Mayfair · Belgravia · Chelsea · Kensington
Period houses in London’s garden squares, sold privately since 1891.
The firm
Four generations of the same families have bought and sold their London houses through us. We know which squares keep a waiting list for garden keys, which leases have eighty years left, and which owners would sell to the right buyer. We keep all of it to ourselves.
Georgian and Regency townhouses, mansion flats and mews in six London postcodes. Seven in ten of our sales are agreed before a house is ever advertised, so owners keep their privacy and buyers see houses the portals never will.

For sale
Six houses we can show you this season.
Everything else we are selling is offered only to buyers on our register. These can be seen by appointment, usually within the week, with the partner who is selling them.

The Private Office
Seven in ten of our houses are sold before they are advertised.
Owners come to us so the house is never seen on a portal. Buyers come because the houses they want rarely reach one. A private sale is how both get what they came for.
- I
A partner values the house in person
One of our six partners walks every floor with you, then writes to you with two figures: what the house will fetch privately, and what it might fetch on the open market.
- II
We write to the buyers it suits
Our register holds 412 buyers we have met and whose finance we have seen. For a typical house, eight to twelve of them hear about it, by letter or by telephone, and nobody else does.
- III
Viewings by appointment, never a board
No photographs online and no board at the railings. If the house has not sold privately in six weeks, you decide whether it goes to the open market, and we take it there.
Neighbourhoods
Six postcodes, known house by house.
We work nowhere else, so we know who owns what, what it last sold for and what it would take for it to sell again. Prices are our own achieved averages over the last twelve months.

My grandfather bought the house through Whitmore & Finch in 1954. Seventy years later they sold it for us in nine days, and nobody on the square knew until the removal vans came.

Since 1891
Still on Mount Street, still a partnership.
We have never had a shareholder, a franchise or a second office. The partners own the firm, sell the houses and answer the telephone, and the ledgers the first houses were entered in are still on the shelf behind the front desk.
