Stanmore HA7 · Houses, flats & bathrooms

Renovations in Stanmore

Green Lane cottages, Tudorbethan houses and Modernist homes

Harrow’s December 2013 appraisals of Stanmore’s four conservation areas describe eighteenth- to early twentieth-century houses and terraced cottages on Stanmore Hill and Green Lane, 1930s Old World buildings around Old Church Lane and an unusual group of Modernist houses on Kerry Avenue. Plan your house, flat or bathroom around the building you actually have: how it was built, what has changed since and which controls apply at its exact HA7 address.

01 Cottages, period and Modernist houses

House refurbishment in Stanmore

Harrow’s Local Plan says almost two thirds of the borough’s housing stock dates from the inter-war period, and the 2013 guidance for Stanmore’s conservation areas, with homes from Green Lane’s terraced cottages to Kerry Avenue’s Modernist houses, values their predominantly single-family use. A measured survey should record surviving windows, roof coverings, chimneys and boundary walls before heating, wiring, insulation, bathrooms and finishes are drawn together as one scheme; price window, roof and boundary work once any Article 4 direction or listing is known.

  • Surviving windows, roofs and walls surveyed
  • Conservation map and Article 4 schedule read
  • Listing and local listing checked first

02 Flats and subdivided houses

Flat renovation in Stanmore

Harrow’s Local Plan records purpose-built flats increasing across the borough between 2011 and 2021 while the number of houses fell, and the Little Common appraisal notes that large houses such as Stanmore Hall and Springbok House remain, albeit subdivided or with their use changed. A flat has no Part 1 householder permitted development rights, and depending on the lease, the landlord’s permission may be needed for alterations even after planning or Building Regulations approval, so read it before a layout is drawn.

  • Alterations clauses in the lease checked
  • Freeholder’s consent sought first
  • Shared stacks and supplies located

03 Cottage, house and flat bathrooms

Bathroom renovation in Stanmore

Standalone bathroom renovations are welcome, whether a family bathroom in a Green Lane cottage, an en-suite in a larger house or the only bathroom in a flat. Before choosing fittings, establish how the floor is built, whether waste can fall to the soil stack, which in a flat may serve other homes too, and where extract air can leave. On some houses named in Harrow’s June 2023 Article 4 directions, installing or replacing a soil and vent pipe can need planning permission.

  • Waste fall to the soil stack confirmed
  • Extract route to the outside agreed
  • Article 4 or listing limits on pipes checked

Local knowledge with a purpose

Understand the building before changing it

Harrow’s December 2013 appraisals describe four Stanmore conservation areas: hillside houses and cottages on Stanmore Hill and Green Lane, large historic houses behind estate walls around Little Common, Old World buildings by Old Church Lane and Modernist houses on Kerry Avenue. What your home is made of and how it has been altered shape the survey; its exact address and the work you propose decide which approvals apply.

The Stanmore Hill appraisal describes houses and some commercial units from the eighteenth to the early twentieth century on sloping land, among greenery and historic walls. Linear development reflects properties built mainly to serve travellers heading to London along Stanmore Hill, many of whom would have stopped at the Abercorn Arms, an eighteenth-century hotel. Stanmore Hill and upper Green Lane are relatively dense, with small terraced cottages on Green Lane, many fronting the pavement; further down Green Lane, medium-sized detached houses in spacious grounds dominate. Buildings usually do not exceed two storeys, and most are listed or locally listed.

Harrow: Stanmore Hill Conservation Area Appraisal and Management Strategy, December 2013 (PDF)

Little Common, at 38 hectares the largest of the four in the 2013 SPD, gained cottages around the Common in the seventeenth century, then eighteenth- and nineteenth-century houses in large grounds, such as Stanmore Hall and Springbok House, which remain, subdivided or with their use changed. Tall walls mark historic estate boundaries, red and yellow brick and clay tiles are typical, and many original timber sashes and casements survive. Around Old Church Lane, the landowner Samuel Wallrock created an Old World, Tudor feel in the 1930s, using much older materials, and dark red handmade brick and clay tile predominate.

