Housing Stock by Area
What kind of houses does Croydon have?
Croydon is London's largest borough by population, and its housing stock spans more building eras than almost anywhere else in London, from Victorian villas to 1960s tower blocks. Census figures put the mix at roughly 32.7% terraced, 32% flats, 21.8% semi-detached and 13.5% detached housing.
- Upper Norwood and Crystal Palace ward (SE19): large Victorian villas, many dating from when the area developed around the original Crystal Palace exhibition building on the ridge above.
- Thornton Heath and Selhurst (CR7, SE25): dense Victorian and Edwardian terraces, similar in age and construction to streets found across much of inner South London.
- Purley, Coulsdon and Sanderstead (CR5, CR8): 1930s semi-detached and detached suburbia built on the chalk downland of the North Downs, a genuinely different ground type to most of the borough.
- Croydon town centre (CR0): a mix of Victorian terraces around The Waldrons and Addiscombe, alongside the 1960s tower blocks that gave central Croydon its high-rise skyline during a major post-war rebuilding programme.
- New Addington and Forestdale (CR0): post-war and later council-built estates on the eastern edge of the borough, a different housing type again to the Victorian and interwar streets nearer the centre.
Common problems we see in Croydon properties
Croydon's ground conditions and flood risk vary more across the borough than in most of London, so we treat each area on its own terms rather than using one standard approach.
- Standard London Clay shrinkage in the town centre and north: Thornton Heath, Selhurst, South Norwood and Upper Norwood sit on London Clay with the usual seasonal shrink-swell pattern found across most of London.
- Chalk downland ground conditions in the south: Purley, Coulsdon and Sanderstead sit on the North Downs chalk escarpment, an area with a long history of chalk and lime quarrying. Foundation and basement work here needs different ground investigation to a standard clay-based site further north in the borough.
- Flood risk near the River Wandle and Norbury Brook: stretches of the Wandle, including through Wandle Park, sit in the functional floodplain, and the culverted Norbury Brook runs from Thornton Heath through to Tooting. Surface water flooding has also been recorded at the Purley Cross roundabout, along Brighton Road, and near Kenley station, Hamsey Green, Purley Oaks Road, Norbury and Thornton Heath.
- Dense terracing and party walls: Thornton Heath, Selhurst and South Norwood's Victorian and Edwardian terraces sit close together, so most rear extensions and loft conversions fall within 3 metres of next door, triggering the Party Wall etc. Act 1996.

What to check before starting building work in this borough.
London Borough of Croydon (Croydon Council)

Planning permission and conservation areas in Croydon
Croydon has 21 conservation areas, and the council is currently reviewing a further 9 areas for possible designation as part of a wider drive to protect the borough's architectural character. One of the borough's oldest is The Waldrons, designated in 1973 around a crescent of 19 Classical-style Victorian villas built from 1850 onwards, which gained an Article 4 Direction in January 2016 covering hard surfacing, gates, fences and boundary walls specifically. Other conservation areas include Chatsworth Road and Kenley Aerodrome, both also carrying householder Article 4 Directions that remove standard permitted development rights.
Croydon does not have a single borough-wide Article 4 Direction, so most standard rear extensions and loft conversions outside a conservation area keep normal permitted development rights, provided they meet national size and height limits. Before planning any external work in Croydon, check your address on Croydon Council's planning pages to confirm your conservation area status and whether a specific Article 4 Direction applies.
Realistic planning timescales
Croydon Council targets an 8-week determination period for householder applications, in line with the national standard, though this can run longer during busy periods. We build a realistic timeline into every Croydon quote rather than promising the statutory minimum.
What normally needs planning permission in Croydon
- Hard surfacing, gates, fences and boundary walls within The Waldrons conservation area
- External alterations affecting the appearance of a house inside Chatsworth Road, Kenley Aerodrome or other Article 4 areas
- Works to a tree protected by a Tree Preservation Order, or any tree inside a conservation area
- Any work affecting a Listed Building
What usually doesn't
- Standard single-storey rear extensions outside a conservation area, within normal permitted development size limits
- Internal, non-structural work: new kitchen or bathroom in the same footprint, redecoration
- Like-for-like repairs outside Article 4 areas: matching roof materials, identical window replacements, repointing
Services We Provide Across Croydon
Crystal Palace ward's Victorian villas need kitchen extensions that respect original bay windows and high ceilings, not boxy add-ons.
Coulsdon and Purley's 1930s semis sit on chalk downland, extensions there need different ground investigation to clay streets nearer town.
Thornton Heath and Selhurst's Edwardian terraces typically have one bathroom, layouts we reconfigure into proper family bathrooms.
Streets near the Norbury Brook have a real surface water flooding history, so drainage design there gets extra care, not a standard layout.
The Waldrons' Victorian villas need render and stucco repairs that match their 1850s original finish across this conservation area.
Why Croydon Homeowners Choose Soraiz Builders
Soraiz Builders & Services Ltd was founded in 2019 by Shamraiz Hussain and has completed 250+ projects across all 32 London boroughs. On a Croydon job, that means checking conservation area and Article 4 status against all 21 designated areas, and factoring in the borough's genuinely different ground conditions, from standard London Clay in the town centre and north to North Downs chalk in Coulsdon and Purley, rather than applying one standard approach borough-wide. We also work around Croydon's town centre tram loop and Surrey Street Market's Monday-to-Saturday trading hours when scheduling deliveries right in the centre, rather than treating every street the same.

