Mary Poppins
17 Cherry Tree Lane, London
This address isn't real. We pinned Cherry Tree Lane to Hampstead, NW3 — the area facts are true to that corner of Camden, the street-level figures are illustrative. Everything below is the £1.99 report.

High ground, clean air, an 800-acre heath and a major teaching hospital half a mile away. Schools are exceptional and the streets are genuinely quiet. Everything about it is excellent and everything about it is expensive, including the parts you cannot change.
- Hampstead Heath a few minutes away — 800 acres, swimming ponds, and the best kite ground in London.
- The Royal Free runs a 24-hour A&E about half a mile from the door.
- Some of the cleanest air in inner London, well inside legal limits.
- Outstanding primaries within a mile and one of the densest concentrations of schools in the country.
- Typical sale around £2,850,000, and flat to slightly down since 2022.
- A house this size is Band G or H — roughly £3,500 to £4,200, not the £2,100 headline.
- Conservation area and likely listing: windows, roof and chimneys all become long arguments.
- Residential burglary runs above average, which is the standard pattern for large houses up here.
Day to day this is one of the pleasantest addresses in London: quiet streets, clean air, a hospital and a heath both within a walk, and a tube that will have you in the City inside half an hour once you have dealt with the lift. Budget for the band rather than the headline council tax, expect to ask permission before changing anything anyone can see, and take something up the hill before you commit — every journey home from here is a climb.
Environment & risk
Hampstead is one of the highest points in London and sheds water rather than collecting it. No river risk, negligible surface water. The Fleet is a problem at the bottom of the hill, not the top.
Below the London average overall, with violence low. Burglary is the exception and runs above average — the usual pattern for large houses with long garden backs. One persistent report concerns a woman letting herself in at first-floor level.
Among the cleanest air in inner London — height, tree cover, 800 acres of heath. The local particulate source is domestic: working fireplaces on a still evening. This house runs several flues, and the men who clear them are often on the roofline.
London clay and sand, lowest band. No testing or remedial work is expected on a house here.
The streets up here carry very little through traffic — narrow, steep, and going nowhere useful, which is the best noise protection there is. The loudest thing on this street is reliably the household itself, usually before nine.
North London sits under holding routes but at considerable altitude — nothing like the Heathrow stream to the west. Helicopters are the more frequent interruption.
The Northern line runs beneath at exceptional depth — Hampstead is the deepest station on the Underground, around 58 metres — so there is no surface running and nothing audible.
Inner-London distribution is entirely underground. No pylons, no overhead lines, and nothing in the view but a conservation area and a great deal of sky.
Mostly conservation area with much of the housing listed, so very little will be built near you that you would not want. The same applies to your own house — expect a long argument over windows, roof lights and chimney stacks.
About 60 miles from open coast, so nothing to report — we run the check anyway. The only weather this household treats as a transport option arrives from the east, and appears in no dataset we hold.
Connectivity
Gigabit full fibre from more than one network. The constraint is internal: five storeys of solid Victorian masonry defeats a single router, and conservation rules make external cabling a conversation rather than a job.
Four-network coverage outdoors and generally strong, but thick period walls take more off indoors than the readings suggest, and the tube here is deep enough to lose everything. Wi-Fi calling is the practical answer.
Health & education
Several Outstanding primaries within a mile, strong state secondaries in reach, and one of the densest concentrations of independent schools in the country. Catchments are measured in hundreds of metres. Households here have historically preferred to educate at home with hired help.
Three practices within a mile, two an easy walk, all taking new patients at the last check. Waits are around the London average.
Several within a short walk on the high street and in South End Green, with late opening between them, and the hospital close enough for anything urgent.
The Royal Free runs a 24-hour A&E about half a mile away — genuinely walkable. A major teaching hospital this close is unusual. Nothing here has yet been needed for a fall from a bannister, which given this staircase is luck.
Around ten practices within a mile. NHS books for new adult patients are effectively shut, which is national rather than local. Private provision is abundant and priced for the postcode.
Around fifteen nurseries and pre-schools within a mile, a high proportion Good or Outstanding, plus a deep local market in nannies. This postcode has employed live-in childcare for well over a century. Fees are among the highest in the country.
Lifestyle
Three within a ten-minute walk, including a large one on the edge of the Heath with a summer paddling pool. The open space behind is effectively unlimited — just as well, since the children here are walked out daily whatever the weather.
A full-size supermarket within a mile and a dense run of delicatessens, butchers and greengrocers on the high street — genuinely good, and priced accordingly. Shopping locally costs noticeably more than two miles south.
