Renovations in Streatham

Mansion blocks, Queen Anne semis and estate terraces

Lambeth’s documents for Streatham describe mansion blocks and apartment blocks along the High Road and Streatham Hill, Queen Anne-style semi-detached houses on ample plots in the Streatham Park and Garrads Road conservation area, and the long terraces of flats and houses on the Leigham Court Estate. Plan your house, flat or bathroom from what is actually there and from the consents that apply at that exact address.

01 Queen Anne, Arts and Crafts and Victorian houses

House refurbishment in Streatham

Streatham’s houses include E. J. Tarver’s Queen Anne-style houses in Telford Park, laid out between 1878 and 1882, the mostly detached and semi-detached Streatham Lodge houses, whose 1910s and 1920s examples draw on Arts and Crafts, and the smart detached houses of Leigham Court Road (South). Lambeth’s 2023 Design Guide generally supports dormers at the rear and resists them on front slopes where they are not characteristic, and Article 4 directions cover the Leigham Court Estate and part of Streatham Lodge.

  • Address checked against the conservation area map and any Article 4 schedule
  • Dormer and roof plans read against the Design Guide
  • Original sashes, porches and boundaries recorded

02 Mansion blocks, conversions and estate flats

Flat renovation in Streatham

Flats feature in several of Lambeth’s Streatham documents. The High Road statement records purpose-built apartment blocks of the late Victorian, Edwardian and inter-war eras, the Streatham Common and Streatham Park documents record many large houses divided into flats after the war, and the Leigham Court Estate was built as maisonettes, flats and houses. Begin with the lease, since LEASE points out that alterations can need the freeholder’s permission even once planning permission or Building Regulations approval is granted.

  • Lease checked for the freeholder’s say on alterations
  • Stack and floor shared with neighbours traced
  • Window pattern matched to the whole block

03 Bathrooms in houses, conversions and blocks

Bathroom renovation in Streatham

A standalone bathroom renovation is welcome, whether it is a family bathroom in a Telford Park house, an en-suite in a Streatham Lodge semi or the only bathroom of a flat in a converted Streatham Park house or a mansion block. GOV.UK says installing a bathroom that involves plumbing can need Building Regulations approval, and in a flat the stack and extract route may serve the homes above and below.

  • Path of the waste pipe to the building’s stack plotted
  • Extract outlet agreed with the managing agent
  • Joists under the new bathroom checked before tiles

Local knowledge with a purpose

Understand the building before changing it

Streatham here means the Lambeth neighbourhoods around Streatham High Road, Streatham Hill and Streatham Common, in the south of the borough. Lambeth has 62 conservation areas, and this page draws on the profiles, appraisals and statements of the nine in and around Streatham.

Streatham Common Conservation Area, first designated on 16 June 1994, lies on Lambeth’s southern boundary; the adjoining Norwood Grove is in Croydon. Its April 2017 appraisal describes an eclectic mix of historic housing round a historic open space, in stock, red and gault brick, with timber sliding sashes the usual 19th-century window. Leigham Court Road (South), designated in 1981 and wholly residential, adjoins it at its own south-west corner and has smart detached houses in large gardens; unusually, it takes in some front gardens but not the houses behind them.

The Streatham High Road and Streatham Hill area, first designated on 7 December 1999 with boundary changes in January 2024, has a busy town-centre character: shops and entertainment buildings beside churches and residential mansion blocks. Immediately east of the High Road, Sunnyhill Road has modest terraced and semi-detached Victorian brick cottages, and Leigham Court Road (North), designated in 2002, has villas widely spaced in ample grounds. The Leigham Court Estate, first designated on 18 February 1981, was built between 1889 and 1928 as long terraces of flats and houses on a grid.

On Lambeth’s south-western edge, the Streatham Park and Garrads Road area, designated as Garrads Road in 1969 and extended in 1999 and 2002, is roughly bounded by Garrads Road, Bedford Hill, Ockley Road and Rydal Road; its November 2023 statement describes leafy suburban development of 1880 to 1930, including large Queen Anne-style semi-detached houses on ample plots. Streatham Lodge, designated on 8 June 2009, centres on an estate of late 19th and early 20th-century houses in a mature suburban setting, and Telford Park, from 1994, covers houses laid out between 1878 and 1882.

