Flat conversion drawings in Waltham Forest
A Waltham Forest house can become flats only with planning permission, because using a former single dwellinghouse as two or more separate dwellinghouses is a material change of use; a loft on a house that stays one home is a different application. We draw a two-flat conversion from £1,195, and the council's fee is £610 for each additional dwelling.
Fixed fee from £995 drawings + £200 survey (£1,195 total) · all prices

What the application is for
Section 55(3)(a) of the Town and Country Planning Act 1990 makes the use as two or more separate dwellinghouses of a building previously used as a single dwellinghouse a material change of use. The application is for that change, and the drawings are the evidence: each flat on its own plan, the shared parts, and any change to the outside.
The full wording is on legislation.gov.uk, and our guide to planning permission for converting a house into flats sets out how councils apply it.
Money: two fees to plan for
The council's planning fee has been £610 for each additional dwellinghouse since 1 April 2026, where fewer than 10 dwellinghouses are created (SI 2012/2920, category 12(1)(a)). A house into two flats adds one.
Ours is fixed: £1,195 is the starting point for a house to two flats, drawn for full planning and for Building Regulations. Larger conversions are on the pricing page.

Appeals and conservation areas
Our analysis of the Planning Inspectorate Casework Database (released 1 Oct 2026, Casework Database 2609) counts 193 householder appeals in Waltham Forest decided between 2021 and 2026, of which 36% were allowed. They are householder cases and not conversions.
Our analysis of the MHCLG Planning Data Platform (bulk snapshot retrieved 14 Aug 2026) finds 15 conservation-area entries for Waltham Forest on the national register. The council's conservation area map shows whether your house is inside one. Our glossary entry on conservation areas explains what that changes.
A loft in the same scheme
A loft conversion in Waltham Forest can be part of a flat scheme or a project of its own. If the loft is part of the conversion, for example an upper flat that uses the roof space, tell us at the start so both are drawn together. If it is a loft on a house that stays as one home, use our loft conversion drawings service instead.
