No. 14 The house

Five floors,
read downwards.

The Ellerby is one house, not a chain of rooms with a lobby attached.

It was built in 1802 as a private residence and it still behaves like one: you are let in at the door rather than checked in at a desk, the drawing room is a room you sit in, and the card room downstairs is the size of a card room, not a hall. Nothing is open all night except the porter.

R Roof garden

Above the
chimney line.

Six clipped bays in lead planters, a long bench, and the backs of half of Mayfair. Open from noon until the light goes. Residents and their guests only — it seats fourteen, so it fills.

The Long Bar

Short list, long memory. English vermouth, a proper martini, and whatever the barman has been steeping in the back room this month.

See the list

1 The Dining Room

Dinner on the
piano nobile.

Forty covers under the original plasterwork. British produce, cooked plainly and seasoned properly — a kitchen with nothing to prove.

A discretionary 12.5% service charge is added. Menus change with the market.

G The hall

Let in,
not checked in.

There is no desk. The porter opens the door, takes your bag and shows you up. Everything else is arranged from a chair.

LG The Card Room · adults 18+

Eight tables,
under the street.

A single vaulted room beneath the pavement, panelled and quiet. Eight tables, one bar, no machines and no music. It is a room for playing cards in, and it closes at two.

W1 On foot

Everything worth
walking to.

Mayfair is small. The porter will draw you a route on the back of a card, but these three are the ones we send people on.

6 minutes on foot

The squares

Berkeley to Grosvenor by the back streets, under plane trees that were planted before the house was built.

11 minutes on foot

Green Park at dusk

In at Bolton Street, out at the Mall. Deckchairs in summer, and the best light in London in October.

14 minutes on foot

The auction rooms

Viewings are free and open to anyone. Go on a preview day and handle things you have no intention of buying.

2 nights The Marchmont Weekend

The whole house,
in two days.

Our most-taken stay: a room on the third floor, both meals that matter, and the run of the vaults.

? Enquiries

Before

What this page is, who may go downstairs, and how gambling is handled in the United Kingdom.

No. The Ellerby is an invented London townhouse hotel, written to demonstrate UK-focused hotel and casino content in a responsive page. It takes no bookings, holds no licence and processes no payments. The address, rates and menus are all fictional.

Adults aged 18 and over. In Great Britain the minimum age for casino gambling is 18, and photo ID is checked at the door under the Think 21 approach used across the industry. In this concept, membership is not required — that requirement was removed from British casinos in 2005.

Yes. Any real premises offering casino games in Great Britain must hold an operating licence from the Gambling Commission and a premises licence from the local authority, and staff must hold personal licences. This page is a design demonstration and holds none of them.

No. The card room is one room on one floor, open four hours a night. Most guests never go down. The hotel is a hotel first, and nothing about the stay assumes you will play.

Set a limit in money and in time before you start, and use only money you can afford to lose. Never borrow to play and never try to win back what you have lost. If it stops being enjoyable, stop. In Great Britain you can also self-exclude from all licensed online operators through GAMSTOP, and from individual premises directly.

18+

Take time to think.

Gambling carries real financial risk and is not a way to make money. Set limits before you start, take regular breaks, never gamble with borrowed money, and stop if it stops being fun. If gambling is causing harm to you or someone close to you, free, confidential help is available in the UK at any hour — you do not need to be in crisis to call.
