Builders in Greenwich: Conservation Area & Progress Estate Specialists in SE3, SE7, SE9 & SE18
Soraiz Builders carries out extensions, renovations and full-trade building work across Greenwich, from the Georgian and Victorian terraces of the town centre and Blackheath to the Edwardian streets of Charlton and Woolwich and the 1930s semis of Eltham. The clay formations beneath Woolwich and Charlton are significant enough to lend their own name to a layer of London's geology, the Woolwich and Reading Beds, exposed today at Gilbert's Pit in Charlton. Getting the ground right matters as much as the planning route here. Call Shamraiz Hussain's team today for a written quote within 2 hours.

Housing Stock by Area
What kind of houses does Greenwich have?
Royal Greenwich runs from the Thames at the Greenwich Peninsula and Woolwich in the north, through Charlton and Blackheath, down to Eltham, Kidbrooke and New Eltham in the south, and its housing stock reflects one of the highest concentrations of Victorian and Edwardian domestic architecture in London.
- Greenwich town centre and Ashburnham (SE10): Georgian and Victorian terraces around the Maritime Greenwich UNESCO World Heritage Site, with charming cottages east of the park.
- Blackheath and Blackheath Park (SE3): Georgian and Victorian villas among the borough's highest-value housing stock, several individually listed.
- Charlton, Plumstead and Woolwich (SE7, SE18): long streets of Victorian and Edwardian terraces built for the workforce of the Royal Arsenal and the naval dockyard, among the borough's most extensive terraced stock.
- Well Hall and Eltham (SE9): the Progress Estate, a 1915 estate of 1,298 houses built for senior Royal Arsenal munitions workers, no two houses alike, alongside the wider Edwardian and interwar suburbs of Eltham itself.
- Kidbrooke and New Eltham (SE9, SE3): 1930s semi-detached suburbia alongside significant post-war and more recent estate regeneration.
Common problems we see in Greenwich properties
Greenwich's ground, its planning regime and its relationship with the tidal Thames all vary enough across the borough that we treat each address on its own terms.
- The Woolwich and Reading Beds: the clay and shelly sand formations beneath Woolwich and Charlton are significant enough in the study of London's geology to lend their own name to a nationally recognised geological layer, the Lambeth Group's Woolwich and Reading Beds, exposed today at Gilbert's Pit in Charlton. Foundation and basement design in this part of the borough needs proper ground investigation rather than a standard London Clay assumption.
- Tidal flood risk on the Peninsula and riverside: the Greenwich Peninsula, Charlton Riverside and Woolwich sit in Flood Zone 3, protected by the Thames Barrier and tidal walls to a very high standard, but ground-floor and lower-ground work here still needs flood-resilient detailing given the residual risk from a breach.
- Dense Victorian terracing and party walls: Charlton, Plumstead and Woolwich's terraces sit close enough together that most rear extensions and loft conversions fall within 3 metres of a neighbouring property, triggering the Party Wall etc. Act 1996.
- The Progress Estate's Article 4 Direction: all 1,298 houses on this 1915 conservation estate in Well Hall have carried an Article 4 Direction since 1973, restricting front and side elevation changes, roofs, windows and doors on every single property, regardless of individual ownership.

Working around Greenwich's parking and access
Royal Greenwich operates Controlled Parking Zones by area, including East Greenwich, which runs Monday to Sunday from 9am to 6:30pm with a base resident permit cost of £106 a year. A skip licence costs £74, but only an approved skip hire operator on the council's own list can apply for it, and a skip placed in certain parking bays is charged separately by the day through Parking Services. We arrange builder's parking permits and skip licences through the correct channel in advance so materials and skips don't sit waiting on day one.

Planning permission and conservation areas in Greenwich
Royal Greenwich has 23 conservation areas, including Blackheath, Blackheath Park, Charlton Village, Eltham Palace, Royal Arsenal Woolwich, Well Hall Pleasaunce and Woolwich Common among others. Article 4 Directions apply within several of these, including Ashburnham Triangle, West Greenwich, East Greenwich, Rectory Field, the Shrewsbury Park Estate and the Progress Estate, removing permitted development rights for windows, doors, roofing materials and other external changes.
Standard single-storey rear extensions and loft conversions outside a conservation area and outside any Article 4 property can still keep permitted development rights, provided they meet national size and height limits. Before planning any external work in Greenwich, check your address against the council's conservation area maps and Article 4 register.
The Progress Estate: a rare case of universal coverage
The Progress Estate in Well Hall was designated a conservation area in 1971, with virtually no demolitions since the estate was built in 1915, and gained an Article 4 Direction in 1973 covering all 1,298 houses as they began selling into individual ownership. The direction restricts changes to front and side elevations, roofs, windows and doors across every property on the estate, a level of universal coverage that is unusual even among conservation areas.
Realistic planning timescales
Greenwich Council targets an 8-week determination period for householder applications, in line with the national standard, but a realistic timeline from initial instruction to final decision runs 12 to 16 weeks, and pre-application advice typically takes a further 4 to 6 weeks. The borough's householder approval rate, 77.6 percent over the year to Q1 2026, sits below the London average of 85.6 percent, so getting the application right first time, rather than relying on appeal, matters more here than in many boroughs. We build this realistic timeline and a properly prepared application into every Greenwich quote.

