Flat refurbishment in Queen’s Park

Post-war estates, homes over shops and mansion blocks

Flats in Queen’s Park include those in the Mozart Estate’s post-war blocks on Westminster’s side and in buildings on Salusbury Road that Brent’s appraisal says were designed as mansion blocks, and the same road’s parades have homes above the shops. Who owns the building, and which council decides, shapes a flat refurbishment more than its size. This page covers those buildings, the landlord consents, the rules on splitting and joining homes, and the work beyond your front door.

Flat refurbishment in Queen’s Park at a glance

Before any layout is drawn, find out who owns the building. Westminster’s Queen’s Park Neighbourhood Plan says that more than half the homes in its area are rented from a registered social provider, and refers to the various housing associations working there, though it gives no date or source for those figures. Your lease or title shows whether the landlord is a housing association, a private freeholder or a council, and so whose written consent the work needs. On the Brent side, ask the same question about the homes above the Salusbury Road shops.

The buildings

Queen’s Park flats: estates, shop parades and mansion blocks

Both councils’ documents describe buildings here that may hold flats, but none says how each is owned or divided today, so read them as a guide to the type of building rather than to your lease.

Westminster’s May 2004 mini guide dates the first stage of the estate’s post-war redevelopment to Queen’s Park Court, built in 1951 on the Peach Street bomb site, followed in the 1970s by the Avenue Gardens and Mozart Estates, which replaced terraces on Droop Street and Third Avenue. The evidence annex to the Neighbourhood Plan records that the 1970 redevelopment of Mozart and Herries Streets built 870 dwellings in 31 red-brick residential blocks, and that the Mozart Estate suffered rising damp and poor insulation, with flats that were very expensive to heat. It does not describe their condition today.

The Neighbourhood Plan’s own area, enclosed by Kilburn Lane, the Harrow Road and the canal, and Fernhead and Portnall Roads, takes in the Victorian estate known locally as the Avenues, the 1970s Mozart and Harrow Road Estates, and shops and local amenities, mostly along Harrow Road and Kilburn Lane. Westminster’s 2005 audit describes the mixed retail and residential blocks on the estate’s Harrow Road edge as three storeys, higher than the estate’s usual type, reflecting their place on a busy road at its boundary. Neither document says how those upper floors are divided.

On Brent’s side, the 2024 appraisal for the conservation area’s extension describes a pair of buildings on Salusbury Road, by the same architect as the neighbouring terraces and with the same stone dressings, that were designed as mansion blocks and built by Solomon Barnett, or possibly Barnett and Brotchie; check Brent’s map to see whether they fall inside the final boundary. Brent’s Shopfronts SPD3 of June 2018, which Brent lists as adopted, names Queen’s Park among the borough’s Victorian shopping districts, which follow one format with classical details.

Permissions and local rules

Consents for a Queen’s Park flat

If a council is your landlord

What does each council ask of its own leaseholders?

Check your lease or title first. If Brent Council is the landlord, you must apply for its Landlord’s Consent before starting work such as new windows, a changed layout, removed walls or new openings, sending plans and any planning permission; a reply may take longer than 10 working days, and work done without consent needs a retrospective application at doubled fees. If Westminster City Council is the landlord, its formal permission is needed for work such as structural changes, layout changes, rewiring and internal or entrance doors, and works done without the right consent are flagged in conveyancing.

Splitting a house into flats in Brent

When will Brent allow a family house to be divided?

Brent’s Local Plan Policy BH11 lets a home of three or more bedrooms be split into two or more only where all three tests are met: 130 square metres or more, or acceptably extendable to it; at least one three-bedroom home, preferably with direct garden access; and a site rated PTAL 3 or above. Exceptions are allowed only where a home’s amenity is so deficient that family occupation is unlikely and cannot reasonably be remedied; the supporting text’s example is a home above a retail parade in a centre, which may suffer from opening hours, noise, smells and narrow access.

Protected homes on Westminster’s side

What applies on Westminster’s side?

Westminster’s City Plan 2019–2040, in the version adopted on 21 January 2026, protects all existing homes and residential floorspace, with exceptions that include reconfiguring smaller homes into family-sized ones. Within Westminster’s neighbourhood area, the Queen’s Park Neighbourhood Plan lists among its objectives protecting the existing social rented stock and resisting the subdivision of family units, while leaving the key housing policies to the City Plan. The neighbourhood plan applies to no Brent address, so check which side of the boundary your building is on.

Homes reached through a shopfront

What if your flat is above a Brent shop?

Brent’s Shopfronts SPD3 asks that a secondary door serving the upper floors be designed with the shopfront, and that services sit at the rear or be screened from the street. For a shop building converted into flats, it prefers access from the main street, with one external door opening to an internal door for each flat where the building is narrow, and asks that rear and side access be avoided, bins not dominate the frontage and satellite dishes be avoided on frontages where permission is required.

What the work covers

What a Queen’s Park flat refurbishment covers

Floors, ceilings and the home below

Flat work often starts with the floor, because new kitchens, bathrooms and hard finishes all sit on joists or slabs shared with the home below. The survey opens enough of the floor and ceiling to see how sound travels through it and where pipes and cables run, so that the new build-up meets Approved Document E where it applies and the lease’s flooring terms. The ceiling underneath belongs to a neighbour, so any access is agreed in advance.