Frequently Asked Questions
Answers to the questions homeowners in this area ask most.
Do I need planning permission for an extension in Croydon?
It depends on the property. Croydon doesn't have a borough-wide Article 4 Direction, so most single-storey rear extensions outside a conservation area keep normal permitted development rights within national size limits. Inside a conservation area with its own Article 4 Direction, such as The Waldrons or Chatsworth Road, more work needs full planning permission. We check your exact status before recommending a route.
Is my street in a Croydon conservation area?
Croydon has 21 conservation areas, including The Waldrons, Chatsworth Road, Kenley Aerodrome and several more, with a further 9 areas currently under review for possible designation. Check your exact address on Croydon Council's planning pages, or ask us to check it as part of a free quote.
Why does ground condition matter more in Coulsdon and Purley than in central Croydon?
Coulsdon, Purley and Sanderstead sit on North Downs chalk downland rather than the standard London Clay found through Thornton Heath, Selhurst and the town centre. The area has a real history of chalk and lime quarrying, so foundation and basement work there needs proper ground investigation rather than assuming standard clay conditions apply.
What's different about extending a Victorian villa in Crystal Palace ward compared to a 1930s semi in Coulsdon?
Victorian villas in Crystal Palace ward and Upper Norwood sit on standard London Clay and follow familiar shrink-swell patterns. 1930s semis in Coulsdon and Purley sit on chalk downland instead, which changes the foundation and ground investigation approach. We treat these as genuinely different jobs rather than using one method borough-wide.
Do I need a Party Wall Agreement for building work in Croydon?
Very likely in the borough's denser terraced streets. Thornton Heath, Selhurst and South Norwood's Victorian and Edwardian terraces sit close together, so most rear extensions or loft conversions fall within 3 metres of a neighbouring property. Notices need serving at least two months before work starts, and we handle this as part of the project.
Which parts of Croydon do you cover?
We cover the full London Borough of Croydon, including Thornton Heath, Selhurst, South Norwood, Addiscombe, Shirley, South Croydon, Sanderstead, Selsdon, Coulsdon, Purley, Kenley and New Addington, postcodes CR0, CR2, CR5, CR7, CR8 and SE25.
Is my Croydon property at flood risk, and does that affect building work?
Parts of the borough near the River Wandle, including through Wandle Park, sit in the functional floodplain, and the culverted Norbury Brook runs from Thornton Heath through to Tooting. Surface water flooding has also been recorded at spots including the Purley Cross roundabout and along Brighton Road. We check flood risk at quote stage for any property near these watercourses.
How long does planning permission actually take in Croydon?
Croydon Council targets 8 weeks to determine a standard householder application, in line with the national standard, though busy periods can push that longer. We build a realistic timeline into every quote rather than promising the statutory minimum and leaving you to find out otherwise.
