St John's Wood was London's first suburban development of villas, and about 470 of its buildings are listed; restoring one starts with what survives.
Control
Westminster's mini guide describes St John's Wood as the earliest suburban housing in inner London, laid out mainly on Eyre family land during the 1820s and 1830s.
Around 470 buildings in the conservation area are on the statutory list, by the same guide's count.

Stucco, stock brick and classical detail
The earlier Italianate villas were mostly fully stucco rendered with simple classical detailing, the 2008 audit says.
The widespread use of yellow stock brick and stucco gives most of the conservation area a coherent character.
Restoring a stucco front means repairing cracks and detached render in a compatible lime mix, renewing mouldings from surviving sections, and repainting in breathable paint once the render has dried.

Recording the house before work starts
Before anything is taken out, we photograph and measure each room, number the joinery and note which plaster, floors and fittings are original and which are later. That record goes into the heritage statement and stays with the house afterwards.
Opening-up is done in a few small, agreed places, so the state of hidden timbers and the extent of earlier alterations are known before the scheme is fixed and priced.
Cornices, ceilings and lime plaster
Ceilings in the villas are usually lime plaster on timber laths, often with a run cornice and a centre rose. Where a ceiling has sagged, we fix it back to the joists with plaster washers and repair it in lime, rather than pulling it down and boarding over.
Missing lengths of cornice are run in place with a profile cut from a surviving section, and enrichments are cast from moulds taken off the original work in the same room.
Sash windows and doors
Windows on the terraces and classical villas tend to be single glazed, double-hung timber vertical sliding sashes, the audit says.
Where wholesale replacement is unavoidable, doors and windows should match the originals in glazing pattern and opening method.
Most sashes can be repaired: we splice new timber into sills and rails, renew cords and weights, and keep the old glass where it survives.

Listed building consent and Policy 44
Policy 44 of the City Plan protects a listed building's special interest: original and significant fabric is kept and, where that suits the building, put back.
Westminster has more than 11,000 listed buildings and structures, over 200 of them Grade I.
Section 7 of the Planning (Listed Buildings and Conservation Areas) Act 1990 makes consent necessary for any alteration or extension that affects a listed building's character.
We record a listed room's plan, joinery and plasterwork before work starts, and propose repairs in matching materials and methods.

Floorboards, stairs and panelled doors
Original boards are lifted only where services have to pass, numbered as they come up and relaid in the same place. A worn stair can be kept by piecing new timber into the treads and nosings, with the balusters and handrail left where they are.
Panelled doors are eased and rehung, and stripped only where layers of paint have filled their mouldings. Original ironmongery is cleaned and refitted; where pieces are missing, we match them from a surviving door.
Chimneypieces and the flues behind them
Marble and timber chimneypieces stay in place, protected, unless the wall behind needs repair. Before a fire is lit again, the flue is swept and inspected, and a liner is fitted only if the inspection shows one is needed.
Where a later owner blocked a fireplace, we open it carefully to see what survives of the grate and the hearth before proposing how to reinstate it.
New services without cutting old fabric
Rewiring and new plumbing are planned around the building rather than through it: along the joists under the boards, behind skirtings and in the voids beside chimney breasts. Cables are not chased into decorative plaster, and pipe runs are set out so no historic floor is cut twice.
Electrical and gas work is carried out by appropriately registered engineers.
Roofs and chimneys
Westminster's audit wants the original slates and tiles saved whenever a roof is stripped, with salvaged covering put back on the slopes people can see.
The same audit warns that roof additions would, in many cases, harm the area too much to be accepted.
Restoring a roof also means repairing lead valleys and flashings, cast-iron gutters and the tall stacks, all while one scaffold is up. New slates, where they are needed, are matched for size, colour and thickness.

Front walls, gate piers and forecourts
Front boundaries are most commonly painted stucco or brick walls with tall gate piers topped by a simple capping, the audit records.
Additional forecourt parking will be resisted, and where hardstanding exists Westminster will encourage more planting.
Restoring a front wall means rebuilding the piers to their original height and capping, and repairing the stucco or brick to match.