GOV.UK: Approved Document E, resistance to sound · LEASE: alterations and home improvements

Pipes, risers and meters in a shared building

Water, heating, gas and the soil stack often pass through other homes on their way to yours, and in a building above shops some may serve the shop. Each service is traced to the point where your ownership ends before a new kitchen or bathroom position is fixed, and any work to a shared riser, meter cupboard or stack is agreed with the landlord before it is priced.

LEASE: alterations and home improvements

Your entrance door and the way out

A flat entrance door helps protect the stair in a fire, so its fire resistance and the closer that shuts it count for more than its appearance. In blocks Brent manages, the council’s fire safety advice to residents is not to damage, remove or wedge open internal doors, and to keep escape routes, including balcony walkways and shared landings and stairs, clear. Agree any change to the entrance door, and anything kept on a landing, with whoever manages the building.

How we work

How we run a Queen’s Park 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. Establish the landlord and the council

    Send the address, the floor the flat is on and the name of your freeholder or managing agent if you know it. In Queen’s Park that tells us whether Brent or Westminster deals with planning, and whether a council, a housing association or a private landlord must agree to the work.

  2. Collect the lease and past consents

    The alterations clause of your lease, any licence or letter of consent for earlier work and building control certificates show what has already been agreed. If walls were moved or a bathroom added before you bought the flat, those papers decide what can be built on and what may need putting right.

  3. Mark what affects other homes

    List the changes that touch someone else’s space or the outside of the building: a new floor finish, a moved kitchen or bathroom, a window, the entrance door or a pipe through an outside wall. Expect those to take longest to agree, so settle them before any finishes are chosen.

Questions before you begin

Flat refurbishment in Queen’s Park: questions

Do Westminster’s Article 4 rules for the estate apply to my flat?

Westminster’s Spring 1995 design guide records that flats and maisonettes were left out of the estate’s 1981 Article 4 direction because they had no permitted development rights, so alterations to them needed planning permission in any case. That direction was later cancelled, and Westminster’s Article 4 page now lists the Queen’s Park Estate for most properties. Treat any external change to a flat as likely to need permission, and note Westminster’s warning that its older guides may cite policies since replaced.

Which standards apply if a conversion creates new flats?

In Westminster, Part A of City Plan Policy 16 applies to new homes, residential extensions, merged flats and changes of use that create homes. The Nationally Described Space Standards apply to new-build dwellings, and Westminster, while accepting they are sometimes impracticable in heritage assets, expects them to be met when converting or extending homes where possible. In Brent, Local Plan Policy BH13 requires new homes to have private outdoor space, normally 50 square metres for a ground-floor family home and 20 square metres for all other homes.

Westminster City Plan 2019–2040, adopted version of January 2026 (PDF) · Brent Local Plan 2019–2041 (accessible version)

What if earlier work in the flat was never signed off?

For a Brent address, the council says it must be told when work is complete, or it cannot issue a completion certificate, which it warns will affect a later sale and may affect insurance. Where unauthorised work has been carried out, an owner may apply retrospectively for a regularisation certificate, and in some cases Brent could consider formal enforcement. For a Westminster address, ask its building control team. In either borough, check whether the lease also required a licence for that work.

Brent: the building control application process explained · LEASE: alterations and home improvements

Will Westminster agree to new windows if it is my landlord?

Possibly not. Westminster says that, as landlord, it is unlikely to approve replacement windows, rooflights in flat roofs or fire curtains in its leasehold flats. Its consent takes the form of a Letter of Consent on completion or a Licence for Alterations, and a Deed of Variation may also be needed, usually where the work is to something not demised to the flat, such as an extension. None of this applies unless Westminster is actually your landlord, so check the lease first.

Westminster: alterations by Westminster City Council leaseholders · LEASE: alterations and home improvements

Can two flats be turned back into one home?

Both councils allow it within limits. In Brent, Local Plan Policy BH10 supports a net loss of homes only in exceptional circumstances, one being the de-conversion of flats into a family home of three or more bedrooms with a net loss of no more than one home of two bedrooms or less. Westminster’s City Plan allows the loss of one non-family-sized home where it is reconfigured or merged with another to provide larger units, provided options to extend the building have first been explored. Expect the freeholder’s consent under the lease as well.

Brent Local Plan 2019–2041 (accessible version) · Westminster City Plan 2019–2040, adopted version of January 2026 (PDF) · LEASE: alterations and home improvements

Where should the family flat go if a Brent house is converted?

Brent’s Local Plan says that, where a larger house is suitable for conversion, the family-sized flat should ideally be on the ground floor if there is no lift, with direct access to its outdoor space, and that effort should be made to give every additional flat some amenity space. That guidance sits alongside Policy BH11’s three tests, so check the house against those before any layout is drawn, and ask Brent’s planning service early.

Brent Local Plan 2019–2041 (accessible version)

How much does a flat refurbishment cost in Queen’s Park?

Guide rates in Queen’s Park are £900–£1,700/sqm excluding VAT, with a full two-bedroom refurbishment typically between £60,000 and £110,000, over a 16–32 weeks programme. A written scope and site assessment come before any fixed price.
