How to read this page. Prices are asking or guide prices, not achieved prices — in
this market the two frequently differ. Price per square foot is our own calculation from the
published floor area. The all-in figure assumes a non-UK-resident buyer who already owns
residential property elsewhere, and includes SDLT, our 5% commission, and £31,000
of legal, survey and disbursement costs — it is what the purchase actually costs, end to end. Lease length is stated wherever the marketing agent publishes it, including where it
is a problem. Each property is marketed by the agency named against it.
Knightsbridge
SW1X · SW7
Fourteen properties in band and twelve within reach once tax and fees are counted — more than the
other two areas combined — at the lowest median of the three, £2,348 per square foot. The strongest
negotiating position, and where we would start.

Knightsbridge
Hans Place, London SW1X
A penthouse arranged across the third and fourth floors of
an elegant red-brick period building on one of Knightsbridge's finest garden squares. Principal
bedroom suite with dressing area and study, three further en-suite bedrooms, two reception rooms
and air conditioning throughout. On our numbers the best combination of price per square foot and
lease length currently available in the area.

Knightsbridge
Lancelot Place, London SW7
A lateral apartment of 2,731 square feet in a modern
service-led building on a quiet cul-de-sac in the centre of Knightsbridge, moments from Hyde Park
and Harrods. Full building services and porterage — the practical counterpoint to period stock,
and the largest apartment in our Knightsbridge selection.

Knightsbridge
Cadogan Square, London SW1X
A lateral apartment on one of London's most prestigious
garden squares, with reception room with triple windows, integrated kitchen and three bedrooms.
We include this as a caution rather than a recommendation. At £3,785 per square
foot it is the most expensive apartment in our entire survey, and its 86-year lease is the
shortest — below roughly 80 years, marriage value applies and extension costs rise sharply. It
should be valued net of the cost of a statutory lease extension.

Belgravia
SW1X · SW1W
Six properties in band, five within reach — but the strongest tenure profile of the three areas — long leases are the norm, and the only freehold in our survey is
here.
45 Eaton Square, London SW1W
A fourth-floor penthouse on Eaton Square itself — the
address that defines Belgravia. Three double bedrooms, three bathrooms, a modern fitted kitchen
and two interlinking reception rooms giving substantial entertaining space. Lift, concierge,
balcony, access to the communal gardens, resident parking, and 24-hour security provided by the
Grosvenor Estate team. Sloane Square is a short walk.

Wilton Crescent, Belgravia SW1X
A duplex apartment on one of Belgravia's most sought-after
crescents, with two reception rooms, a modern kitchen and access to the communal gardens close to
Hyde Park. At 189 years, the longest conventional lease in our Belgravia selection, and 2,545

Belgravia · Freehold house
Chapel Street, London SW1X
A freehold townhouse of 3,756 square feet
on Belgravia's eastern edge, near Knightsbridge shopping and Hyde Park. At £1,597 per square foot
this is the best value of any property in our survey by a wide margin, and the only one with no
lease to extend, ever. It is a house rather than an apartment — but for a purchaser willing to
consider one, nothing else in this band competes on ownership terms.

Mayfair
W1K · W1J
Only five properties sit in this band in Mayfair, and just four are affordable all-in. Highest international recognition and the strongest resale, but too thin now for a systematic
search — worth acquiring if the right single property appears.
Six Charles Street, Mayfair W1J
A newly developed residence in a building dating to 1849,
near Berkeley Square, with interiors styled by 1508 London. Secure underground parking, concierge,
underfloor heating, comfort cooling and 1000Mbps broadband, with access via the main entrance or a
private door on Hay's Mews. The 998-year lease is effectively freehold — the strongest tenure of
any apartment in our survey.

Park Street, Mayfair W1K
A beautifully presented lateral flat on the fourth floor,
with four bathrooms, two reception rooms and a study, in a building with lift and porter. At 2,868
square feet it is the largest apartment in our Mayfair selection and, at £2,266 per square foot,
the cheapest by that measure — but the 102-year lease is the reason, and it should be priced
accordingly.

This is a selection, not the market. Twenty-five properties were available inside this band across the three areas on 4 August 2026 —
twenty-one of them within a USD 10M all-in budget — and off-market instructions are not counted at
all. If none of the above matches your brief, that is the normal starting position for a search
rather than the end of one —