Frequently Asked Questions
Answers to the questions homeowners in this area ask most.
Do I need planning permission for a house extension in Greenwich?
It depends on the address. Standard single-storey rear extensions outside a conservation area and within national permitted development size limits usually don't need permission. Inside one of Greenwich's 23 conservation areas, on an Article 4 property, or anywhere on the Progress Estate, a full application is normally required. We check your specific address before any design work starts.
How many conservation areas does Greenwich have?
Royal Greenwich has 23 conservation areas, including Blackheath, Charlton Village, Eltham Palace, Royal Arsenal Woolwich and the Progress Estate. Several also carry an Article 4 Direction removing further permitted development rights on top of standard conservation area controls.
What is the Progress Estate and why does it have special planning rules?
The Progress Estate is a 1915 housing estate in Well Hall, Eltham, built for senior workers at the Royal Arsenal munitions factories. Its 1,298 houses were designated a conservation area in 1971, and in 1973 an Article 4 Direction was applied to all of them, restricting changes to front and side elevations, roofs, windows and doors regardless of who owns each individual house.
Is Greenwich at risk of flooding?
Parts of it, yes. The Greenwich Peninsula, Charlton Riverside and Woolwich sit in Flood Zone 3 and would flood at high tide without the Thames Barrier and tidal defences, which currently protect the borough to a very high standard. The Ravensbourne, Quaggy and Deptford Creek affect the western edge, and surface water flooding is recorded in Eltham, Kidbrooke, Plumstead and Abbey Wood.
How much does a house extension cost in Greenwich?
A single-storey rear extension typically costs £3,200 to £4,500 per square metre at a mid specification, with roughly 15 percent on top for projects inside a conservation area. A dormer loft conversion typically costs £45,000 to £65,000, and a mansard conversion £70,000 to £110,000.
How long does planning permission take in Greenwich?
The statutory target is 8 weeks, but a realistic timeline from initial instruction to final decision runs 12 to 16 weeks, and pre-application advice typically takes a further 4 to 6 weeks. Greenwich's householder approval rate, 77.6 percent, also runs below the London average of 85.6 percent, so a well-prepared application matters more here than in many boroughs.
Do I need a Party Wall Agreement for building work in Greenwich?
Often, yes, in the more terraced parts of the borough. Charlton, Plumstead and Woolwich's Victorian and Edwardian terraces are close enough together that a rear extension or loft conversion can fall within 3 metres of a neighbouring property, triggering the Party Wall etc. Act 1996. Notices need serving at least two months before work starts, and we handle this as part of the project.
Which parts of Greenwich do you cover?
We cover the full Royal Borough of Greenwich, including Greenwich town centre, Blackheath, Charlton, Woolwich, Plumstead, Eltham, Kidbrooke and New Eltham, across postcodes SE3, SE7, SE9, SE10 and SE18.
Why is the ground in Woolwich and Charlton different from the rest of London?
The clay and shelly sand beneath this part of the borough are distinctive enough to have given their name to a recognised geological layer, the Woolwich and Reading Beds, part of the wider Lambeth Group. They're exposed today at Gilbert's Pit in Charlton, and foundation or basement work here needs ground investigation specific to these formations rather than a standard London Clay assumption.
Is a loft conversion worth it in Blackheath or Eltham?
Generally yes. Blackheath's Georgian and Victorian villas and Eltham's Edwardian and 1930s stock both suit dormer or mansard conversions well, typically adding a bedroom and bathroom worth more than the £45,000 to £110,000 build cost in areas where property values are already high, particularly around Blackheath.
Can I change the windows on my house on the Progress Estate?
Not without planning permission. The Article 4 Direction covering all 1,298 houses on the Progress Estate since 1973 removes the usual permitted development rights for window and door replacements, along with roofs and front and side elevations, so even a like-for-like change normally needs an application first.
Why does Greenwich have a lower planning approval rate than other boroughs?
Greenwich's householder approval rate of 77.6 percent, against a London average of 85.6 percent, reflects the borough's dense conservation coverage and the universal Article 4 controls on estates like the Progress Estate. Getting pre-application advice and a well-prepared submission matters more here than in boroughs with higher approval rates.
Is Maritime Greenwich a UNESCO World Heritage Site and does that affect building work?
Yes. Maritime Greenwich, comprising the historic town centre, Greenwich Park and the Old Royal Naval College, was inscribed as a UNESCO World Heritage Site in 1997. Properties inside or near the site typically sit within a conservation area with correspondingly strict controls on external alterations.
