House refurbishment in Winchmore Hill

Old village houses, where repair often comes before renewal

Several groups of houses near The Green and on Vicars Moor Lane are listed, and others are named in the 2006 Article 4 schedule, so a whole-house refurbishment here often turns on small details. This page sets out what Enfield’s decisions on listed houses have required, the 2015 view that lost details can be reinstated, the tests for rear extensions, what one basement consent required, and the flood evidence worth reading before any digging.

House refurbishment in Winchmore Hill at a glance

The council’s management proposals of 2015 for both conservation areas treat uPVC windows, concrete roof tiles, false shutters and painted brick as evidence of a gradual erosion of character through cumulative change. Now that such changes are controlled through planning, they add, they more often offer a chance to reinstate original details than a threat. On Hoppers Road, the 2015 appraisal finds Compton Terrace, a mansard-roofed, two-storey Victorian terrace, marred by widespread and varied modern replacement that destroys its unity. A refurbishment here can therefore put lost details back as well as renew the rooms.

The buildings

Winchmore Hill houses: listed rows, old fronts and what survives

Three things shape a whole-house job on the older houses here: the listed terrace on Vicars Moor Lane, the oldest rendered walls near The Green and on Wades Hill, and how much original detail the rest still keep.

On the north side of Vicars Moor Lane, the appraisal picks out the listed group at 68 to 76, built in 1871 in an archaic Regency style. When Enfield granted listed building consent in November 2014 for basement, rear extension, layout, sash, loft and garage works at one of the listed houses in this terrace, its conditions reached inside: 1:20 drawings of how new staircases would meet the structural walls, protection of interior elements during the work, hand demolition of the old rear extension and side wall, and steps to keep retained parts stable before work began.

Some of the oldest walls are rendered. The listed Rowan Tree House and Woodside House, tucked into the south-western corner of The Green, is described by the appraisal as an early 18th-century house with a part-painted, part-rendered front and later architraves. At one of the listed early 19th-century cottages at 17–21 Wades Hill, Enfield granted listed building consent in September 2024 to strip part of the rear render and apply a new hydrated lime render, on conditions that the finishes match the approved lime products and that demolition be done by hand or with non-powered hand tools.

The 2015 documents found much of the rest in good condition. The appraisal’s summary says that most buildings in the two conservation areas keep their original outward appearance, windows and doors included, and the 2015 management proposals describe the buildings as generally in very good order, with no entries for either area on English Heritage’s 2012 Register of Heritage at Risk in London. On Wades Hill, though, the appraisal says the mid 19th-century cottages with distinctive hipped roofs at 50 to 56 have been particularly harmed by uPVC sashes and concrete tiles in place of slate.

Permissions and local rules

Replacement sashes on a scheduled house

What did Enfield require when it permitted replacement sashes?

In April 2020 Enfield granted planning permission at a house in the Vicars Moor Lane Conservation Area, one of those the 2006 Article 4 schedule covers, for timber-framed, double-glazed, double-hung sliding sashes of traditional pattern on the front, side and rear. A condition required 1:20 drawings with 1:5 sections of the new windows, and samples of any new materials, before any above-ground work began. It was a single decision, made on that house’s own facts. It shows the level of detail the council required there, not what it will accept at another house.

Rear extensions and rooflights on the listed terrace

How has Enfield treated an extension to one of the listed Vicars Moor Lane houses?

In March 2020 Enfield refused listed building consent for a single-storey rear extension and loft rooflights at one of the listed houses in the terrace, because, among other reasons, the poor design, scale and siting of the extension and the number and size of the rooflights would fail to preserve the listed building and the conservation area. A revised scheme gained consent in February 2022. The council’s report accepted a single rooflight to a new bedroom, lined up with the first-floor window opening, the approach already taken at two other houses in the terrace.

Digging down beside listed neighbours

What has the council required before a basement here?