Hampstead Heath is minutes away: 800 acres of woodland, meadow and pond, with swimming ponds, a lido and the view from Parliament Hill. It is also the best kite-flying ground in the city — high, open and reliably windy.
The Heath gives genuine off-road running with real climbs — rare inside a capital — plus a Saturday parkrun and paths you could run for a year without repeating. If you run, this is among the best addresses in London.
Around sixty food businesses within a mile, weighted to restaurants and cafés rather than fast food. Quality high, range narrower than more mixed parts of London, and a Hampstead premium on the bill.
Around a dozen within a mile, well below the London average — high rents, conservation frontages and a planning authority that has not been keen. Delivery covers the area regardless.
Around twelve within a mile, including some of the oldest and best-known in London, several with gardens. The traditional destination for a man who has had a difficult afternoon at the bank.
Four within a mile, well below the London average. This is a postcode of appointment-only salons rather than walk-in chairs, and the price difference is roughly fourfold.
Two within a mile, both on the busier shopping stretch. Well below the London average — local rents and the planning committee have between them kept the number down.
Eight or so within a mile, weighted to the boutique end. The real assets are outdoors: the mixed and single-sex swimming ponds, open year round, and the lido across the Heath.
A Post Office within a short walk handles the banking basics, and — unusually for 2026 — two branches remain within a mile. This household has always had strong views about a bank continuing to exist, and here one does.
Three practices within a mile and 24-hour emergency cover about ten minutes away. Busy, in a postcode with this many dogs and a Heath to walk them on. Nobody has yet presented a bird; they manage unattended, tuppence a bag.
Two Camden libraries within a mile with full hours, study space, public computers and children’s sessions. Camden has protected its library service better than most.
A large leisure centre with a main pool, teaching pool, gym and courts about a mile south, with the lido and the ponds as the outdoor alternative.
Two sites within a mile and a half, both with waiting lists running to years. Most houses on a street like this have a garden that makes the question academic.
Camden’s reuse and recycling centre is roughly fifteen minutes away, booking advised at weekends. Narrow streets and residents parking make bulky waste an exercise in planning.
People & community
Outright ownership is unusually high here — age and wealth rather than mortgages — with private renting close behind and social renting well below the London average. One of the least mixed tenure profiles in Camden.
On every dimension the Census measures this area sits in the least deprived decile nationally. Camden as a whole is far more mixed — you do not have to walk far downhill to find otherwise.
Camden accommodates people under Home Office dispersal arrangements, but overwhelmingly elsewhere in the borough — dispersal follows cheap rents, and there are none here. Nothing contracted on this street. We report it because people ask.
Cost & property
Camden charges around £2,100 at Band D, but a house this size sits at Band G or H — £3,500 to £4,200. Do the arithmetic on the actual band. A household running to staff will note the bill does not scale with occupants.
Three sales on this postcode in five years, £2,150,000 to £3,600,000. The Camden average is around £820,000, which mainly tells you Camden contains a great many flats and this street is not one of them.
Transport
Five routes stop within about five minutes, reasonably frequent, with a night service on two. Fewer than lower down the hill, which is the trade for the quiet.
Hampstead station is a short walk — the City in twenty minutes, the West End in twelve — though it is the deepest on the network, so allow for the lift. A street built for men who must be at a bank by nine.
A controlled zone operates on weekdays and a permit is required. The streets are narrow and the spaces tight, though a proportion of houses have their own frontage. Heath visitors make weekends noticeably worse.
Two active or imminent works within a quarter-mile, both short utility jobs — low for London. Narrow streets mean each one closes a road rather than a lane, so disruption per job is higher.
More than twenty public charge points within a mile, including lamp-post charging nearby. Installing your own on a listed or conservation frontage is a planning question rather than an electrical one.
Two filling stations within a mile and a half, both with shops. Prices a few pence above the national average, as across inner London.
Camden has built good segregated routes, but the obstacle here is topography: every journey home is uphill, steeply. Electric assistance is not an indulgence. The alternative methods available to this household are not ones we can model.
Council & MP
Camden is a unitary authority, so bins, planning, schools and council tax all come from one place. Much of this area is a conservation area, so Camden is also a party to most decisions about your own windows.
Tulip Siddiq has represented this area since 2015, and Hampstead and Highgate in its current form since July 2024. Employment disputes arising from a domestic staffing arrangement are, regrettably, a matter for a tribunal rather than an MP.
