Flat refurbishment in Stanmore

Mansion apartments, flats over parades and post-war blocks

Harrow’s records describe Stanmore flats of several kinds: apartments inside listed former mansions, small conversions of a cottage and outbuildings, homes above the 1960s shopping parades and post-war blocks along the main roads. This page helps you place your flat among them, shows who must agree to the work in each case, and sets out what Harrow’s policies say about noise, layout and dividing a home further.

Flat refurbishment in Stanmore at a glance

In Stanmore, the kind of building your flat is in decides who has a say, before the lease is even opened. In Stanmore Hall, listed grade II*, and Hill House, grade II, the flats are inside listed buildings, so listing adds its own consent question to the freeholder’s. In 2011 the upper floors of the district centre’s 1960s parades held a mix of homes and businesses. Where Harrow Council is the freeholder, because the flat or maisonette was bought from the council, its Housing department’s written permission comes before any change. In other blocks, the lease says whether, and whose, consent you need.

The buildings

Where Stanmore’s flats are, as Harrow describes them

Harrow’s appraisals and its 2011 assessment of residential areas describe flats of very different kinds: converted mansions, a cottage and outbuildings in Little Common, a single block on Kerry Avenue, homes above parades and post-war blocks by the main roads.

The December 2013 Little Common appraisal records that two of the area’s three former mansions, Stanmore Hall and Hill House, have been converted into apartment blocks, while the third, Springbok House, is a religious centre. Stanmore Hall, built about 1843, was restored and extended as offices before it was converted into apartments. Smaller conversions sit nearby: a mid-Victorian cottage in Little Common, with octagonal chimney stacks and blue diaper brickwork, is now subdivided into flats, and the outbuildings of the Old Brewery House on Stanmore Hill have been converted to flats.

The same appraisal notes newer flats: a modern block beside the small green by The Vine, taller than its neighbours, which it finds quite successful in fitting in, and new flats and houses just west of the Old Brewery House in Park Lane. Two other conservation areas had few flats in 2013: the Stanmore Hill appraisal found only one house subdivided into flats in the conservation area and its surroundings on Green Lane, and the Kerry Avenue appraisal said the only flats there were the seven in Kerry House, a two- and three-storey block that replaced the 1937 Kerry House.

Harrow’s 2011 Character Assessment describes 1960s three-storey, flat-roofed parades in light brown brick at Stanmore Hill and The Broadway and on the south side of Church Road, with a mix of residential and commercial uses on their upper floors at that time. It gives Uxbridge Road, London Road and Marsh Lane as examples of ribbons of post-war infill flats, and Marsh Lane for larger areas of maisonettes. Harrow Council’s list of the estates it inspects includes a Glebe Estate on roads including Little Common and Rainsford Close; the list does not say which of its homes are flats.

Permissions and local rules

Who must agree to work on a Stanmore flat

A flat inside a listed former mansion

What changes when the flat is in a listed building?

Stanmore Hall (grade II*) and Hill House (grade II) are both statutory list entries, and the Little Common appraisal says both are now flats or apartments. An owner there may need two separate permissions: the freeholder’s, where the lease requires it, and Harrow’s, where listed building consent is needed. Neither stands in for the other. Neither the appraisal nor the Planning Data list record says whether the converted outbuildings of the Old Brewery House, itself listed grade II, fall within that listing, so ask Harrow before planning work there.

If Harrow Council is your freeholder

What do Harrow’s rules for its own leaseholders require?

These rules apply only to a flat or maisonette bought from Harrow Council, through Right to Buy or from a previous owner. Written permission from the council’s Housing department is needed before making any change to the property. The council will not grant permission to buy and extend into the loft space, or for ground-floor extensions on its estates. Its permission is separate from planning and building control: some alterations also need planning permission, and building control may be needed, which the leaseholder applies and pays for.

Homes above Stanmore’s parades

What do Harrow’s centre policies say about a flat over a shop?

Harrow’s adopted Local Plan treats Stanmore as a District Centre and lists Stanmore Hill, south of the Green Lane junction, as a Neighbourhood Parade. Policy LE1 supports homes in town centres, but providing access to them is appropriate only where any resulting loss of active frontage or floorspace is carefully managed, and mixed-use schemes need clearly separated access and servicing, such as bin and cycle stores. The supporting text to policy HO2 names maisonettes above shops among the homes where over-intensive conversion leads to poor living conditions and excessive internal noise transfer.

Sound and fire between homes

What do the noise and fire rules ask of a flat?

Harrow’s plan says noise transfer between homes can be as critical to privacy as overlooking; sound insulation is a matter for the Building Regulations, but the internal layout of rooms can help to reduce it. Since 23 January 2023, in a multi-occupied residential building with storeys over 11 metres, the responsible person must, as far as they can, check all flat entrance doors onto the common parts, with their self-closers, once a year.

What the work covers

What a Stanmore flat refurbishment covers

Floors, ceilings and the homes around you

Where hard floors replace carpet, or a room changes use, the scope sets out the floor and ceiling build-up and the sound insulation it needs, and arranges rooms with the neighbouring flats in mind. In a converted mansion or cottage the floors may be old timber; small areas are opened first, so that the build-up is designed around what is actually found rather than assumed.