When the revised scheme, which included extending the basement, gained consent in February 2022, no basement impact assessment had been submitted. A condition therefore requires one before development starts, covering the excavation, ground conditions, existing infrastructure, construction method and flood risk, to protect the structure of the house and of the adjoining listed houses. Enfield’s 2021 flood risk assessment, evidence for a Local Plan still at examination, not adopted policy, records that some recent groundwater flooding incidents in the borough can be directly linked to the construction of nearby buildings designed on wide, deep strip footings or with basements.

Surface water and the park lake

What does the council’s flood evidence say about this part of Enfield?

The council’s 2012 surface water plan, which is model-based, set out proposals rather than works: alongside investigating the drainage serving the railway cutting at Winchmore Hill, it suggested considering flood resilience measures for properties on River Avenue and Queens Avenue; check the address. Its 2021 flood risk assessment, also evidence rather than policy, lists Grovelands Park Lake, operated by the council, among the reservoirs it counts in the borough, and judges the risk of any reservoir in Enfield failing catastrophically to be sufficiently managed. Neither describes any one home; GOV.UK’s service gives the long-term flood risk for an area.

What the work covers

The work on a Winchmore Hill house, inside and out

Repair first, then renewal

The survey records which sashes, doors, slates, render and weatherboarding are original and what state they are in, so that repair can be weighed against replacement before anything is ordered. Repairs to old fabric use matching materials, lime where lime was used, and careful hand methods where hard render or paint has to come off. Where earlier work stripped details out, the drawings can show what to reinstate, the opportunity the 2015 management proposals describe.

Enfield: Winchmore Hill Green and Vicars Moor Lane Conservation Area Management Proposals, approved February 2015 (PDF)

Stairs, walls and the rooms inside

Inside, the work usually covers the layout, wiring, plumbing and heating, the kitchen and bathrooms, insulation and finishes. In an old house a new staircase or a removed wall changes how loads reach the ground, so the structure is opened up, checked and drawn before anything comes out. Cornices, joinery, fireplaces and floors are recorded first and protected during the work; in a listed house, internal changes that affect its character need listed building consent.

Enfield: listed buildings

The back, the roof and rainwater

At the rear, the job may rebuild an old addition, add an extension or open the ground floor to the garden, and in a terrace or a semi-detached pair the shared walls raise Party Wall questions. On the roof, rooflights are sized and placed with the elevations in mind, gutters and flashings renewed and insulation added with ventilation. Where a planning application is made, Enfield requires householder schemes to follow the minor version of its SuDS pro-forma, so decide early where rainwater will go.

How we work

How we run a Winchmore Hill house refurbishment

  1. Free feasibility visit

    We walk round the house with you and discuss what is feasible.

  2. Survey

    Rooms, levels and features to keep are measured, with opening-up or asbestos checks where needed.

  3. Design and consents

    Our own architects and structural engineers design the layout and structural openings, plan the service routes with them, and identify which consents and party wall notices apply.

  4. Price and contract

    A fixed written price and a JCT contract follow the survey, scope and specification. It records allowances, exclusions and how changes are priced.

  5. On site

    Work is inspected before it is covered, and a director reviews key decisions.

  6. Handover

    Testing, commissioning and snagging. Completed work carries a 12-month defects-rectification period under the JCT contract terms.

Real projects, clearly located

None of these projects is in Winchmore Hill. Each card names where the work was done, so you can judge the finish and the approach before you brief your own.

Your brief

Before you ask for a quotation

  1. Find the house’s designations and history

    Find out whether the house is on the statutory or local list, whether either conservation area includes it and whether it appears in the 2006 Article 4 schedule. Then search the council’s planning register for earlier decisions at the address, since the conditions of an old consent, such as approved window details, can still bear on new work.

  2. List what survives and what has gone

    Walk round the house and note the original sashes, doors, roof coverings, chimneys, render, fireplaces and joinery, and anything replaced in modern materials. Take pictures of every elevation and the main rooms, so the survey can compare what you have with the appraisal’s description of your street.

  3. Say what comes first

    Say which rooms must be ready first, whether you will live at home during the work and which jobs could wait. If a basement, a rear extension or more roof space is part of the plan, mention it now, because those parts can need consents and investigations of their own.