The first local check

Lambeth, Wandsworth or Croydon: check the address

A Streatham address or an SW16 or SW2 postcode does not settle the council, a conservation boundary, a listing or the consent route. The Streatham Park and Garrads Road area sits on Lambeth’s boundary with Wandsworth and is contiguous with Wandsworth’s Tooting Bec conservation area, and Streatham Common is on the edge with Croydon. Lambeth’s own skip page asks applicants to confirm an address is in Lambeth first. Check the constraints tab on Lambeth’s planning database, the list entry, any Article 4 direction, the lease or title and the planning history.

Separate checks, one coordinated brief

Planning, listed buildings, building control and leases

One approval does not settle every requirement. Identify the applicable routes before ordering work, and record who will prepare submissions, arrange inspections and provide the relevant completion information.

Planning permission and householder rights

Which kinds of Streatham work call for a planning application?

Work confined to the interior is not development, GOV.UK’s guidance explains, so refitting rooms inside a Streatham house or flat seldom needs permission. Flats sit outside the Part 1 householder permitted development rights, which apply to houses. For a house, test each external item against those rights and against any Article 4 direction: Lambeth says permission is required for any work a direction identifies, and the Leigham Court Estate and part of Streatham Lodge have one. Lambeth’s Design Guide adds that most basement development needs planning permission.

Listing, Lambeth’s local heritage list and conservation areas

Does listing in Streatham reach the inside of a building?

Yes. Where a building is on the statutory list, work inside it that affects its character can need listed building consent, just as outside work can. Entries in Streatham include the Church of St Leonard, the Grade II* Church of the English Martyrs, Streatham Hill Theatre, the Grade II* villa formerly known as Park Hill, Leigham Lodge and the Church of St Margaret. Conservation areas are a separate control: Lambeth requires planning permission to demolish a building in one. Lambeth’s local heritage list adds no extra planning controls but is weighed when applications are assessed.

Building Regulations

Where does Building Regulations approval fit in a Streatham project?

Building Regulations approval is a regime of its own: Lambeth’s page says building work at home must meet minimum standards set by law, and LEASE treats it as distinct from both planning permission and a landlord’s permission. GOV.UK names installing a bathroom that involves plumbing as work that can need approval, and Lambeth’s Design Guide notes that replacement windows should be at least double glazed, with exemptions for listed buildings and buildings in conservation areas to preserve historic windows. Agree before work begins who submits the application.

Lambeth: building regulations · When Building Regulations approval is needed · Lambeth Design Guide SPD, Part 4: building alterations, extensions and retrofit · LEASE: alterations and home improvements

Freeholder consent for flats, notice for shared walls

Beyond Lambeth’s consents, which other agreements can Streatham work need?

For a flat in a mansion block, a converted house or the Leigham Court Estate, the lease decides whether the freeholder must approve alterations, and LEASE notes that this holds even with planning permission or Building Regulations approval in hand. The Party Wall procedure is separate and applies only where work is on or near a shared boundary or party wall, as it can be between the terraced cottages of Sunnyhill Road, and GOV.UK explains what notice neighbours are owed.

Designations 1969–2009

Nine conservation areas and their documents

Lambeth’s documents give these first designations: Garrads Road, 1969, renamed Streatham Park and Garrads Road in 1999; Sunnyhill Road, 2 April 1973, part of which moved to the High Road area in 1999; Leigham Court Estate, 18 February 1981; Leigham Court Road (South), 1981; Streatham Common, 16 June 1994; Telford Park, 9 September 1994; Streatham High Road and Streatham Hill, 7 December 1999; Leigham Court Road (North), 2002; and Streatham Lodge, 8 June 2009.

The documents vary in age. Leigham Court Road North and South have appraisals of September 2016, Streatham Common one of April 2017 and Sunnyhill Road one of May 2017; the Streatham Park and Garrads Road statement of November 2023 is a material planning consideration. Telford Park’s guidance is its 1994 designation report, Streatham Lodge’s 2009 designation report sets out the case for that area, and the High Road area has a conservation area statement.

Article 4: 1996 and 2010

Article 4 on the Leigham Court Estate and part of Streatham Lodge

The Leigham Court Estate direction is dated 22 October 1996 and was approved by the Secretary of State for the Environment on 18 November 1996. It takes away householder rights to enlarge or alter a house, add to or alter the roof, build a porch, lay hard surfaces and fit satellite antennas, plus rights over gates, fences and walls, means of access and exterior painting. The estate’s 2001 guidelines say that demolition under the direction includes removing chimney pots or stacks, windows, doors, fences or hedges.

