Introduction
SE15 Peckham and Nunhead sits within the jurisdiction of the London Borough of Southwark. The area is characterised by Victorian and Edwardian terraced housing, Nunhead Victorian cottages, offering a varied range of residential improvement opportunities. Whether you are planning a rear kitchen extension, a loft conversion to add a bedroom, or a full house reconfiguration, Crown Architecture brings the local planning knowledge and design expertise to deliver your project efficiently.
We have an established track record working on properties in Peckham, Nunhead, Rye Lane area, and our familiarity with the London Borough of Southwark planning team means we can advise accurately on what is achievable — and how to achieve it — before you commit to a design direction.
The area’s housing stock presents both opportunity and design responsibility. Working within the character of the existing streetscene, respecting conservation area constraints where they exist, and producing architecture that enhances the built environment — these principles underpin every project we deliver in SE15.
Transport connections across SE15 are strong — Peckham Rye (Overground/National Rail), Queens Road Peckham (Overground) — making this an attractive area for homeowners who choose to extend and improve rather than move. We see this pattern consistently: families who value their location invest in their homes, and Crown Architecture provides the professional architecture service to make those investments count.

Frequently Asked Questions — Architects in SE15 Peckham and Nunhead
Q1: Do I need planning permission for a rear extension in SE15?
A: If your property is not in a conservation area and retains permitted development rights, a single-storey rear extension up to 3m deep (attached) or 4m deep (detached) typically does not require planning permission. Extensions beyond these depths, double-storey additions, or works in conservation areas require a full planning application to the London Borough of Southwark. We advise on your specific address.
Q2: Can I convert my loft in SE15 Peckham and Nunhead?
A: Yes — most properties in SE15 are suitable for loft conversions. A rear dormer typically does not require planning permission under Class B permitted development, unless in a conservation area. Hip-to-gable conversions on semi-detached houses do require planning permission as they alter the roofline. We carry out a free feasibility check for your specific property.
Q3: How long does a planning application take with London Borough of Southwark?
A: The statutory target is 8 weeks from valid submission for minor residential applications. In practice, expect 9-12 weeks. Pre-application advice from the council can reduce the risk of refusal and is worth considering for complex or conservation area projects.
Q4: What are the conservation areas in SE15?
A: The main conservation areas in SE15 include Nunhead Conservation Area, Southampton Way Conservation Area, East Peckham area. Properties within or adjacent to these areas face stricter design guidance. We check your address and provide specific advice before any design work begins.
Q5: How much does an architect cost for a house extension in SE15?
A: Our fees for a standard rear extension (surveys, planning drawings, building regulations) start from £3,500 + VAT. More complex projects — double-storey additions, conservation area applications, listed building consent — are quoted individually. We offer a free initial consultation.
Q6: What is a side-return extension and can I do one in SE15?
A: A side-return extension fills the narrow gap alongside a Victorian or Edwardian terraced house to create a wider ground floor. Most side-return extensions in SE15 qualify as permitted development (Class A) and do not require planning permission, unless in a conservation area. The result is typically a significantly larger kitchen-diner.
Q7: Do I need building regulations as well as planning permission?
A: Yes — planning permission and building regulations are separate approvals. Planning permission covers the appearance and principle of the development; building regulations cover structural safety, insulation, fire escape, and energy efficiency. We prepare both sets of drawings and submit both applications.
Q8: Can Crown Architecture handle the whole project from design to construction?
A: We provide architectural services from initial feasibility through to planning permission and building regulations approval. We can also prepare tender documentation for contractors and provide contract administration during construction. We are a full-service architectural practice.
