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 sits on one of the highest points in London, well over 100 metres up, and the ground here sheds water rather than collecting it. No river flood risk and negligible surface water. The Fleet rises on the Heath and runs south in a culvert, which is a problem for people at the bottom of the hill rather than anyone at the top of it. The nursery is on the top floor regardless, which settles the question for this household.
Total recorded crime sits below the London average and violent crime is low. Residential burglary is the exception and runs above average, which is the standard pattern for a wealthy, low-density area with large houses and long garden backs. Nothing about the street feels unsafe; the risk here is to the contents rather than to you. The one persistent local report concerns a woman letting herself in at first-floor level, which the responding officers were unable to write up satisfactorily.
Nitrogen dioxide sits comfortably within limits and well below the inner-London norm — height, tree cover and 800 acres of heath will do that. Finchley Road is the one corridor that pulls the numbers up, and it is far enough away not to matter here. The main local source of particulates is domestic: a street of period houses with working fireplaces, on a cold still evening, produces more smoke than the traffic does. A house of this size runs several flues, and the men who keep them clear are on the roofline here more often than anywhere else in the borough.
London clay and sand, lowest band. No testing or remedial work is expected on a house here.
The residential streets up here carry very little through traffic — they are narrow, they climb, and they do not go anywhere useful, which is the best noise protection a street can have. Finchley Road and the South End Green junction are the busy points and neither is close enough to be heard from the house. The loudest thing on this street is reliably the household itself, and usually before nine in the morning.
North London sits under holding and approach routes but at considerable altitude — nothing like the Heathrow arrival stream to the west. You will hear aircraft on a still evening and otherwise not register them. Helicopters are the more frequent interruption.
The Northern line runs beneath this area at exceptional depth — Hampstead is the deepest station on the Underground, around 58 metres down — so there is no surface running and no audible vibration. Overground services through Hampstead Heath and Finchley Road are far enough off to be irrelevant here.
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.
Most of this area is a conservation area and a good proportion of the housing is listed, so the surroundings are about as protected as English planning allows — very little will be built near you that you would not want. The same protection applies to your own house: expect a long, expensive and closely argued process for anything visible from the street, including windows, roof lights and the chimney stacks. Basement schemes are the live local controversy.
About 60 miles from open coast, so there is no erosion picture to report. We still run the check on every address rather than quietly dropping it, so you can see it came back clear rather than wonder where it went. The only weather this household treats as a transport option arrives from the east and does not appear in any dataset we hold.
Connectivity
Gigabit full fibre is available at this postcode from more than one network. The constraint in a house of this type is internal rather than external: four or five storeys of solid Victorian masonry defeats a single router comprehensively, and conservation-area rules make external cabling a conversation rather than a job.
Four-network coverage outdoors and generally strong, but indoor signal in a thick-walled period house is noticeably worse than the outdoor readings suggest, and the tube here is deep enough that you lose everything on the platform. Wi-Fi calling is the practical answer and most households up here use it.
Health & education
Several Outstanding primaries within a mile and some of the strongest state secondaries in London within reach, alongside a concentration of independent schools that is among the densest in the country. Competition is fierce and catchments are measured in hundreds of metres. This is a genuine strength of the address and priced into it. Households up here have historically preferred to educate at home with hired help, which is a considerably less predictable arrangement than a catchment.
Three GP practices within a mile, two within an easy walk, and all taking new patients from this postcode at the last check. Waits are around the London average.
Several pharmacies within a short walk on the high street and in South End Green, with late opening between them, and the hospital below is close enough to cover anything urgent out of hours.
The Royal Free runs a full 24-hour A&E and is roughly half a mile away — genuinely walkable, and a few minutes by car. Having a major teaching hospital this close is unusual and is one of the strongest lines in this report. It is also the reason for the ambulance traffic on the approach roads. Nothing here has ever been needed for a fall from a bannister, which in a house with this staircase is a matter of some luck.
Around ten practices within a mile. NHS availability for new adult patients is effectively nil, which is the national picture rather than a local one. Private provision is abundant and priced for the postcode.
Around fifteen nurseries and pre-schools within a mile, a high proportion rated Good or Outstanding, plus a deep local market in nannies and childminders — this postcode has employed live-in childcare for well over a century and the infrastructure reflects it. Full-time fees are among the highest in the country.
Lifestyle
Three playgrounds within a ten-minute walk, including a large one on the edge of the Heath with equipment across the age range and a paddling pool in summer. Provision here is excellent and the open space behind it is effectively unlimited — which is just as well, since the children on this street are walked out daily whatever the weather is doing.
A full-size supermarket within a mile and a dense run of delicatessens, butchers, bakers and greengrocers on the high street — genuinely good, and priced accordingly. A weekly shop done entirely locally will cost you noticeably more than the same basket two miles south.
Hampstead Heath is a few minutes away: around 800 acres of unmanicured woodland, meadow and pond, with swimming ponds, a lido, and one of the best views in London from Parliament Hill. It is also the best kite-flying ground in the city, being high, open and reliably windy. On green space this address is not merely good, it is close to the national ceiling.
The Heath gives you genuine off-road running with real climbs — rare inside a capital city — plus a Saturday parkrun and a network of paths you could run for a year without repeating. The Parkland Walk connects onward to the north-east. If you run, this is among the best addresses in London. The Heath is also the local kite ground, being high, open and reliably windy, and on a Saturday the sky above Parliament Hill is busier than the paths below it.
Around sixty food businesses within a mile, weighted heavily toward restaurants and cafés rather than fast food. Quality is high, range is narrower than in more mixed parts of London, and the bill arrives with a Hampstead premium attached.