Leigham Court Estate Article 4(1) direction, 1996 · Leigham Court Estate conservation guidelines, 2001

The Streatham Lodge direction was made on 21 June 2010, served on 23 July 2010 and confirmed on 18 October 2010, and covers only part of the conservation area: the houses its schedule names on nine streets, including Baldry Gardens, Braxted Park, Copley Park and Strathbrook Road. Where the work fronts what the notice calls a relevant location, it controls house alterations, roof slopes, porches, hard surfaces, gates, fences and walls, their demolition and exterior painting. Lambeth says permission is required for any work a direction identifies.

Elsewhere the documents recorded no direction at the time of writing: Streatham Common and Sunnyhill Road in 2017, the two Leigham Court Road areas in 2016 and Streatham Park and Garrads Road in 2023. The High Road and Telford Park documents do not say either way, so ask Lambeth for the current position on any address.

Local Plan 2021; Design Guide 2023

Lambeth’s adopted plan and design guidance

The Lambeth Local Plan 2021, adopted on 22 September 2021, covers 2020 to 2035, and under its Policy Q23 the council keeps a local heritage list. Lambeth has two borough-wide supplementary planning documents and one for a single area. Its Design Guide SPD was adopted on 8 August 2023: Part 4 guides alterations, extensions and retrofit, and Part 5 guides basement schemes. The Leigham Court Estate guidelines of 2001 are not among the current SPDs, so treat them as dated guidance.

Lambeth is preparing a new Local Plan. Its scoping consultation has closed and a Findings Report is to follow; no draft plan has been published, so the 2021 plan remains the one to apply.

Before sashes are ordered, a roof is opened or ground is dug, settle for the exact address which regimes apply, and keep them apart: planning permission, which Lambeth’s Design Guide says most basement development needs; any Article 4 direction, which on the Leigham Court Estate reaches windows, doors, boundaries and exterior painting, and, on part of Streatham Lodge, alterations, boundaries and painting that front what its notice calls a relevant location; listed building consent; conservation area controls, including permission to demolish; Building Regulations approval; any consent the lease requires; notice under the Party Wall Act for shared walls or digging close to a neighbour’s foundations; and notice to Lambeth six weeks ahead of work to a conservation-area tree, unless an exemption applies.

From retained details to shared services

Sashes, stacks, terraces, front gardens, basements and retrofit

Sashes and replacement windows

The Streatham Common appraisal records vertical timber sliding sashes as the predominant 19th-century window, and the 2023 Streatham Park statement calls the replacement of historic timber windows with uPVC a recurrent problem. Lambeth’s Design Guide asks that new windows match the originals where a terrace or group shares its window detailing, and notes that a flat’s windows are often identical to those of the whole building. On the Leigham Court Estate, the 2001 guidelines say window and door changes need permission under the Article 4 direction.

Shared stacks in blocks and divided houses

Streatham’s flats include purpose-built apartment blocks and large houses divided after the war, and at Park Hill the mansion and outbuildings were converted into homes in 2000. In any of these, a bathroom may share a stack and a ventilation route with the flats above and below, so trace both and read the lease before moving the room. GOV.UK lists plumbing for a new bathroom among the jobs that can need Building Regulations approval.

Streatham High Road and Streatham Hill conservation area statement · Streatham Common conservation area character appraisal, April 2017 · Streatham Park and Garrads Road conservation area statement, November 2023 · LEASE: alterations and home improvements · When Building Regulations approval is needed

Walls, floors and terraces

Before an internal wall or chimney breast is taken out, our own structural engineers check what it carries, and the work must meet the Building Regulations. In the long terraces of the Leigham Court Estate or the terraced cottages of Sunnyhill Road, work on a party wall can bring in the Party Wall Act. Where a flat sits over another home, plan the floor build-up for sound as well as structure, and agree access to the flat below with its owner and the managing agent.

Front gardens, hedges and hard surfaces

The Streatham Park statement says many front gardens there have been turned into car parks, to ill effect, against a setting of gardens, hedges and soft landscaping. Leigham Court Road (South) includes some front gardens in the conservation area precisely to protect trees and control boundary treatments. Lambeth says demolishing fences, gates and walls in a conservation area may need permission, and the Article 4 directions bring hard surfaces, gates, fences and walls under control on the Leigham Court Estate and, where the work fronts a relevant location, on part of Streatham Lodge.

