Welcome to

The Observatory

One of the historic landmarks of London’s West End and now a prestigious business premises.

Here at The Observatory, 10 Argyll Street, the surveyor Major General William Roy carried out many of the observations and calculations that led to the accurate mapping of the United Kingdom.

Today, the address is even better connected.

Just meters from Oxford Circus, which benefits from London Underground and the new Elizabeth Line (Crossrail) service, there are excellent links to every major central London rail terminus and onward connections to Heathrow, Gatwick and Stansted. The Observatory has not just London but the world in its sights.

Behind a perfectly preserved classical Georgian façade, at the intersection of Soho, Mayfair, Marylebone and Fitzrovia, in a prime office location well served by International brands and businesses, you will find five floors of the most contemporary, well equipped, environmentally friendly and energy efficient, and the best-connected office space in London.
