About Anerley
Anerley is where we are based — our office is on Limes Avenue, SE20. Being local means we know every street, every property type, and every planning quirk in the area. The Victorian terraces along Anerley Road and the Edwardian semis around Anerley Hill are properties we have worked on many times, and we can often give accurate estimates based on similar projects we have completed on the same street.

Popular Services in Anerley
Kitchen extensions and side return conversions are the most popular projects in Anerley, followed by loft conversions on the Edwardian semis that have good roof height for dormer conversions. We also handle a lot of damp proofing work — the older properties in SE20, particularly those on the lower slopes near Penge, are prone to rising damp where original damp-proof courses have deteriorated. End-of-tenancy painting is common too, as Anerley has a strong rental market with many buy-to-let properties.
Planning & Building Control in Anerley
Anerley falls under Bromley Council planning. The area is not within a conservation zone, which means permitted development rights are generally available for standard rear extensions, loft conversions, and garage conversions. Bromley Council's planning portal is straightforward to use, and we submit Lawful Development Certificates for all projects to give homeowners written confirmation that their extension is permitted.
Anerley Property Insights
Anerley properties built between 1870 and 1910 typically have solid 9-inch brick walls, timber floors, and slate roofs. Many have original lime plaster internally, which is breathable and should be retained where possible — replacing it with modern gypsum plaster can actually trap moisture and worsen damp problems. The ground conditions in SE20 are mixed clay and gravel, and foundation depths for extensions typically range from 1.0 to 1.3 metres.
Common Projects in Anerley
Full house renovation on a Victorian terrace
The most common big project in Anerley. New owners take possession of a tired late-Victorian terrace, often previously let, and want the whole property brought up to modern standards. Scope includes rewiring to BS 7671, replumbing, knocking through the ground floor for an open-plan kitchen-diner, new kitchen and bathrooms, plastering throughout, and full redecoration. Typical budget from £60,000 depending on size and specification. Programme is 14-20 weeks with a single project manager, fixed-price contract, and photo updates throughout the build.
Single-storey rear kitchen extension
Most Anerley terraces have a dark galley kitchen at the back that doesn't suit modern family life. We open the rear wall, add 4-5 metres of single-storey extension with bifold doors or a roof lantern, and create an open-plan kitchen-diner with direct garden access. Permitted development covers most of these (3 metres for terraced, 4 for semi-detached) without a planning application. Typical cost from £45,000 including foundations, steelwork, glazing, electrics, plumbing, and finishes. Build time 10-14 weeks.
Loft conversion on an Edwardian semi
The Edwardian semis in Anerley have generous roof height and most suit a hip-to-gable conversion that creates a full-size master bedroom with en-suite. The conversion adds a fourth or fifth bedroom and typically 25-35 square metres of usable space. Cost is from £40,000 including dormer or hip-to-gable structural work, staircase, en-suite plumbing, electrics, plastering, and decoration. Build time 8-12 weeks. Party wall agreements with both neighbours take 4-8 weeks and need to be served before work starts.
Damp proofing on a pre-1910 property
Particularly common on the lower-lying streets towards Penge where groundwater accumulates. Original slate damp-proof courses have failed after 120+ years, and the ground-floor walls show a tide mark of rising damp at about a metre above floor level. We diagnose first (rising, penetrating, or condensation), inject a silicone-based DPC cream into the mortar course, allow 4-6 weeks for the wall to dry, then replaster with salt-resistant render. Cost from £2,500 including replastering. Treatment is guaranteed for 20 years.

Frequently Asked Questions
- Do I need planning permission for an extension in Anerley?
- Most single-storey rear extensions in Anerley fall under permitted development and don't need a planning application. Limits are 3 metres from the rear wall for terraced houses and 4 metres for semi-detached or detached, with eaves height up to 3 metres and overall height up to 4 metres. Anerley is not in a conservation area, which keeps the rules straightforward. We submit a Lawful Development Certificate (£129) to Bromley Council for written confirmation, which protects the property at sale time. Larger projects need a full planning application, and we handle that as part of the project.
- Why does it matter that your office is in Anerley?
- Practical reasons. We can be at any Anerley property in five minutes for a survey, mid-job decisions, or post-completion snags. Most quotes go out within 48 hours of the visit. If something goes wrong on a project, we drop in the same day rather than booking a callout in three weeks. We've also done enough work in SE20 to know which streets have clay subsidence risks, which terraces share old soil stacks worth replacing during renovation, and which streets have planning quirks. Local knowledge isn't a marketing line — it changes how we price and schedule work.
- What's a typical budget for renovating an Anerley terrace?
- A full renovation of a typical 3-bedroom Anerley Victorian terrace lands at from £60,000 depending on what's included. Lower end covers rewire, replumb, new kitchen and bathroom, plastering, decoration. Higher end adds a single-storey rear extension with bifold doors, loft conversion, premium fixtures, and structural work to open up the ground floor. We provide a fixed-price contract after a site visit so the budget is firm before any work starts. Smaller projects (single-room renovations, bathroom refits, repaints) start around £4,000.
- Do you work on Anerley conversion flats and HMOs?
- Yes. Anerley has a high proportion of Victorian houses split into 2-3 conversion flats and a number of HMOs around the streets near Anerley station. We handle individual flat renovations and end-of-tenancy turnarounds, plus communal area repaints when the freeholder coordinates a single repaint across all flats. For HMOs, we paint individual rooms between tenancies rather than waiting for the whole property to be empty, which keeps the landlord earning rent throughout. Typical HMO room turnaround £400-£700 depending on size and condition.
