About Streatham
Streatham stretches along one of the longest high streets in London, with a diverse mix of Edwardian terraces, Victorian semis, and 1930s houses across Streatham Hill, Streatham Common, and Streatham Vale. The area offers good-sized family homes at lower prices than Balham and Clapham, and many homeowners are investing in extensions and renovations to create the space they need without moving.

Popular Services in Streatham
Loft conversions are the standout project in Streatham, particularly on the Edwardian terraces and 1930s houses that have good roof height for dormer conversions. Kitchen extensions are also popular on the Victorian and Edwardian terraces, with most clients extending 3-5 metres to create an open-plan kitchen-diner. Full property renovation is common for buyers purchasing on Streatham Hill and Leigham Vale, where unrenovated period houses can be turned around with a full refurbishment.
Planning & Building Control in Streatham
Streatham falls under Lambeth Council. The Streatham Common and Streatham Hill conservation areas have design requirements for visible alterations. Lambeth Council operates a straightforward permitted development process for standard rear extensions and loft conversions. Article 4 directions apply in some streets, restricting certain permitted development rights — we verify this for every property. Lambeth has a planning duty officer service that is useful for quick queries about specific sites.
Streatham Property Insights
Streatham has a broad mix of property ages and construction types. The Edwardian terraces typically have solid brick walls and slate roofs, while the 1930s houses often have cavity walls and concrete tile roofs. The variation in building construction means renovation approaches differ street by street. The clay subsoil across SW16 is consistent, requiring standard foundation depths for extensions. Streatham Common sits on slightly higher ground with better drainage than the surrounding streets.
Common Projects in Streatham
Loft conversion on an Edwardian terrace or 1930s semi
The standout Streatham project. The Edwardian terraces along Streatham Hill and the 1930s houses around Streatham Common have good roof height for dormer or hip-to-gable conversions. Hip-to-gable on a 1930s semi typically creates a master bedroom with en-suite plus space for a second bedroom or home office. Cost is from £55,000 including structure, staircase, en-suite plumbing, electrics, plastering, and decoration. Build time 10-14 weeks. Lambeth Council's permitted development process is straightforward, though the Streatham Common and Streatham Hill conservation areas have additional design requirements.
Single-storey rear kitchen extension
Common on Streatham's Victorian and Edwardian terraces. Rear extensions of 3-5 metres create open-plan kitchen-diners with garden access. Cost is from £45,000 including structural steelwork, foundations on Streatham clay (typically 1.0-1.2 metres), glazing, electrics, plumbing, and finishes. Build time 10-14 weeks. The 1930s houses around Streatham Common typically have cavity walls (unlike earlier Edwardian properties), which makes insulation tie-in straightforward during the extension. Lambeth's permitted development process covers the standard 3-metre rear extension on terraces and 4 metres on semis.
Full property renovation on Streatham Hill
Streatham attracts buyers picking up unrenovated period houses on Streatham Hill and Leigham Vale at prices below neighbouring Balham and Clapham. Full refurbishments typically include rewiring to BS 7671, replumbing, knocking through the ground floor, new kitchen and bathrooms, plastering, and complete decoration. Cost is from £75,000 depending on size and specification. Build time 14-22 weeks with one team. Original features (cornicing, ceiling roses, parquet flooring) are protected during structural work and add £15,000-£30,000 to property value at sale time.
Garage conversion on a 1930s house
Common on the 1930s houses around Streatham Common and Streatham Vale that have integral or attached garages. Conversion gives a usable room of 12-16 square metres for £15,000-£22,000, suitable for a home office, extra bedroom, or playroom. Build time 4-8 weeks. The concrete raft foundations under most 1930s garages are solid enough to support the conversion without additional foundation work, though we always check at the survey. Some 1930s properties have planning conditions requiring parking provision — these need a variation of condition application before conversion can proceed.

Frequently Asked Questions
- How does the variation in Streatham property types affect renovation approach?
- Different ages need different approaches. Edwardian terraces (most of central Streatham) have solid brick walls and original lime plaster — extensions need internal wall insulation rather than cavity fill, and breathable mineral paint is the right choice for original walls. 1930s houses (around Streatham Common and Streatham Vale) have cavity walls — extensions tie new insulation into the existing cavity using bonded bead, which is more efficient than internal lining. Loft conversions on Edwardian properties typically use cut-rafter construction; 1930s properties may have trussed roofs that need structural modification. We assess each property individually at the survey.
- Are the Streatham Common conservation areas restrictive?
- Moderately. The Streatham Common conservation area covers properties around the Common itself; the Streatham Hill conservation area covers parts of the upper hill streets. Both impose specific requirements on visible alterations — front-facing changes need sympathetic design, dormer proportions are restricted, render colour and front door changes need consideration. Rear extensions are usually fine because they're not visible from the street. Lambeth Council can act on retrospective unauthorised changes. Article 4 directions in some streets restrict additional permitted development rights — we verify the planning status of each property before quoting.
- Why is Streatham good value for renovation work?
- Property prices on Streatham Hill and Leigham Vale are typically 20-30% below equivalent properties in Balham or Clapham, but the housing stock and renovation potential are similar. The same renovation budget gets a larger property in Streatham, and the property value uplift from a well-executed kitchen extension or loft conversion is similar in absolute terms. Lambeth Council planning fees and Building Control fees are standard, and trade rates are at the lower end for South West London. Returns on renovation work in Streatham typically come in at 1.3-1.5x cost in property value uplift.
- Do I need permission to convert my Streatham garage?
- Usually no, but check the planning history. Change of use from garage to habitable room is permitted development for most properties. If your house was built since the 1980s the original consent may carry a condition requiring the garage to be retained for parking, which needs a variation of condition application before conversion. Most Streatham 1930s properties don't carry this restriction. We check the planning portal at the survey and confirm what's needed before any work starts. The Lawful Development Certificate route gives written confirmation from Lambeth Council for £129.