Paint, render and colour on the front
Stucco fronts are repainted in a breathable masonry paint once the render has been repaired and allowed to dry. Where a villa is one of a pair or a group, the colour should match its neighbours, so we put up sample panels for you, and the council where needed, to see in daylight.
Stock brick is cleaned gently, if at all, and repointed in a lime mortar that matches the old joints in colour, texture and profile.
Railings, balconies and ironwork
Cast-iron railings, balcony fronts and the brackets under them rust from the fixings outward. We take damaged lengths to a foundry for repair, cast missing pieces from a surviving section, and reset the bases in lead or a suitable mortar so water cannot collect where the iron meets the stone.
Before repainting, old paint is taken back to sound metal, primed and finished in a traditional colour agreed for the group of houses, not chosen for one front alone.
Making an old house warmer without harming it
Draught-proofing the sashes, fitting slim secondary glazing inside the original windows and insulating under the ground floor from the basement side can make a period house noticeably warmer while leaving its fabric alone.
We use breathable materials such as wood fibre and lime against old walls, because a vapour-tight lining can trap moisture in solid brick, and we check any change to a listed building with the council first.
Mansion blocks and their common parts
Mansion and flat blocks from the Victorian, Edwardian and interwar years are part of the area's character, particularly on Wellington and Circus Roads.
Depending on the lease, a leaseholder may need the landlord's permission before any alteration, LEASE advises.
Restoring a flat in one of these blocks often means working with the managing agent on the entrance, stair and windows that belong to the building as well as on the rooms inside. We agree what is the leaseholder's and what is the landlord's before the work is priced.

Protected squares and the Abbey Gardens direction
Alma Square and the Park Road triangle are both protected under the London Squares Act 1931, Westminster's mini guide notes.
On Abbey Gardens, the odd numbers 1 to 47 and the even numbers 2 to 56 sit under an Article 4 direction covering changes to the elevations they show the street.
Work on a house facing one of these spaces is planned with its setting in mind, from scaffold position to the colour of the repainted front.

What helps us advise on a listed house
Photographs of each main room and of the front and back, the list entry if the house is listed, and any earlier consents or surveys make the first visit far more useful. If works were done before you bought the house, tell us what you know: unauthorised changes affect what can be put right and how.
We then visit with one of our architects and set out what needs consent, what is ordinary repair, and the order in which the work should happen.
Vaults, scaffolds and working hours
Pavement vaults and other structures below the path are checked before a skip or heavy machine is set down over them, as Westminster's Code requires.
A scaffold, hoarding or fence on the pavement, and any skip in the road, each needs its own licence from the council beforehand.
Noisy restoration work keeps to Westminster's hours: weekdays from 8am until 6pm, Saturdays from 8am until 1pm, and never on Sundays or bank holidays without permission.

Questions about heritage restoration in St John's Wood
How many listed buildings are there in St John's Wood?
Westminster's 2004 mini guide counts some 470 in the conservation area.
Do I need listed building consent to restore my house?
For alterations that affect its character, yes, under section 7 of the 1990 Act; Policy 44 asks that original fabric is protected.
Should my sash windows be replaced?
Repair first; where wholesale replacement is unavoidable, new ones should match the originals' glazing and opening.
Will my roof be re-covered in new slate?
Only where the old slates cannot be saved: Westminster's audit asks for originals to be refixed, ideally where they can be seen.
Can I park in my front garden?
Additional forecourt parking will be resisted, and where hardstanding exists Westminster encourages more planting.
What does heritage restoration in St John's Wood cost?
Pricing: quoted after a feasibility visit.

What our clients say about working with our heritage team on their listed and period properties.
Our Georgian townhouse in Hampstead had been badly treated by previous owners. The heritage team stripped everything back with extraordinary care, rebuilt the cornicing from fragments they found in the attic, and restored every sash window. The conservation officer actually complimented the quality of the heritage statement — that never happens.
We were terrified of getting listed building consent for our kitchen extension in Canonbury. Hampstead Renovations handled the entire process — the heritage impact assessment, the meetings with Islington's conservation team, and the design itself. Approved without amendments. The builders clearly knew how to work alongside old fabric without damaging it.
The lime plasterers on this team are genuinely exceptional. They matched 200-year-old moulding profiles by hand-running new sections from templates they made on site. The level of craftsmanship is something you simply don't find with standard builders — these people understand historic buildings in a way that gives you complete confidence.