Questions before you begin

House refurbishment in Winchmore Hill: questions

Some council records list my Vicars Moor Lane house under Grange ward. Does that change anything?

Not for planning. Some records made before Enfield’s current wards, which were set by a 2020 order, list one of the listed houses on the lane under the older ward name Grange, and the ward on a planning record is an electoral label from the time, not a planning boundary. The questions that matter are whether the address is in the Vicars Moor Lane Conservation Area, whether it is listed and whether the 2006 Article 4 schedule names it. Check the address against the council’s documents.

Enfield: Find a planning application (the council’s online planning register) · The London Borough of Enfield (Electoral Changes) Order 2020, Schedule · Enfield: Vicars Moor Lane conservation area · Enfield: Enfield Borough Conservation Areas Article 4(2) Direction 2006 (as confirmed), sealed 27 June 2006

Is the big tree in my garden protected?

Possibly. One council record shows that in 2012 and 2013 a yew at a listed house in the Vicars Moor Lane terrace was covered by a Tree Preservation Order, and a crown reduction was applied for as works to a protected tree and granted in January 2013; the record does not show whether the order still applies today. Enfield says pruning, felling or harming a protected tree is a criminal offence unless the work is exempt, so look at its map of orders and ask before work goes near roots or branches.

Enfield: Find a planning application (the council’s online planning register) · Enfield: tree protection and planning

Can I add solar panels or other low-carbon technology?

Enfield’s adopted DMD 53 encourages minor applications to cut carbon further through renewable energy generated on site and low or zero carbon technologies. A separate sentence welcomes local contributions to decentralised energy from such technologies, on condition that no overriding adverse effect on the locality arises, identified effects on historic assets among them. On a listed house, listed building consent applies to works affecting its character, and on a house the 2006 schedule names, check which roof and elevation changes it controls before choosing where panels go.

Enfield: Development Management Document, adopted November 2014 · Enfield: listed buildings · Enfield: Enfield Borough Conservation Areas Article 4(2) Direction 2006 (as confirmed), sealed 27 June 2006

What paperwork should I have when the work is finished?

Keep the building control completion certificate, which Enfield issues once notified work is found satisfactory, with the electrical and gas certificates. The council’s completion notice form also sets out a duty for whoever gave the building notice or made the full plans application: within five days of finishing, they send the notice, on which the client states that the work complies so far as they are aware, and the principal contractor and principal designer confirm they have met their own duties. File any listed building or planning consents, and the details approved under them, alongside.

Enfield: building control applications · Enfield: Regulation 16(4A) completion notice form (PDF)

What tests does Enfield apply to a single-storey rear extension?

Adopted DMD 11 sets several: the extension must not exceed 3 metres beyond the original rear wall of a terraced or semi-detached house, or 4 metres for a detached one. It should be no higher than 3 metres at the eaves, 3.3–3.5 metres at a flat roof’s parapet or 4 metres at a pitched roof’s ridge. Nor may it cross a 45-degree line taken from the mid-point of the nearest original ground-floor window of either neighbour, unless it secures a common alignment of rear extensions, which can justify permitting greater depth.

Enfield: Development Management Document, adopted November 2014

Does a corner house face extra tests for a side extension?

Yes. On a return frontage, the second street-facing side of a corner plot, adopted DMD 14 requires a side extension to stop short of the back edge of the pavement, leaving a gap to its flank wall. Among the policy’s tests, the council weighs that gap against the building line, local character, the extension’s bulk, visibility splays and the amenity space left. A listed house, or one in either conservation area, adds other consents and policies, so settle them before the design is fixed.

Enfield: Development Management Document, adopted November 2014

How much does a house refurbishment cost in Winchmore Hill?

It depends on scope. In Winchmore Hill, a cosmetic refurbishment keeping the existing layout runs £650–£1,250/sqm (typically £90,000–£180,000); a back-to-brick renovation runs £2,250–£3,250/sqm (typically £275,000–£475,000), excluding VAT. A written scope and site assessment come before any fixed price.