Kerry Avenue is different again. Its appraisal records an unusual concentration of inter-war and post-war houses in the Modern or International Style, laid out symmetrically on the axis of Stanmore Station, which opened on 10 December 1932 and became the terminus of the Metropolitan Line, and the 2013 SPD describes its well-preserved Modernist buildings as forming the earliest domestic group in west London. The houses are two or three storeys, with flat roofs often carrying sundecks and curved bays often holding the stair; all are brick, some designed with render to look like concrete against large Crittall windows.

The first local check

An HA7 postcode is not a planning answer

The name Stanmore and an HA7 postcode do not settle the council, a conservation area boundary, a listing, Article 4 coverage or the consent route. ONS lists Stanmore as an electoral ward in Harrow, while the 2013 SPD notes that the Brockley Hill scheduled monument extends partly into the London Borough of Barnet. Confirm the council for the address first. For a Harrow address, check Harrow’s current conservation area map and Article 4 schedule; for any address, check the listing records, the title or lease 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, flats and Article 4

Does the work need planning permission?

Work affecting only the interior of a Stanmore house or flat is generally not development, although that rule does not cover works that create new space underground. Outside, a flat has no Part 1 householder permitted development rights, and Harrow says conservation areas carry extra requirements for planning permission. For a house, check the permitted development limits, any conditions on earlier permissions and Harrow’s Article 4 schedules, which name individual properties in all four Stanmore conservation areas.

Listed buildings and the conservation areas

Does listing reach inside the building?

Yes. Harrow explains that consent is needed for any internal or external change that affects a listed building’s special interest, that the council decides whether consent is needed, and that failing to obtain it in advance is a criminal offence. Old Stanmore Church, the Church of St John, Stanmore Hall and 73 Stanmore Hill are listed at grade II*, and Hill House at grade II. A grade II list entry is named Green Lane Cottages, yet Harrow’s schedule marks Nos 1–4 Green Lane Cottages as locally listed, so check the entry for the exact cottage. A conservation area is a separate control, with its own rules on demolition and trees.

Building Regulations and Harrow Building Control

Who approves the building work itself?

Building Regulations approval is a separate regime from planning permission, listed building consent and a landlord’s consent, and a project can need more than one of them. Typical items to check include a bathroom with new plumbing, replacement windows and doors, and heating systems. Harrow runs its own Building Control service and takes applications online; decide for each item how it will be approved and who keeps the completion records at handover.

When Building Regulations approval is needed · Harrow: apply for Building Control · LEASE: alterations and home improvements

Freeholders, leases and shared walls

Who else may need to agree or be notified?

Depending on the terms of a Stanmore flat’s lease, the landlord’s permission may be needed before any alteration, even once planning permission or Building Regulations approval is in hand, so read the alterations clauses and contact the freeholder or managing agent before design starts. Party Wall notices apply only to work the Act covers, such as building at the boundary, working on a party wall or digging below and near to a neighbour’s foundation level.

Appraisals December 2013

Four Stanmore conservation areas

Harrow’s Stanmore and Edgware page lists Little Common, Stanmore Hill, Old Church Lane and Kerry Avenue, each with an appraisal, a map and an Article 4 entry. Each appraisal and management strategy is dated December 2013 and forms an appendix to the Stanmore and Edgware Conservation Areas SPD. Harrow’s map documents record the first three as adopted at Cabinet on 12 December 2013, and Kerry Avenue’s as adopted that December.

Harrow: Stanmore and Edgware conservation areas, with appraisals, maps and Article 4 entries · Harrow: Stanmore and Edgware Conservation Areas Supplementary Planning Document, December 2013 (PDF) · Harrow: Little Common Conservation Area map, schedule and Article 4 directions (PDF) · Harrow: Stanmore Hill Conservation Area map, schedule and Article 4 directions (PDF) · Harrow: Old Church Lane Conservation Area map, schedule and Article 4 directions (PDF) · Harrow: Kerry Avenue Conservation Area map, schedule and Article 4 directions (PDF)

The map documents give the designation history: Little Common designated in 1970, extended in 1987 and 2002 and amended in 2013; Stanmore Hill designated in 1975 and extended in 1980, 1991 and 2002; Old Church Lane designated in 1975 and extended five times, most recently in December 2013; and Kerry Avenue designated in 1980 and extended in 1986, 1991 and 1998. Some appraisal dates differ, such as 1969 for Little Common, so rely on the current map for the boundary.

