33 Cavendish Square

33 Cavendish Square sits on one of Marylebone’s landmark garden squares, in the heart of London’s West End. The building combines period character with fully managed modern workspace, and houses both serviced offices and CQC-registered clinical rooms — so a practice can take consulting space and administrative space under one roof.

Serviced offices at 33 Cavendish Square

Offices are furnished and move-in ready, ranging from a single desk for a consultant or founder up to private suites for an established team. Superfast fibre with back-up, utilities, business rates, cleaning, staffed reception, mail handling, meeting-room access and 24/7 secure entry are all included in one monthly payment, on terms that flex as you grow. The building also has a 45-metre roof terrace, kitchens and breakout space.

Clinical and consulting rooms near Harley Street

The building offers CQC-registered clinical rooms suitable for consultants, aesthetic practitioners, therapists and allied health professionals. Rooms can be taken by the day, by the session or on a regular weekly basis, which makes 33 Cavendish Square a practical alternative to a permanent Harley Street lease while keeping you inside the same medical district.

Getting here

Oxford Circus (Central, Bakerloo and Victoria lines) is roughly a two-minute walk. Bond Street adds the Elizabeth line for fast connections to the City, Canary Wharf and Heathrow, and Great Portland Street and Regent’s Park are both close by. The West End’s shops, restaurants and hotels are immediately to the south, while the garden square itself gives the address a quieter setting than a main-road building.

Who the building suits

Occupiers here are typically small professional firms, consultancies and international businesses opening a London base, alongside private medical and aesthetic practitioners who want a compliant room in a credible medical location without the overheads of their own premises. The W1G postcode does a lot of work when clients look you up.
