    Why Article 4 matters in Lewisham

    An Article 4 direction withdraws a named right, such as changing a window or altering a front wall. Lewisham's 57 directions cover 89 mapped areas, so the odds that one touches your street are real.

    The effect is practical. Work that would need no application in another borough may need one here, and we find that out before we draw anything. If you are unsure, a Lawful Development Certificate in Lewisham is the formal way to settle it.

    The borough also has an HMO Article 4 direction, so turning a house into a small shared house needs consent.

    Conservation areas, listings and a world heritage site

    There are 30 conservation areas in the borough, and inside them many everyday changes to roofs, windows and front walls need consent.

    Historic England lists 367 entries here: 2 at Grade I, 30 at Grade II* and 333 at Grade II. The council's data shows 1 World Heritage Site touching the borough, and 21 entries sit on the Heritage at Risk Register.

    Homes near the heritage edge may need a setting statement as well as ordinary drawings.

    A mixed borough of houses and flats

    Of 122,392 households, 42.2 per cent live in a house or bungalow and 41.9 per cent own their home. That puts Lewisham between the flat-heavy inner boroughs and the house-led outer ones.

    Terraced houses averaged £602,116 at the latest Land Registry count. Flats averaged £376,322, and owners of those flats need an application for most external changes.

    The plan and guidance we draw to

    The borough has a recent plan, the Lewisham Local Plan 2020-2040, adopted in 2,025. Householder design advice comes from the Alterations and Extensions SPD, and the Small Sites SPD is relevant if your plot could take another home.

    The council's page does not state whether the alterations guide covers roofs or basements. We read the plan policy for those elements and cite it on the drawing notes.

    What Lewisham's figures show

    Lewisham decided 578 householder applications in its latest twelve months and granted 89.4 per cent, with 95.2 per cent decided in time.

    That describes the borough's past decisions and not your project. A clear drawing set and a short design note remain the best preparation.

    The Mayor's levy for Lewisham is band 2 at £72.73 per square metre this year. The local schedule is the London Borough of Lewisham CIL Charging Schedule.

    What we do for a Lewisham application

    Our process is built around Lewisham's pattern of controls. The first step is a free check of your address against the Article 4 map, the conservation areas, the listing record and the World Heritage Site setting.

    If a permitted route exists, we say so, and we can prepare the Lawful Development Certificate that proves it. If not, we draw a householder application to the borough's Alterations and Extensions guide.

    Every set is checked by someone other than the drafter before it leaves us. Your price stays fixed from the quote onward, and the council's fee is the only other payment on the application.

    After consent we can produce the building regulations drawings, so the structure, insulation and drainage match what the council approved.