Directions 1987 to June 2023

Article 4 directions on named properties

Harrow explains that an Article 4 direction removes permitted development rights, and its table marks directions as applying in all four Stanmore conservation areas. Each direction applies to the properties or land its schedule names, and most, including all those of June 2023, apply only where the works would front a highway, a waterway or open space. In the Stanmore Hill conservation area, the first schedule of the January 2003 direction, which carries that limit, names properties on Green Lane and on Stanmore Hill, including Nos 75–81 (odd), and controls extensions and alterations, roof changes, porches, hard surfaces, satellite antennas, gates, fences and walls, and exterior painting.

Directions confirmed on 9 June 2023 and in force from 20 June 2023 added controls on chimneys, flues and soil and vent pipes on houses named on Green Lane, Stanmore Hill, Wood Lane, Aylmer Close and Little Common; on works including replacement windows and doors, roofs, porches and painting at Applegarth, The Glade and The Orchard on Green Lane and at 147 Stanmore Hill; on boundaries at named properties on Green Lane, among them Greystones and Willow Lodge, and at 1–4 Rectory Close; on hard surfacing at 1 and 2 Gate House; and on new accesses to a highway at named buildings in the Kerry Avenue conservation area, including Stanmore Station.

Older directions remain on the schedules. Stanmore Hill’s of 12 December 2002 covers boundaries and hard surfacing at named properties, among them Park House and 1–4 Pinnacle Place. Old Church Lane’s of 12 July 2006 covers alterations, roofs, porches, satellite antennas and the painting of unpainted brickwork at 1 Uxbridge Road, The Manor House, 12 Manor House Estate and 1 and 2 The Gate House, and hard surfacing at Cherry Tree Cottage and the front gardens of 1–4 Rectory Close. Little Common has Cabinet directions of 14 January 2003 and a 1987 direction for Wood Farm.

On Kerry Avenue, an Article 4(2) direction in force since 1 February 1999 covers 1 Glanleam Road, 1–6 and 14–16 Kerry Avenue and 2–10 (even) Valencia Road, controlling alterations, porches, hard surfaces, boundaries and exterior painting, and a further Article 4(2) direction, confirmed on 20 May 2021, covers the demolition of gates, fences, walls and other means of enclosure.

Local Plan adopted 24 March 2026

The Harrow Local Plan and the 2013 guidance

Harrow’s Full Council adopted the Harrow Local Plan 2021–2041 on 24 March 2026. It is part of Harrow’s statutory development plan, alongside the London Plan and the West London Waste Plan 2015, and replaces the Local Plan adopted in 2012 and 2013. Policy HE1 supports proposals that preserve or enhance a heritage asset’s significance and assesses their impact through a Heritage Impact Assessment, which must accompany proposals to remove a feature or for new development in a conservation area.

Harrow: Harrow Local Plan 2021–2041, adopted 24 March 2026 · Harrow Local Plan 2021–2041, the adopted plan (PDF)

The December 2013 SPD was written to supplement a policy of the replaced 2013 plan; the new plan says conservation area SPDs, appraisals and management plans can provide further material considerations, so ask Harrow how it weighs them for a proposal. The SPD sets a presumption in favour of keeping single-family houses in these conservation areas, and the Stanmore Hill appraisal encourages any extension to sit at the rear, subservient to the house and matching its design and materials.

2013 SPD; 2026 Local Plan

Green Belt, listed buildings and the local list

Green Belt is a separate designation. The 2013 SPD places Stanmore Common, Grove Fields, Cloisters Wood, Stanmore Country Park and Pear Wood in the Green Belt and says most of Little Common lies within it, so extensions there face stricter control; Stanmore Hill is partly within it and Kerry Avenue bounds it. Local Plan policy GI1 considers Green Belt proposals under the NPPF, and the plan says inappropriate development will not be approved except in very special circumstances, so ask Harrow whether the address lies in it.

