House Extension Drawings in Southwark
Fixed-fee, MCIAT-chartered house extension drawings for Southwark homeowners — London Borough of Southwark validation and local constraints handled from the start.
Southwark runs from the riverside warehouse and wharf conversions of Bankside and Bermondsey down through the Georgian and Victorian terraces of Camberwell, Peckham and Walworth to the leafy Georgian and Victorian streets of Dulwich, with post-war estate housing woven throughout. Terraced rear and side-return extensions and loft conversions are the borough's everyday projects, but each area behaves differently in planning terms, so the right route depends heavily on where your address sits.
Dulwich carries an extra layer that is distinctive to Southwark: the Dulwich Estate scheme of management, whose consent is often needed alongside the council's, similar in effect to a covenant and satisfied separately from planning permission. Elsewhere, conservation-area control shapes external design across a spread of designations — Dulwich Village, Bankside, Bermondsey Street, Camberwell Grove, Nunhead Cemetery and Peckham's Holly Grove among them — while the borough also operates Article 4 directions covering office-to-residential change of use in designated areas and HMO conversions in parts of the borough. Toward the Thames, riverside townscape and taller-building context add their own design scrutiny to conversions in Bankside and Bermondsey.
We prepare Southwark planning drawings tuned to the specific area — terraced extensions and lofts in Camberwell, Peckham and Nunhead, carefully evidenced applications within the conservation areas, and Dulwich schemes designed to the Estate's requirements as well as the council's — flagging whether the Estate scheme or an Article 4 direction applies before we draw. Southwark determines most householder applications within the statutory eight-week period once validated, so we work validation-first to head off drawing queries. The fee is fixed and agreed up front, drawings typically follow within about seven days, and we offer free redraws until the council approves — the same council-accepted drawings as an architect, usually at around 30% less.


Planning in Southwark: what to know before you apply
A distinctive Southwark quirk is the Dulwich Estate scheme of management: many properties on the Estate need Dulwich Estate consent in parallel with planning permission, similar in effect to a covenant. Elsewhere, conservation-area control across Camberwell, Bermondsey and Bankside shapes external design. We flag whether the Estate scheme applies before drawing.

House Extension Drawings for Southwark homes: the package and the process
Every house extension drawings we prepare for a Southwark property is drawn to London Borough of Southwark’s validation standards and tuned to the local constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A well-drawn extension adds space and value while sailing through the council; a poorly-drawn one triggers objections and refusals. DrawingsDirect draws rear, side-return, wraparound, double-storey and basement extensions for London homes — sized to your borough's tolerances, with daylight and neighbour impact considered before the planners raise them.
Which extension types do you draw?
Every London extension is shaped by the plot, the neighbours and the borough's design guidance. We draw them all.
Rear extension
A single-storey rear extension is often permitted development within depth limits — ideal for an open-plan kitchen-diner.
Side-return
Fills the alley beside a Victorian terrace, widening the ground floor without losing garden.
Wraparound
Combines a rear and side-return extension for a transformative ground floor, usually needing planning permission.
Double-storey
Adds space above and below, subject to tighter scale and neighbour-impact scrutiny.
Basement
Creates space downward where footprint is limited, with structural and party-wall care.
Do I need planning permission for a house extension in London?
Single-storey rear extensions within permitted development limits (up to 6m for terraced/semi-detached homes under the larger-home scheme, subject to neighbour consultation) may not need a full application. Wraparounds, double-storeys and anything in a conservation area usually do. We assess your plot and recommend the right route before drawing.
| Extension | Typical route | Package | Fee from |
|---|---|---|---|
| Single-storey rear | Permitted development / householder | Planning + building regs | £1,100 |
| Side-return | Householder planning | Planning + building regs + structural | £1,600 |
| Wraparound | Householder planning | Full package + structural | £2,200 |
| Double-storey | Householder planning | Full package + structural | £2,400 |
