Planning in Southwark — the detail
Southwark spans two planning worlds: the dense, listed riverside from Bankside and Borough through Bermondsey Street and the Tower Bridge conservation areas, and the leafy Victorian and Georgian terraces inland — Camberwell Grove, Dulwich Village, the Sunray Estate, Trinity Church Square and dozens more among its conservation areas. The terrace belts of Camberwell, Peckham, Dulwich and East Dulwich are active rear-extension, side-return and loft territory; the riverside is heritage-led and frequently listed.
Southwark's Article 4 regime is unusual and worth understanding. The great majority of its directions protect public houses — removing the right to demolish, alter or change the use of a pub — and shopping frontages, and control commercial-to-residential conversion; they are not householder extension restrictions. For homeowners, the controls that actually narrow what you can build are conservation-area designation and, in listed stock, listed building consent. The council's Residential Design Standards SPD sets the detailed expectations for extensions and alterations.
Where a terraced house sits outside a conservation area, permitted development and prior approval carry many rear and loft projects; inside the conservation areas, full applications are the norm and roof form and materials decide outcomes. As across inner London, a large share of the stock is flats, where permitted development does not apply and a licence to alter is needed.
Policy detail lives in the Southwark local plan and applications are submitted via the Southwark planning portal.

Article 4 directions in Southwark
Real · planning.data.gov.ukSouthwark records hundreds of Article 4 directions, but they overwhelmingly protect public houses (from demolition, alteration or change of use), protected shopping frontages, and commercial-to-residential conversions and site allocations — not householder permitted development. For homeowners, conservation-area designation and listed status are what narrow extension rights; check the area report for what applies at a specific address.