Harrow: Stanmore and Edgware Conservation Areas Supplementary Planning Document, December 2013 (PDF) · Harrow Local Plan 2021–2041, the adopted plan (PDF) · Planning Data: Harrow Green Belt record

Harrow counts over 300 listed building entries in the borough and 909 locally listed buildings, which are protected locally by planning policy rather than to the statutory standard. Stanmore Station is locally listed and part of the Kerry Avenue conservation area, and Harrow’s local list of parks and gardens includes Bernays Gardens, Stanmore Recreation Ground and Little Common, Stanmore. Ask Harrow whether a building or garden near the work is on the current lists.

Harrow: listed buildings · Harrow: locally listed buildings · Harrow: Stanmore and Edgware Conservation Areas Supplementary Planning Document, December 2013 (PDF) · Harrow: historic parks and gardens

Before ordering windows, re-covering a roof or digging, confirm the consent route for the exact Stanmore address and proposal. Planning permission, listed building consent, Building Regulations approval, lease consent and any Party Wall procedure are separate, and one never stands in for another. Whether planning permission is needed turns on the proposal, on whether the home is a house or a flat, and on conservation-area status and any Article 4 direction at that address; in the Green Belt, a proposal is also judged against Green Belt policy.

From retained details to shared services

Timber and Crittall windows, lime stucco, soil pipes and tree roots

Timber sashes, iron casements and Crittall windows

Start with the condition of each frame: an old sash or casement may be overhauled and draught-proofed rather than replaced. The Stanmore Hill appraisal calls original timber and iron windows important and says uPVC and aluminium detract from local character; on Kerry Avenue, large expanses of Crittall windows are part of the Modernist design. At named houses, June 2023 directions expressly cover replacing windows and doors that front a highway, waterway or open space; Harrow expects timber in window repairs to listed buildings, and replacement windows can need Building Regulations approval.

Soil pipes, extract vents and lime stucco

In a flat, the bathroom often drains to a soil stack shared with other homes, so plan the layout from that stack and read the lease before moving it. On houses named in Harrow’s June 2023 Article 4 directions for Stanmore Hill and Little Common, installing or replacing a soil and vent pipe, chimney or flue can need planning permission, so read the direction before routing a pipe outside. Where a vent passes through stucco, keep cement out of the repair: the Stanmore Hill appraisal says adding cement to lime render detracts from breathability.

Floors, partitions and structural changes

Open up small areas first to see how each floor is framed and which partitions carry load, before removing a wall or choosing stone or tiled flooring. Between flats, agree the floor build-up with the landlord before choosing hard finishes. Internal alterations to a listed building can need consent where they affect its special interest. In Little Common, the SPD links the Green Belt limits on extending to pressure for part demolition and rebuild, and in a conservation area, demolishing an unlisted building, sometimes even in part, needs planning permission.

When Building Regulations approval is needed · LEASE: alterations and home improvements · Harrow: listed buildings · Harrow: Stanmore and Edgware Conservation Areas Supplementary Planning Document, December 2013 (PDF) · Harrow: conservation areas and Article 4

Estate walls, hedges and front gardens

The Stanmore Hill appraisal describes dense planting, timber fences no higher than 1.5m, hedges and low brick walls, with some tall historic walls marking the bounds of large houses, and the Little Common appraisal counts tall estate walls among its defining features. The 2013 SPD seeks porous surfaces and at least two thirds soft landscaping in front gardens, and several Stanmore Article 4 directions bring boundary changes, their demolition or hard surfacing under planning control.

Basements, tree roots and archaeology

Refitting an existing lower-ground room differs from digging new space. Harrow’s policy GR4A supports basements for ancillary accommodation where, among other tests, they take no more than half a site’s amenity space, extend into the rear garden no more than half the house’s depth and do not worsen flood risk, groundwater or ground stability or harm tree roots; self-contained basement homes are not supported, and every proposal needs a Construction Method Statement. The 2013 SPD says all conservation-area trees are protected and names the former medieval village of Great Stanmore as an Archaeological Priority Area.