Basements, gardens and trees

Lambeth’s Design Guide says most basement development needs planning permission and that, in a conservation area, associated demolition may need it too. Gardens matter here: the Streatham Common appraisal finds most homes with reasonably sized gardens of mature shrubs and trees. Unless an exemption applies, work to a conservation-area tree needs six weeks’ notice to Lambeth first, and doing it without notice is an offence; trees may also carry a Tree Preservation Order. Excavation close to a neighbour’s foundations may call for Party Wall notice.

Retrofit, glazing and roofs

Treat insulation, heating and ventilation as one design question rather than three separate purchases. Part 4 of Lambeth’s Design Guide covers alterations, extensions and retrofit: it notes that replacement windows should be at least double glazed, with exemptions for listed buildings and conservation areas to preserve historic windows, and that rooflights on heritage assets and in conservation areas should be small. Exterior painting is controlled on the Leigham Court Estate, and on part of Streatham Lodge where it fronts a relevant location, so check before painting brickwork.

A practical plan for the street and building

Working hours, deliveries and shared access

Skips, highway licences and parking suspensions

In Lambeth only skip companies can obtain skip licences, applying on the customer’s behalf, and the council asks them to confirm first that the address is in Lambeth, which matters at Streatham’s edges with Wandsworth and Croydon. The largest skip allowed is six yards; anything bigger counts as a container under a highways licence, which also covers scaffolding, hoarding, materials storage and cabins and is not granted until the fee and any deposit are paid. A standard parking suspension, including one for a skip, needs at least 10 working days’ notice.

Lambeth: apply for a skip licence · Lambeth: apply for a highways licence · Lambeth: highways licence application fees and deposits · Lambeth: parking suspension notice periods

Permitted hours, neighbours and occupation

Lambeth sets the hours: construction and building work may start at 8am and must stop by 6pm on weekdays and by 1pm on Saturdays, and Sundays and bank holidays are off limits. Plan the noisy stages inside those hours, tell neighbours and any managing agent the dates in writing, and in a mansion block or on the Leigham Court Estate agree deliveries and access with the building. Decide with your household whether to stay at home through the loudest work.

Lambeth: building noise and permitted hours

A clear scope before a price

Plan your renovation budget and quotation

Quotations compare properly only when they rest on one survey and one written scope. In Streatham, set the outside items, such as sashes, roof slopes, porches, front gardens and painting, apart from the rooms, and mark any that depend on a planning or Article 4 decision, the freeholder’s consent, a tree notice or a Party Wall notice.

Existing condition

Survey the house or flat as it stands and send every bidder the same drawings and photographs.

  • Ceiling heights recorded on measured drawings
  • State of sash windows, roof and front wall recorded
  • Exploratory openings agreed before pricing

Rooms, finishes and services

Write down, room by room, what is removed, what is installed and the finish you expect.

  • Make and model of each fitting recorded
  • Routes for waste, extract and the stack drawn
  • Your own supplied items named

Approvals and site arrangements

List each consent and licence the job depends on, with who obtains it and when.

  • Conservation area, Article 4 and listing checked
  • Timing of lease consent and neighbour notices
  • Skip, highways licence and suspension booked

Written allowances and sequence

Agree in writing how unseen work is allowed for, what is excluded and the order the trades follow.

  • Each provisional sum on its own line
  • VAT treatment shown
  • Building control completion certificate allowed for

There is no Streatham surcharge and no set Streatham programme; what the building needs and what you ask for decide cost and timing. Ask for VAT and professional fees, for example drawings or structural engineering, to be shown the same way in every quotation. If you want only a bathroom, it is standalone work with its own quotation, based on that room’s survey and its list of fittings.

From an idea to a workable scope

Prepare your brief and renovation budget

  1. Address and building type

    Send the full address with the house or flat number, because the Article 4 directions on the Leigham Court Estate and Streatham Lodge list named house numbers, and Lambeth’s own skip page asks for the address to be confirmed as being in Lambeth. Say whether the flat is in a mansion block, a converted house or the Leigham Court Estate, and add photographs of front, back, roof and rooms.

  2. Documents to share

    Useful papers include the lease or title register, earlier planning or Article 4 decisions, building control certificates and old drawings. For a flat, add who manages the building and any house rules it sets for works. Note anything already established, such as a Tree Preservation Order or a local heritage listing.

  3. What is settled and what is open

    Separate firm choices, such as a chosen bath or the rooms to repaint, from items waiting on the survey, our engineers, a tree notice or a decision from Lambeth. Each builder then prices the undecided items as one shared list of named allowances.

