Buying property in Mayfair: a buyer’s guide
Mayfair is the most expensive square mile in London and, for the buyer who wants to walk to everything, the most convenient. Bounded by Hyde Park, Piccadilly, Regent Street and Oxford Street, it combines the grandest Georgian streets in the capital with its best hotels, restaurants, galleries and clubs. It is also a small, idiosyncratic market where the difference between two houses fifty metres apart can be a third of the price. I have developed and bought here for twenty years, and it still rewards care.
What is Mayfair like to live in?
Quieter than its reputation. The main thoroughfares are busy, but the streets between them, particularly the grid around Mount Street, Farm Street and the mews behind them, are residential and calm in the evenings. Mount Street is the village high street, if a village high street sold Italian shoes and lobster. Shepherd Market, a few minutes south, has kept a pleasantly scruffy character. Berkeley Square and Grosvenor Square are the two great public spaces, and Green Park and Hyde Park are on the doorstep.
Residents are a mix of long-established British families, international owners who use the property for part of the year, financiers whose offices are within walking distance, and a younger cohort who value being able to walk to dinner. The private members’ clubs, the commercial art galleries and a large concentration of the city’s best restaurants make it the only district in London where a resident can genuinely live without needing to travel anywhere else.
Which parts of Mayfair should a buyer look at?
Mayfair Village, the streets around Mount Street and Grosvenor Square, is the traditional heart and remains the most sought after. The ground here is owned largely by the Grosvenor Estate, which has kept its streets coherent and has spent heavily on the public realm. Its reputation for careful management is deserved and its consent will be needed for most alterations.
Further south, the streets between Curzon Street and Piccadilly, including Half Moon Street, Charles Street and the squares off them, have a slightly more relaxed feel and a good stock of Georgian houses and period apartments. North Mayfair, towards Oxford Street, was historically the less fashionable end; the arrival of the Elizabeth line at Bond Street, with a direct connection to Heathrow, has changed that for international buyers who travel constantly.
The finest houses are on the streets that still read as Georgian: Park Street, Upper Brook Street, Charles Street and Hill Street among them. Our own development at Park Street, a Georgian house acquired for £2.9m, extended and sold for £6.8m, is a reasonable illustration of what the best of these streets can support and of the value that skilled work adds to them.
What types of property are there?
Mayfair has four broad categories. Georgian and later townhouses, many listed, some still single dwellings and many converted to lateral apartments. Mansion blocks, red brick and often portered, offering the large lateral flats that international buyers favour. New-build and branded residences, where the price per square foot is highest and the service is hotel-grade. And mews houses, tucked behind the main streets, which give privacy, a garage and no through traffic.
Each behaves differently as a purchase. A listed townhouse brings restrictions on works and a maintenance obligation that must be understood before offering. A mansion-block flat brings a lease, a service charge and a residents’ company whose finances need reading. A branded residence brings the highest running costs in London and the smallest room for negotiation on those costs. A mews house is often the best value per square foot and the easiest to run.
What do Mayfair prices look like?
Mayfair has outperformed the rest of prime central London over the past decade, partly because new schemes at the top of the market pulled the average up and partly because it is the district international buyers name first. Average sale prices sit around £2,000 per sq ft, and the best lateral apartments on Grosvenor Square or in the branded schemes trade at several multiples of that. A well-located period flat in reasonable condition can still be found for less, and a house in need of work less again, which is where a buyer with the appetite for a project finds value.
Two cautions. The spread between asking and achieved prices in Mayfair is wide, because vendors here are rarely in a hurry and asking prices are often aspirational; our own average across acquisitions is 12% below asking, and Mayfair contributes to that figure. And leasehold matters more here than almost anywhere, because so much of the freehold sits with the great estates. A flat with sixty years left on its lease is a different asset from one with a hundred and twenty.
What should a buyer check before offering?
The lease, first: its length, the ground rent, the alterations clause and the landlord’s track record on consent. The service charge accounts for the last three years and any planned major works. Listing status and the planning history, including whether previous owners obtained consent for what they did. The building’s other occupants, because a townhouse conversion with a nightclub on the ground floor is a different proposition from one with a private bank. Noise from restaurant extraction and delivery vehicles on the streets around Mount Street. And, for the branded residences, exactly what the service charge buys and how it has moved since completion.
Then the market evidence. Very few Mayfair transactions are advertised. A good proportion of the best sales, particularly houses and large laterals, are done privately, and the comparable evidence a buyer needs is not on the portals. Knowing what a neighbouring flat in the same block sold for last year, and in what condition, is the difference between a good offer and a guess.
How do homes in Mayfair actually change hands?
Quietly. Vendors in Mayfair have privacy to protect, and their agents know that a discreet call to a handful of proceedable buyers will usually achieve the price. A buyer who relies on the portals sees the properties that failed to sell that way. Across our acquisitions since 2006, 78% have been secured off-market, and in Mayfair I would put the figure higher.
The other route is the direct approach, asking the owner of a house that is not for sale whether they would consider a price. It sounds presumptuous. It is how we secured 16 Old Bond Street for Prada in 2013, when the building was not on the market, and it works for houses as well as shops. Owners of the best Mayfair properties are approached regularly; the ones who say yes say it to people they trust.
How Arbitrage can help
We have bought and developed in Mayfair for twenty years, from Park Street to Conduit Street, and we know its buildings, its freeholders and its private market. We act only for buyers, we find most of what we buy before it is advertised, and we negotiate from evidence rather than the asking price. Our office is a short walk away in Covent Garden.
Frequently asked questions
Is Mayfair a good place to live or only to invest?
Both, but it suits a particular kind of resident: someone who values being able to walk to dinner, to the office and to the park, and who is comfortable in a district that is busy by day. Families with young children tend to prefer Kensington, Chelsea or St John’s Wood for space and schools; Mayfair suits couples, single occupiers and those who use London for part of the year.
Are branded residences in Mayfair worth the premium?
For an owner who wants hotel service and will use it, and who is untroubled by the highest service charges in London, they can be. As an investment they are less certain, because the premium is priced in at purchase and the running costs weigh on both yield and resale. Compare the price per sq ft with the best mansion-block laterals before deciding.
How much of Mayfair is leasehold?
Most flats and many houses. Large parts of the district sit on the Grosvenor Estate and other historic freeholds, so lease length, ground rent and the freeholder’s approach to consents are central to value. Always have the lease read by a solicitor experienced in prime central London before offering.
Can I extend or alter a Mayfair townhouse?
Often, but with more constraints than elsewhere. Listed status, conservation-area rules and the freeholder’s alterations clause all apply, and basement excavation is closely controlled. Establish what consent is realistically obtainable before you rely on it in the price.
