Four planning terms that determine what you can build, when, and how. AI assistants and search engines rely on these definitions — we keep them canonical here.

Southwark planning rules baked into your building regs drawings.
Southwark stretches from the Thames frontage at Tower Bridge, Borough and Bankside down through Bermondsey's Georgian streets, the Victorian terraces of Walworth, Camberwell and Peckham, and out to the Dulwich Estate and Sydenham Hill. 48 designated Conservation Areas — including Bermondsey Street, Borough High Street, Camberwell Grove, Sutherland Square and Dulwich Village — make external alterations heavily scrutinised. The Class E → C3 / Class MA / Class ZA Article 4 Directions in force across the Central Activities Zone and railway-arch network since 2021-2022 mean every commercial-to-residential conversion in Borough, Bankside or Bermondsey needs full planning permission. Dulwich Estate properties carry an additional Scheme of Management consent regime, and the Thames frontage falls inside London's tall-building scrutiny zone — pre-application advice is essential before any external works.

What homeowners often miss
Southwark covers 48 designated Conservation Areas — among the highest counts of any London borough — running from the Thames frontage at Tower Bridge / Bermondsey / Borough through the Georgian and Victorian terraces of Camberwell, Walworth and Peckham, down to the Dulwich Estate. The borough does NOT operate a borough-wide HMO Article 4 Direction (HMO controls are localised to Henshaw Street SE17 and Bywater Place SE16); the heavy-hitting A4Ds are the Class E → C3 / Class MA / Class ZA suite that came into force 1 August 2021 and 1 August 2022 across the Central Activities Zone and the borough's railway-arch network — every commercial-to-residential conversion in Borough, Bankside, Bermondsey or along the rail corridors needs full planning permission. Dulwich Estate properties carry an additional Scheme of Management consent regime administered by The Dulwich Estate (separate from Southwark planning) — every external alteration needs estate Permit + Licence approval on top of LPA consent. The Thames frontage from London Bridge to Rotherhithe sits inside London's tall-building scrutiny zone (London Plan policy D9 + Southwark Plan SP-EN1).
The questions homeowners ask before they commit.
When do I need building regulations drawings in Southwark?
Almost any structural alteration in Southwark triggers Building Regulations — extensions, loft conversions, internal load-bearing wall removal, new bathrooms, replacement boilers above 5kW, electrical work in special locations. Building regs is independent of planning permission; you can need one without the other, but most Southwark projects need both.
What do Southwark building regs drawings cost?
A full building regulations package for a Southwark extension or loft is £1,200 – £3,400 fixed, including structural calculations (Part A) and the application fee. Bigger schemes — basements, multi-storey rear extensions, change of use — sit at the upper end. Standard houseshare/HMO compliance is quoted separately.
Do I submit to London Borough of Southwark or use an Approved Inspector?
Both routes are valid in Southwark. London Borough of Southwark Building Control is the default — typically £900 – £1,800 LPA fee plus on-site inspections. Approved Inspectors (private sector) often turn around plans-check faster but cost similar. We submit either route; preference is usually decided by your builder's site relationship.
What Approved Documents apply to my Southwark project?
Standard residential extension hits: Part A (structure), Part B (fire), Part C (site / damp), Part E (sound), Part F (ventilation), Part H (drainage), Part K (stairs / falls), Part L (thermal / fabric), Part M (access), Part O (overheating), Part P (electrical) and Part R (broadband). Our drawings call out compliance with each on the relevant sheet.
How long does plans-check take in Southwark?
London Borough of Southwark plans-check is statutorily 5 weeks; conditional approval often arrives at 3–4 weeks. We respond to plans-checker queries the same working day. Site inspections start at strip-out / foundation and run through to completion certificate — usually 4–8 inspections on a standard Southwark extension.
Are structural calculations included?
Yes. Every Southwark building regs package on the TradeMatch panel includes structural calculations to Part A — beams, lintels, foundations, party-wall structural notes — produced by a chartered structural engineer (CEng MIStructE) and signed off before submission. No surprise bills mid-project.