  4. Living with the work

    Tell us when you need the home back, which rooms must keep working and whether you will move out. Then settle in writing who handles each application: the skip, the highways licence, the parking suspension, any tree notice, Building Regulations approval and Party Wall notices.

Questions before you begin

Renovating in Streatham: practical answers

Do you take on a single bathroom by itself in Streatham?

Yes. A single bathroom is welcome as a standalone renovation in a Streatham house or flat, and nothing else in the home need change. The most useful first details are the floor level, the room below, the route the waste seems to take and the current ventilation, with rough measurements and a few photographs. In a mansion block or a converted house, mention who manages the building, since the stack and extract route may be shared.

Is my Streatham street inside one of Lambeth’s conservation areas?

Look the property up on Lambeth’s planning database, where a conservation area shows in the constraints tab. This page covers nine in and around Streatham, and three of them carry Leigham Court in their names: the Estate, Leigham Court Road (North) and Leigham Court Road (South), each with its own boundary. Leigham Court Road (South) even includes some front gardens without the houses behind them. At the Wandsworth and Croydon edges, confirm the council before anything else.

Do the Leigham Court and Streatham Lodge Article 4 directions, or listing, affect my home?

Article 4 directions cover the Leigham Court Estate and the scheduled houses of part of Streatham Lodge; the other documents recorded none when written, and the High Road and Telford Park documents do not say, so ask Lambeth. Listing goes building by building: Leigham Lodge and the Park Hill villa are listed, while Telford Park’s 1994 report says none of its houses is listed but values them as a group. For a listed building, consent may be needed for work inside too.

What applies to replacing sashes in Streatham, including on the Leigham Court Estate?

Survey them first. Timber sliding sashes were the usual 19th-century window by the Common, and the Streatham Park statement treats uPVC replacements as a recurrent problem. Lambeth’s Design Guide asks for new windows to match where a terrace or group shares its detailing, and observes that a flat’s windows are often the same across the whole building. Article 4 makes window changes on the Leigham Court Estate subject to permission, and the lease may require the landlord’s consent.

Who must agree before I refit the inside of my Streatham flat?

Start with the lease. LEASE explains that, under its terms, the freeholder may need to approve alterations, and that this applies even with planning permission or Building Regulations approval in place. Planning seldom comes into a refit kept inside the flat, because interior work is generally not development. Building Regulations approval can still apply to a bathroom with plumbing, and if the building is listed, consent can extend to internal work.

Which checks come before structural changes or a bathroom move in Streatham?

First, what the wall carries: our structural engineers check the loads, and the work must meet the Building Regulations. In the terraces of Sunnyhill Road or the Leigham Court Estate, work on the party wall can bring in the Party Wall Act. A moved bathroom still needs its waste to fall to the stack; in a mansion block or converted house that stack may be shared, so the lease and the managing agent come into it.

Is digging out a basement under a Streatham house an option?

It may be possible, but Lambeth’s Design Guide says most basement development needs planning permission, and in a conservation area associated demolition may need it too. Gardens add checks: Lambeth wants six weeks’ notice of work to a conservation-area tree unless an exemption applies, and some trees have preservation orders. If the dig comes near a neighbour’s foundations, the Party Wall Act may apply, and for a flat the lease may require the freeholder’s agreement.

Which days and times does Lambeth allow for building work in Streatham?

Lambeth’s noise guidance sets the window: weekdays 8am to 6pm, Saturdays 8am to 1pm, and no building work on Sundays or bank holidays. Keep drilling and breaking-out inside those hours, warn neighbours before the loudest days, and in a block or on an estate agree deliveries and access with the managing agent.

What should sit in every Streatham quotation?

Send every builder the same written scope and ask for itemised prices that treat VAT and professional fees alike. Make sure each one includes the skip licence, which Lambeth grants only to skip companies; the highways licence for scaffolding or hoarding, granted only once the fee and any deposit are paid; parking suspensions booked at least 10 working days ahead; provisional sums for hidden work; and any repairs to sashes, porches or front walls. Ask who will deal with building control and with Party Wall notices.

From which office do you serve Streatham, and what happens first?

Our studio is at Unit 3, Palace Court, 250 Finchley Road, London NW3 6DN, and we serve Streatham from this office. A short message with the full address, the rooms in question and some photographs is the place to start, and a free feasibility visit can follow; the lease, old plans and other papers can come after that visit.