Around a dozen takeaways within a mile, well below the London average — a function of high rents, conservation-area frontages and a planning authority that has not been keen. Delivery platforms cover the area regardless.
Around twelve pubs within a mile, including some of the oldest and best-known in London, several with gardens and one or two that have been serving since long before anyone on this street had staff. Excellent on this measure, and the traditional destination for a man who has had a difficult afternoon at the bank.
Four within a mile, which is well below the London average. This is a postcode of appointment-only salons rather than walk-in chairs, and the price difference between the two is roughly fourfold.
Two within a mile, both on the busier shopping stretch. Well below the London average — the local planning committee and the local rents have between them kept the number down.
Eight or so gyms and studios within a mile, weighted toward the boutique end. The real assets are outdoors: the mixed and single-sex swimming ponds, open year round to anyone prepared for them, and the lido on the far side of the Heath.
A Post Office within a short walk handling the usual banking basics, and — unusually for 2026 — two bank branches remaining within a mile. The household at this address has historically had strong views about the importance of a bank continuing to exist, and on this street it still does.
Three veterinary practices within a mile and 24-hour emergency provision about ten minutes away. Good coverage, and busy — this is a postcode with a very high dog population and a Heath to walk them on. Nobody locally has yet presented a bird, though the woman who feeds them on the cathedral steps would tell you they manage perfectly well unattended.
Two Camden libraries within a mile with full opening hours, study space, public computers and children’s sessions during the week. Camden has protected its library service better than most and it shows.
A large leisure centre with a main pool, teaching pool, gym and courts sits about a mile south, with the lido and the ponds as the outdoor alternative. Provision is comfortably above what most London postcodes manage.
Two allotment sites within a mile and a half, both with waiting lists running to several years. Standard for inner London, and made worse here by how many people want one. Most houses on a street like this have a garden that makes the question academic.
Camden residents get a reuse and recycling centre roughly fifteen minutes away, taking the usual household range, with booking advised at weekends. Kerbside collection covers the day to day. Narrow streets and residents parking make bulky waste an exercise in planning.
People & community
Outright ownership is unusually high here — a function of age and wealth rather than of mortgages — with private renting close behind and social renting well below the London average. This is one of the least mixed tenure profiles in Camden, which is a borough that elsewhere mixes very thoroughly indeed.
On every dimension the Census measures — employment, education, health and housing — this area sits in the least deprived decile nationally. Camden as a whole is far more mixed, and you do not have to walk very far downhill to find neighbourhoods with an entirely different profile.
Camden accommodates people under Home Office dispersal arrangements, but the housing used is overwhelmingly in other parts of the borough — dispersal follows cheap rents, and there are none here. There is no contracted accommodation on this street. We report it because people ask, and because it says something about a place either way.
Cost & property
Camden charges a little under the England average at Band D, around £2,100 including the Greater London Authority precept. A house of this size will sit at Band G or H, where the bill runs to roughly £3,500 to £4,200. Worth doing the arithmetic on the actual band rather than the headline figure, because the gap between them here is larger than in most places. A household running to staff should note that the bill does not scale with the number of people in the house, which is the only line in this report that works in its favour.
Three sales recorded on this postcode in the last five years, from £2,150,000 to £3,600,000. Across Camden the average price is around £820,000, which tells you mainly that Camden contains a great many flats and that this street is not representative of it. Prices at this end of the market have been flat to slightly down since 2022.
Transport
Five bus routes stop within about five minutes, with reasonable frequency across the day and a night service on two. Fewer routes than you would get lower down the hill, which is the trade for the quiet.
Hampstead station is a short walk and puts the Northern line at your disposal — the City in around twenty minutes, the West End in twelve. It is also the deepest station on the network, so allow for the lift rather than the escalator, and allow more of your life for it than you expect. Hampstead Heath adds Overground services east and west. The City is the point of all of it: this is a street built for men who need to be at a bank by nine and home by six.
A controlled parking zone operates on weekdays and a resident permit is required. The streets are narrow and Victorian and the spaces are correspondingly tight, though a proportion of houses of this type have their own frontage or a garage, which changes the picture entirely. Weekend visitors to the Heath make Saturday and Sunday noticeably worse than weekdays.
Two active or imminent street works within a quarter-mile, both short utility jobs. Low for London. Narrow streets mean any one of them closes a road rather than a lane, so the disruption per job is higher than the count suggests.
More than twenty public charge points within a mile, including lamp-post charging on several residential streets. Camden was early to that. Installing your own point on a listed or conservation-area frontage is a planning question rather than an electrical one.
Two filling stations within a mile and a half, both with shops attached. Prices run a few pence above the national average, as they do across inner London.
Camden has built good segregated routes across much of the borough and there are quiet-street links toward the centre. The obstacle here is topography rather than infrastructure: every journey home is uphill, and steeply so. Electric assistance is not an indulgence at this address. The alternative methods of getting up the hill available to this household are not ones we can model.
Council & MP
One council does everything here: Camden is a unitary authority, so bins, planning, schools, social care and the council tax bill all come from the same place. Much of this area is a conservation area, which means Camden is also, in practice, a party to most decisions you might want to make about your own windows. Policing is the Metropolitan Police.
Tulip Siddiq has represented this area since 2015, and Hampstead and Highgate in its current form since July 2024. This is who writes back if you take a local issue — a planning refusal, a school place, a hospital waiting list — as far as Westminster. Employment disputes arising from a domestic staffing arrangement are, regrettably, a matter for a tribunal rather than for an MP.