Insulation first, then equipment

The 2013 SPD encourages basic energy efficiency work, such as loft and wall insulation and draught-proofing, before any microgeneration equipment, and says the sloping ground of the Stanmore Hill and Kerry Avenue conservation areas makes them most sensitive to such equipment. On traditionally built walls, the Stanmore Hill appraisal warns that adding cement to lime render detracts from their breathability, so choose renders and finishes with that in mind. Check any listing and Article 4 direction before adding external insulation, panels or flues.

A practical plan for the street and building

Working hours, deliveries and shared access

Skips, scaffolding and parking on Harrow roads

Plan deliveries, waste and protection for any shared hall or drive before work starts. In Harrow, a skip on the public highway needs a skip licence, which the skip company obtains; scaffolding on the highway needs a licence, issued only to the scaffolding company; and building materials on the highway need a licence even briefly, placed on the carriageway rather than the footway. Allow up to 10 working days for a skip licence or a parking-bay suspension, and never reserve a space with cones or bins. TfL licenses these only on its red routes.

Harrow’s noisy-work hours and living at home

Under powers in the Control of Pollution Act 1974, Harrow permits noisy construction work from 8am to 6pm, Monday to Friday, and 8am to 1pm on Saturday, with none on Sundays or bank holidays, and suggests warning neighbours in advance about the work and how long it will last. In a flat, ask the managing agent about any building rules on working hours, deliveries and common parts, and if you stay at home, agree which rooms remain in use and when water or power will be off.

A clear scope before a price

Plan your renovation budget and quotation

Comparable quotations start from one written scope that every contractor prices. Group the rooms together, list window, roof, render and boundary repairs separately, then any structural work, and hold apart each item that depends on a landlord, a neighbour or listed building consent.

The home as it stands

Separate the repairs you can see today from those that opening up may reveal.

  • Measured drawings and photographs of each room
  • Original windows, doors, stucco and walls to keep
  • Timber, damp or drainage to open up and inspect

Rooms, finishes and services

Specify each room closely enough that every contractor prices the same thing.

  • Fittings and finishes listed with quantities
  • Heating, wiring, plumbing and extract set out
  • Items you supply, with delivery dates

Approvals and site arrangements

List the consents, notices and street licences the work needs, with a name against each.

  • Listing, Article 4 and Green Belt answers
  • Party Wall notices where the Act applies
  • Skip, scaffold and bay suspension licences

Written allowances and sequence

Record the allowance for each unknown and the date each open decision is needed.

  • Provisional sums and VAT shown separately
  • Order dates for windows and fittings
  • Building Control inspections and certificates

Being in Stanmore does not add a fixed surcharge to a quotation or decide how long the work will take. Ask each contractor to state how VAT and any professional fees are handled, and how anything found on opening up will be priced. A standalone bathroom receives its own quotation, written for that room alone.

From an idea to a workable scope

Prepare your brief and renovation budget

  1. Describe the house or flat

    Send the full address and tell us what kind of home it is: a cottage, a larger period house, a Modernist house or a flat, giving the floor and type of building for a flat. Add photographs of every room involved, the front elevation and boundary, and any damp, cracking or leaks you have seen.

  2. Gather what you already have

    Collect the papers that answer questions early: drawings, the title or lease, any rules for the building, Building Control completion certificates and decisions on past planning or listed building applications. Note what you know about listing, local listing, the conservation area, Article 4 directions and any protected tree close to the work.

  3. Name the open questions

    Separate what is decided from what is not. A structural engineer’s findings, a drainage survey, the landlord’s answer or the council’s view on consent may still be outstanding; list each one, so that every quotation includes the same written allowance for it.

  4. Put names and dates to each task

    Decide who applies for each consent, serves each notice, obtains each licence and books each inspection. Plan deliveries around the road outside and the council’s hours for noisy work, say whether you will stay at home during the works, and agree in writing how changes and the handover file will be handled.

Questions before you begin

Renovating in Stanmore: practical answers

Can a single bathroom in a Stanmore house or flat be a standalone project?

