Builders and plumbers in Stanmore, HA7

Harrow has 30 conservation areas, and it gathers the Stanmore and Edgware group on a single page. That page lists Little Common, Stanmore Hill, Old Church Lane, Kerry Avenue, Edgware High Street and Canons Park Estate. Each has its own appraisal and management strategy, with its own boundary and history of change.

For a Stanmore house, the first task is to establish which of these, if any, contains the plot. Boundaries have moved over the decades, so an old sale brochure or a neighbour’s memory is not a reliable guide. The current map and appraisal settle it for the exact address.

Inside a conservation area, the council expects external changes to respect the character its appraisal describes. Where an Article 4 direction applies, Harrow’s page explains, planning permission is needed for the work it covers. Outside a boundary, a house may still sit beside Green Belt or a listed building, and that setting is checked too.

Harrow designated the Stanmore Hill Conservation Area in 1975, around the meeting of Green Lane and Stanmore Hill. It was extended in 1980 and amended again in 2003. The current appraisal replaced a policy statement adopted in October 2003.

The appraisal describes houses and some commercial units from the eighteenth to the early twentieth century, set on sloping land. It finds a traditional village character in modest, small-scale terraces. Some combine brick with tile hanging or weatherboarding, while others use white render.

It also records that Article 4(2) directions add to the usual conservation area controls here. A further direction was proposed for named houses on Green Lane, covering rooflights, roof alterations such as chimney removal, and porch extensions. Whether that proposal was confirmed is not something the published appraisal settles, so it is checked for the house in question. On sloping land, roof and rear changes can be seen from further down the hill.

Little Common was first designated in 1969. It was extended in 1987 to take in more of Wood Lane, and again in 2003. Its appraisal explains that the Common was originally manorial waste, and that cottages grew up beside it piecemeal in the seventeenth century.

Old Church Lane was designated in 1975. Its first boundary enclosed the church and churchyard of St John the Evangelist and Bernays Gardens. The appraisal notes a number of timber-framed buildings, some of medieval origin. Historic England lists Old Stanmore Church at Grade II*. The entry dates it to 1632, attributes it to Nicholas Stone and records red brick with Portland stone dressings.

Older buildings like these are surveyed before any repair is priced. We record how the frame, roof and walls carry load, and which materials earlier repairs introduced. Repairs are then specified to match what is found, rather than a standard detail.

Kerry Avenue was first designated in 1980, with its boundary amended in 1986 and 1991. Its appraisal describes a mainly residential area of inter-war International or Modern Movement architecture, with some post-war homes of quality. It dates a local listing to 29 October 1973. In May of the following year, the Secretary of State was asked to approve an Article 4 direction. Whether any direction applies today is confirmed from Harrow’s current documents.

The conservation area lies north-east of Stanmore District Centre and immediately south of Stanmore Country Park. It includes Stanmore station, which is on the Jubilee line.

In a Modern Movement setting, the original windows, wall finishes and roof edges are recorded before any change is proposed. Where replacement is needed, profiles and finishes are drawn up and discussed with the council before an order is placed. Replacement windows and roof coverings also carry Building Regulations requirements, which are settled alongside the design.

Harrow’s Stanmore and Edgware conservation guidance says Green Belt stretches across the north of the borough, with numerous areas in Stanmore. It names Stanmore Common, Grove Fields and Cloisters Wood among them. The Kerry Avenue appraisal adds that the conservation area borders Stanmore Country Park, a designated Green Belt and an Area of Special Character.

Harrow’s adopted Local Plan also identifies the Royal National Orthopaedic Hospital site as a significant strategic site in an existing Green Belt use.

For a house on or near that open land, the Green Belt boundary is confirmed on the policies map before design starts. National planning policy restricts new building in the Green Belt, with limited exceptions that include extensions which are not disproportionate to the original building. Views from the open land towards houses also matter, so rear elevations, garden buildings, lighting and boundary treatments are designed with that edge in mind.

Historic England lists the central entrance block of Bentley Priory at Grade II*. The entry attributes it to Sir John Soane, 1789-90. It also notes the building’s interest as the headquarters of Fighter Command during the Battle of Britain and until 1968. Bentley Priory appears on the register of parks and gardens at Grade II as well.

A house need not be listed itself for a nearby listed building or registered landscape to matter. The setting of a heritage asset can be a material consideration in a planning decision. Height, bulk, materials and views are therefore tested against that setting at sketch stage.

Where a building is listed, listed building consent is needed for works that affect its character. Carrying out such works without consent is an offence, and internal alterations are included. The list entry helps identify the building, but it does not define everything that is protected. The building itself is examined before a scope is written.

A skip standing on the public highway needs a Harrow skip licence, and scaffolding on the highway needs a licence held by the scaffold provider. Harrow describes a controlled parking zone as a place where yellow lines apply or a permit is required to park.

In Stanmore, these arrangements belong in the design stage rather than at the end. Where a front garden or drive can take a skip, the highway may not be needed at all. Harrow’s trees page confirms that a tree may be protected by an order or by standing in a conservation area. Root areas near that position are checked first. Where the highway is needed, licence applications are made before a start date is fixed.

Stanmore and Canons Park stations are both on the Jubilee line. Work is carried out in-house by Hampstead Renovations or Hampstead Maintenance after a written scope. The same team keeps each licence condition in view on site.

By the end of a project, a Stanmore house may have gathered several separate permissions. Planning permission, or a lawful development certificate, answers the planning question. Listed building consent answers the heritage question where the building is listed. A tree notice or consent covers protected trees. Building Regulations approval is a separate process again, ending in a completion certificate.

Flats add another layer. The lease sets out what a leaseholder may alter, and the freeholder’s consent is obtained before structural or external work begins. Between neighbours, the Party Wall etc. Act requires notice before certain work to a shared wall or excavation near an adjoining building.

We assemble this file as the work proceeds, not at the end. It holds the decision notices, the appraisal extracts used in design, drawings as built, photographs of concealed structure and the completion certificate. Where designations overlap, that record lets a later owner or the council see that each step was authorised.
