Peckham (SE15) in Southwark centres on the busy Rye Lane shopping street but is surrounded by genuinely fine housing — most notably the complete early-Victorian terrace of Holly Grove and the well-kept Bellenden Road streets. Rear and loft projects are common on the Victorian terraces, while the town-centre streets carry a different, retail-focused set of controls.

The Holly Grove and Rye Lane Peckham conservation areas are the defining designations here, and Southwark's Article 4 directions in SE15 largely govern the major town centre and protected shopping frontages rather than householder work. We establish which context a Peckham property sits in before drawing.

Planning in Peckham (SE15): what to know before you apply

Southwark's SE15 Article 4 directions mainly cover Peckham's major town centre and protected shopping frontages rather than household extensions, so many Peckham terraces retain permitted development rights — but the Holly Grove and Rye Lane Peckham conservation areas closely control elevations and rooflines within their boundaries, and the Peckham Rye frontages add open-space and tree considerations.

Typical Peckham housing stock

Fine early-Victorian terraces around Holly Grove and the Bellenden Road renewal streets, denser late-Victorian terraces toward Peckham Rye, and post-war estates north of the town centre.

Building Regulations Drawings for Peckham (SE15) homes: the package and the process

A Full Plans submission is a technical argument, not a picture. The sheets carry construction build-ups for floors, walls and roof, insulation values and junction details, drainage runs and invert levels, fire escape routes and protected stairs, ventilation provision and the structural elements that carry it all. Building Control checks each against the Approved Documents before work starts.

We draw the engineer's structural design onto the architectural sheets, so the beam sizes on the calculations are the beam sizes on the sections, and the openings your builder prices are the openings that were approved. Where a detail is unusual, we draw it rather than leave it to be resolved on site.

Construction details follow the existing fabric. Solid brick walls, suspended timber floors and uninsulated roofs each need a different build-up to reach the required performance, and a terrace has party wall junctions to detail that a detached house simply does not.

What do building regulations drawings cover?

A building control package translates the approved design into a buildable, compliant specification.

  • Construction sections and detailed junctions
  • Structural drawings and calculations (steel beams, foundations, loadings)
  • Part L thermal performance and insulation specification
  • Fire safety — escape routes, protected structure, alarms
  • Drainage and ventilation layouts

Full Plans or Building Notice — which should I choose?

A Full Plans application has your drawings checked and approved by Building Control before work starts, giving certainty and a document lenders and buyers like to see. A Building Notice lets simpler work start sooner but is inspected as it proceeds, with less up-front certainty. For most London extensions and loft conversions we recommend Full Plans, and prepare the package accordingly. Building regulations are a separate consent from planning permission, and the two are often confused — the explainer on permitted development rights sets out which projects escape a planning application but still need building-regs approval.

Why coordinate structural calculations with the drawings?

When the engineer's steels, padstones and bearings are drawn onto our own sheets, the steel schedule matches the drawings and the builder never waits on a missing detail. It closes the classic gap between one firm's drawings and another firm's calculations that nobody has checked against them.

FAQ

Building Regulations Drawings in Peckham SE15 — FAQs

Do I need building regulations approval as well as planning permission?+
Almost always, yes. Planning permission covers what the building looks like; building regulations cover how safely it is built. Most extensions and loft conversions need both.
How long does Building Control approval take?+
A Full Plans application is typically assessed within about five weeks. We prepare a complete package and respond to any conditions promptly, so approval is not held up by missing detail.
Can building regulations drawings be done after planning approval?+
Yes. Many homeowners secure planning permission first, then commission the building regulations package before starting on site. We can pick a project up at either stage.
Are structural calculations included?+
No, not in the building regulations fee. They are a separate service from £745, prepared by a named, insured engineer, or you can use your own engineer; either way we draw the beams and padstones onto the set so your builder has everything to price and build. Our all-inclusive packages include them.
Can you submit to Building Control for me?+
Yes, we prepare and submit the Full Plans package and respond to any Building Control queries.
Do I need planning permission for an extension in Southwark?+
It depends on the area. On Victorian terraces in Camberwell and Peckham a single-storey rear or side-return extension can fall within permitted development, but in the conservation areas across Camberwell, Dulwich, Bermondsey and Bankside, side extensions, dormers and other roof enlargements, rear extensions over one storey and cladding are not permitted development. We check your address against the designations first and can confirm permitted development with a Lawful Development Certificate where it qualifies.
What is the Dulwich Estate scheme of management?+
It is a distinctive Southwark consideration: many properties on the Dulwich Estate need Dulwich Estate consent in parallel with planning permission, similar in effect to a covenant. It is separate from the council's decision, so both must be satisfied. We flag whether the Estate scheme applies to your property before drawing and design to its requirements as well as the council's.
Can you handle a warehouse or riverside conversion in Bermondsey or Bankside?+
Yes. Southwark's riverside quarters carry their own townscape and taller-building context, and conversions there are assessed against conservation and design control near the Thames. We prepare drawings that respond to that setting and the council's design expectations, confirming the constraints for your specific building before design begins.
How long does Southwark Council take to decide?+
Southwark has eight weeks starting the day after a valid application lands; extra time requires written agreement. Dulwich, conservation and riverside cases can involve further consultation.
How much do planning drawings cost in Southwark?+
We agree a fixed fee before we start, taken from our published price list, with free redraws until Southwark approves. A Camberwell terrace extension and a Dulwich Estate application differ in the evidence required, so we quote once we have seen your address and project rather than by the hour.