Yes. A single bathroom, en-suite or shower room in a Stanmore house or flat can be renovated as a standalone project, without any wider refurbishment. Send the room’s measurements, photographs and current layout, the route of the soil stack if you know it, and whether another bathroom can be used while the work is under way.

Is my Stanmore home inside a conservation area?

That depends on the boundary, not the name. Harrow lists four Stanmore conservation areas, Little Common, Stanmore Hill, Old Church Lane and Kerry Avenue, each with an appraisal dated December 2013 and a current map. Several roads lie only partly inside, among them Stanmore Hill, Aylmer Drive, Old Church Lane and Valencia Road, so look the full address up on Harrow’s current map; an HA7 postcode cannot tell you.

Harrow’s Stanmore Article 4 directions apply to the properties named in each schedule, mostly only where the work would front a highway, waterway or open space, and cover items such as extensions, roofs, porches, hard surfaces, boundaries and painting, adding chimneys, flues, soil pipes and replacement windows on some houses from June 2023. Listings are individual entries: Stanmore Hall, Old Stanmore Church and 73 Stanmore Hill are grade II*, Springbok House and the Abercorn Arms grade II.

Can I replace windows or add double glazing in Stanmore?

Start from the frames you have: overhauling and draught-proofing a timber or iron window may give the comfort you want. The Stanmore Hill appraisal says uPVC and aluminium detract from local character, Kerry Avenue’s Modernist houses were designed with large expanses of Crittall windows, and June 2023 Article 4 directions expressly cover replacement windows and doors at named houses where they front a highway, waterway or open space. A listing, the lack of householder permitted development rights for flats, a lease’s window clauses and the Building Regulations for replacement windows each need a separate check.

Whose agreement do I need for internal changes to a Stanmore flat?

Internal changes do not usually need planning permission, because work affecting only the interior is generally not development, although outside changes differ, as flats have no Part 1 householder permitted development rights. Start with the lease: depending on its terms, the landlord’s permission may be needed for any alteration, even with planning permission or Building Regulations approval. New bathroom plumbing can need Building Regulations approval, and in a listed building, internal changes affecting its special interest need listed building consent.

Can I remove a wall or move the bathroom?

That depends on the structure and the drainage. A structural engineer should confirm which walls carry loads and how the floors are framed, in a Green Lane cottage as much as a flat-roofed Kerry Avenue house. Whether a bathroom can move depends on the drainage fall to the stack and a route for extract air to the outside. Building Regulations, the lease, any listing and the Party Wall Act also need checking before the layout is fixed.

Can I add a basement or lower-ground room in Stanmore?

Refitting an existing lower-ground room stays within the house, but the interior exemption in the planning statute does not cover new underground space. Harrow’s policy GR4A supports basements for ancillary accommodation within set limits, but not as self-contained homes, and every proposal needs a Construction Method Statement. Harrow’s Local Plan refers soil stability to Building Control rather than planning, and new basements in an Archaeological Priority Area should be informed by consultation with the Greater London Archaeological Advisory Service. Digging below and near to a neighbour’s foundation level can also need a Party Wall notice.

What hours apply to noisy building work in Stanmore?

For an address in Harrow, the council permits noisy construction work from 8am to 6pm, Monday to Friday, and 8am to 1pm on Saturday, with none on Sundays or bank holidays, and suggests warning neighbours in advance about the work and how long it will last. In a flat, check the lease and any building rules on noise and deliveries before the programme is agreed.

How do I compare quotations fairly?

Send every contractor the same written scope, listing the rooms, quantities, services, finishes, features to keep and repairs already known. Then set the quotations side by side and compare how each treats VAT, professional fees, consents, licences, protection and provisional sums; the totals mean little until the main unknowns are investigated. A Stanmore postcode alone is no reason for a higher price or a particular finishing date.

Where is your studio, and what should I send first?

Our studio is in Hampstead, at Unit 3, Palace Court, 250 Finchley Road, London NW3 6DN, and we serve Stanmore from this office. To begin, send the address, the rooms you want to change and a few photographs; drawings, the lease and any consent papers can follow, along with what matters most to you in the budget.
