Builders and plumbers in North Finchley, N12

Before layouts are discussed, a North Finchley property needs two questions answered: who owns which parts, and how the building is put together. A freehold house gives one owner control of the structure, subject to planning. In many leases, a flat owner holds the interior while the roof, main walls and shared drains stay with the freeholder. A flat above a shop adds a commercial occupier with its own lease, trading hours and services.

Those differences decide who must agree to the work, who pays for each element and who can authorise access. So we start with the title and, for a flat, the lease plan and repairing covenants. We note the managing agent, the freeholder’s consent process and any restriction on alterations. Only then is the physical survey planned, because the lease can define which walls, floors and ceilings belong to whom.

Where a flat sits over a shop, restaurant or office, the two uses share more than a floor. Water, gas and electricity supplies may pass through the commercial unit. Extract ducts or refrigeration plant may stand on a flat roof below the flat’s windows. The floor between them may carry fire separation and sound insulation fitted during a past conversion.

For repairs, a leak, smell or electrical fault is traced across both occupancies before anything is opened. For alterations, fire separation, escape routes and sound insulation are Building Regulations matters, handled apart from planning. Access may depend on the commercial tenant’s hours, or on a rear yard or service door the flat does not control. If different people own the flat and the unit beneath, the Party Wall etc. Act can treat the dividing floor as a party structure. Arrangements are agreed in writing with each occupier before work begins.

Barnet’s character appraisal for Moss Hall Crescent is dated 26 August 2015. It locates the conservation area south of Tally Ho Corner, on the western side of Ballards Lane. The council designated it in July 1974. The appraisal describes twelve Victorian villas set back from Ballards Lane by a strip of green open space. It credits a strong tree line with softening the impact of heavy traffic. It also refers to Moss Hall as a Georgian manor house, whose estate was laid out and subdivided into plots for development from 1867.

For anyone planning work on one of the villas, the appraisal is the first document to read. It records that some harmful alterations have taken place. Its examples are replaced windows, doors and roofing materials, and removed front boundary walls and fences. Repairs to them are specified with the appraisal in hand, so renewal does not become another loss.

Barnet’s 2015 appraisal says an Article 4(1) direction was implemented at Moss Hall Crescent in July 1987. It lists classes relating purely to the dwelling houses, among them the enlargement, improvement or other alteration of a dwelling house. Other classes in it apply to all properties, including gates, fences, walls and painting. An Article 4 direction withdraws specified permitted development rights, so work that would otherwise be allowed needs a planning application.

Form and tenure still matter. The appraisal notes that most of the former houses are now self-contained flats, which do not carry the full range of permitted development rights. It records two existing directions and recommends that the council update them to reflect current legislative wording. Whether that has happened is not assumed. For an address in the crescent, we read the current direction and boundary map before advising on any external change. A lessee also needs the freeholder’s consent, sought alongside any planning route.

A lease can permit, restrict or forbid alterations, and it may require the landlord’s written licence before work starts. Structural openings, a bathroom moved over another flat’s bedroom, hard floor finishes and new external flues can each trigger that requirement. Where a managing agent acts for the freeholder, the licence request passes through the agent, with drawings and a method statement attached.

We read the relevant clauses before drafting a scope, not after. If a licence is needed, the drawings are prepared to answer the freeholder’s likely questions on structure, sound and water. Repairs to the roof, main walls or shared drains may be the freeholder’s responsibility, funded through the service charge. In that case the lessee’s role is to report and record the defect, and our scope covers only the lessee’s own parts. The written scope names each consent obtained and who granted it.

Building Regulations approval is separate from planning permission, and a flat refit can engage several regulations at once. Moving a kitchen or bathroom affects drainage and ventilation. Opening a wall affects structure. Changes near an entrance door or a shared stair can alter the escape route that protects every flat in the building. New electrical work has its own standards and must be tested and recorded at the end.

The approval route suits the work: full plans where design questions need settling first, or a building notice where the rules allow one. The building control body inspects at key stages, and a completion certificate closes the file. For a leasehold flat, the freeholder or managing agent may ask to see that approval before granting a licence. Planning, building control, lease consent and party wall matters run as separate lines, because approval under one never implies approval under another.

For an upper-floor flat, materials go up a shared stair or through a rear yard, and waste comes down the same way. That route may cross common parts the lessee does not own, so the freeholder or agent agrees protection and timing. If the only rear access runs through a commercial unit’s yard, its tenant has to agree as well. Heavy items such as steel beams or baths are sized against the narrowest turn on the route before they are ordered.

At the front, kerb rules are confirmed for the exact address. The High Road through North Finchley is part of the A1000. A High Road or Ballards Lane frontage may be a TfL red route or a borough road. That is checked against TfL’s information and the kerbside signs, not assumed. Deliveries are then booked in small loads at times that suit the road and the building’s other occupiers.

Once the consents are in place and the scope is agreed in writing, the work is carried out in-house by Hampstead Renovations or Hampstead Maintenance. Renovation and alteration sit with Hampstead Renovations, and repair and upkeep with Hampstead Maintenance. Where a building has several owners, each is told in advance what will happen in their part of it and whom to contact.

The completion file is divided the way the building is. The lessee receives records for work inside the flat, including building control completion evidence and test results for new services. The freeholder or managing agent receives copies of anything touching the structure, common parts or shared services, with the licence to alter. For a house in Moss Hall Crescent, any planning decision is filed with photographs of windows, doors and boundaries before and after. Each record is labelled with the address and the part of the building it concerns.