GOV.UK: Approved Document E, resistance to sound

Services shared with the building

The scope traces which pipes, risers, flues and cables serve other flats, where the stopcock and consumer unit are, and what the freeholder must approve before anything shared is touched. For a flat bought from Harrow Council, the council recommends an annual Gas Safe inspection of gas appliances and an electrical safety inspection every five years, with the certificates sent to it, so the work is planned to leave those records up to date.

Harrow Council: home alterations permission for leaseholders

Entrance door, windows and common parts

The flat’s entrance door, where it opens onto a shared hall or stair, is specified with the freeholder or managing agent, together with any self-closer. Window changes are agreed with the freeholder and checked for planning permission before anything is ordered. Protection of the stairs and halls, the route for deliveries and waste, and the times the common parts can be used are written into the programme.

How we work

How we run a Stanmore flat refurbishment

  1. First visit

    We see the flat, then the entrance, stairs or lift that serve it.

  2. Lease and consents

    We go through the lease’s consent requirements with you and the managing agent at the start.

  3. Survey and design

    Drainage and services are traced on site. Our own architects and structural engineers design the layout and any structural change around those routes, and any new external vent or window is checked for planning.

  4. Price and contract

    A fixed written price and a JCT contract follow the survey, scope and specification. The price names its allowances and exclusions, with consent fees and any common-parts work shown separately.

  5. Working in the building

    Common parts are protected and their condition recorded; deliveries keep to the building’s rules, and noisy work to those rules and the council’s permitted hours; key decisions go to a director.

  6. Handover

    Commissioning, drawings, certificates and any managing-agent close-out. Completed work carries a 12-month defects-rectification period under the JCT contract terms.

Your brief

Before you ask for a quotation

  1. Say who owns the building

    Tell us who the freeholder or managing agent is, and whether the flat was bought from Harrow Council or from a previous owner of a council flat. Send the lease, or at least its alterations clauses, and any building rules, so that every consent can be listed before design starts.

  2. Describe the building

    Say whether the flat is in a converted house or mansion, above a shop or in a purpose-built block, which floor it is on, how many storeys the building has and roughly how tall it is, and whether it is listed or in a conservation area.

  3. Name the rooms that change

    List the rooms you want to change and whether any moves, for example a kitchen into a former bedroom. Note which walls and floors you share with neighbours and what lies above and below, so that sound, access and working times can be planned with them.

Questions before you begin

Flat refurbishment in Stanmore: questions

What does Harrow charge its leaseholders for permission to alter a flat?

Harrow’s leaseholder charges page lists a licence for alterations at separate rates for major, standard and minor improvements, each plus reasonable legal costs, a fixed charge for a surveyor’s visit covering the first two hours and an hourly rate after that, and an extra charge on top of the standard fee for retrospective consent. The page carries no date, so treat its figures as those published when checked on 16 October 2026, and confirm them when you apply. They apply only where Harrow Council is the freeholder.

Harrow Council: leaseholder administration charges (undated page, checked 16 October 2026)

Does Harrow insure a flat bought from the council?

In most cases Harrow arranges the building insurance for its leaseholders’ flats and recovers each share of the cost through the service charge, but contents cover is not included. Before work starts, ask the council how its policy treats alterations inside your flat, and make sure your own contents and belongings are insured while rooms are emptied and stored.

Harrow Council: home alterations permission for leaseholders

What does Harrow ask of a home being divided into flats?

Harrow’s Local Plan refuses proposals that would lead to an over-intensive conversion. For conversions of houses into flats, policy HO2 requires homes to be dual aspect, with a satisfactory environment for privacy, daylight, sunlight, outlook and external noise, and that the ground-floor flat suits a range of residents, particularly older people and those with physical disabilities. The 2010 Residential Design Guide adds that flats solely in the roofspace of most suburban houses are unlikely to be acceptable, though they may be in larger properties where headroom and circulation space allow.

Harrow Local Plan 2021–2041, the adopted plan (PDF) · Harrow: Residential Design Guide Supplementary Planning Document, adopted 15 December 2010 (PDF, file 23276)

Who looks after the shared parts of a Harrow council estate?

Harrow says a leaseholder who bought from the council does not own the land the property stands on, and that the council still maintains the structure and communal areas of the estate. It carries out formal inspections of each housing estate, covering communal repairs, internal block clearing, caretaking and grounds maintenance. If opening up your flat reveals a defect in the structure or a shared part, report it to the council rather than repairing it yourself.

Why does the Stanmore Hill appraisal resist flat conversions?

Its management strategy says to resist proposals for flat conversions, because conversion would increase pressure for alterations and detract from the area’s suburban character. The appraisal adds that converting the shops, café and pub at the upper end of Stanmore Hill to offices or homes would reduce the area’s vitality. This concerns dividing houses or changing the use of those buildings, not refurbishing a flat that already exists.
