion needs planning permission
The Town and Country Planning Act 1990 settles the point in section 55(3)(a): when a building previously used as a single dwellinghouse comes to be used as two or more separate dwellinghouses, that involves a material change in the use. A conversion into two or more flats therefore needs planning permission, and a householder application will not cover it.
Our guide to planning permission for converting a house into flats explains the test, and what the council looks at beyond the drawings.
Drawings that show each flat working on its own
The case officer needs to see each flat laid out on its own plan, with its entrance, how the shared areas work and what changes on the front and rear elevations. We draw the existing building and the proposal to the same scale so the two can be compared directly, with sections where levels matter.
A conversion is a retrofit of the existing house, so the Building Regulations drawings deal with upgrades such as fire separation and sound insulation between the flats. They are developed from the planning set, so what is drawn for planning is not wasted. See our building regulations drawings service for that stage, or the flat conversion drawings service page for what each set contains.

How busy Redbridge is, and what it decides
Our analysis of MHCLG planning application statistics, table PS2 (released 24 Sep 2026, quarters to 2026 Q2) shows Redbridge decided 1,638 planning applications of all types over the four quarters from 2025 Q3 to 2026 Q2.
The decision period for an application that is not major development is 8 weeks beginning with the day immediately following receipt (DMPO 2015, article 34(2)(b)). For the wider process, see our planning permission service.
Redbridge appeals: what the record says
Our analysis of the Planning Inspectorate Casework Database (released 1 Oct 2026, Casework Database 2609) counts 536 Redbridge planning appeals decided between 2021 and 2026, excluding enforcement, withdrawn and invalid cases. 28% were allowed.
Those 536 cases cover every kind of development, so treat the rate as context rather than a guide to conversions. What a conversion can control is the first set of drawings: use it to put the quality of each flat, and the neighbours' amenity, beyond argument.

Conservation areas in Redbridge
Our analysis of the MHCLG Planning Data Platform (bulk snapshot retrieved 14 Aug 2026) finds 19 conservation-area entries for Redbridge on the national register. Redbridge Council's conservation area map shows whether your house falls in one; if it does, changes to the front elevation of a conversion are looked at closely.
Our guide to conservation area extension rules in London explains how a designation changes what you can do.
