Architects and Interior Designers in Southwark

Southwark is one of London's most varied boroughs to build in. A Victorian terrace off Lordship Lane in East Dulwich (SE22), a Georgian townhouse in Trinity Church Square (SE1) and a converted warehouse on Bermondsey Street (SE1) each come with a different structure, a different planning history and a different set of neighbours to work around.

Doll & Co. is a RIBA Chartered Practice. Our architects and interior designers in Southwark work as one team from the first sketch, so the planning strategy, the structural approach and the finished interior are resolved together rather than handed from one specialist to the next.

Architectural Services in Southwark

Our architectural services in Southwark cover feasibility, pre-application advice with Southwark Council, planning, building regulations and construction oversight, across the borough's terraces, warehouse conversions and Georgian squares alike.

Our Architectural Services page sets out this process in full, from feasibility through to completion.

Loft Conversions in Southwark

The borough's Victorian and Edwardian terraces, concentrated around Peckham, Nunhead and East Dulwich, are well suited to dormer and hip-to-gable loft conversions, and many fall within permitted development where the roofline is unbroken by a conservation area designation. Where a street sits within the Dulwich Village or Camberwell Grove conservation areas, the design needs to respond to the existing roofscape and a planning application is required regardless of size.

Basement Extensions in Southwark

Southwark does not apply a single borough-wide basement policy in the way some central boroughs do, but flood risk is a genuine constraint close to the Thames, around Bankside, Borough and Rotherhithe (SE1 and SE16), where a flood risk assessment is typically required before a basement scheme can proceed. Further from the river, in Peckham (SE15) and Dulwich (SE21/SE22), basement extensions are judged more on structural impact to neighbouring properties and on the loss of garden amenity space.

Rear, Side Return and Warehouse Conversions in Southwark

Many Southwark terraces, particularly around Nunhead and East Dulwich, have the same narrow side returns found across London's period stock, and a glazed infill extension can transform a dark kitchen into the centre of the home. Closer to the river, around Bermondsey Street and Borough, our work more often involves converting former warehouse and industrial buildings into residential lofts, which brings a different set of structural and acoustic questions than a domestic terrace.

Listed Buildings and Conservation Areas in Southwark

Southwark's conservation areas range from the Georgian terraces of Trinity Church Square to the industrial character of Bermondsey Street and the village scale of Dulwich Village. Listed building consent applies to internal as well as external works, and we prepare the heritage statements needed to protect original features while adapting these buildings for modern family life.

Interior Design Services in Southwark

Our interior design services in Southwark run in parallel with the architecture, not after it. Ceiling heights, beam positions and service routes are agreed with the joinery, lighting and furniture layout already in mind, which keeps late and costly changes off the site programme.

Typical work includes bespoke kitchens that open onto gardens in Dulwich and Peckham, loft conversions finished with concealed climate control and built-in storage, and warehouse conversions near Borough and Bermondsey Street where exposed structure is balanced against a comfortable, liveable interior.

Planning Permission in Southwark

Southwark Council's planning position varies considerably across the borough. Conservation areas including Dulwich Village, Camberwell Grove, Trinity Church Square, Bankside and Bermondsey Street carry tighter controls on materials, roofline and street-facing alterations, while many streets in Peckham and Nunhead retain fuller permitted development rights.

We recommend pre-application advice for any scheme in a conservation area or close to the river, and we build the party wall process, typically 8 to 12 weeks, into the programme from the outset. Properties near the Thames, including parts of Bankside and Rotherhithe, should expect flood risk to be assessed early, as it can affect both basement design and ground-floor layout.

Frequently Asked Questions

Do I need planning permission for a loft conversion in Southwark?

It depends on the street. Many properties in Peckham and Nunhead retain full permitted development rights, so a dormer or hip-to-gable conversion can often proceed without an application. Where a street sits within the Dulwich Village or Camberwell Grove conservation areas, a full planning application is required regardless of size.

Do I need a flood risk assessment for a basement in Southwark?

Often, yes, if the property is close to the Thames. Areas including Bankside, Borough and Rotherhithe sit within flood zones where Southwark Council typically requires a flood risk assessment before a basement scheme can be approved. Further from the river, in Peckham and Dulwich, the main constraints are structural impact on neighbours and loss of garden amenity space.

Which conservation areas cover Southwark?

Southwark's conservation areas include Dulwich Village, Camberwell Grove, Trinity Church Square, Bankside and Bermondsey Street, each with different expectations: village-scale materials in Dulwich, Georgian uniformity around Trinity Church Square, and industrial character along Bermondsey Street.

Can I convert a warehouse into a home in Southwark?

Yes, this is common around Bermondsey Street and Borough, where former industrial buildings are frequently converted to residential use. These projects raise different questions than a domestic terrace, particularly around structural loading, acoustic separation between units, and retaining the character features that often justify the building's conservation status.

How long does planning permission take in Southwark?

A straightforward householder application typically takes 8 to 13 weeks from validation to decision. Schemes in a conservation area, near the river, or requiring pre-application advice usually take longer, and we build the party wall process, a further 8 to 12 weeks, in alongside it.
