Serviced offices Marylebone: the building at 33 Cavendish Square
The building is a 1990s office block with large windows, a lift to every floor and a contemporary lobby. It suits firms that want a prime W1 postcode in a practical modern office rather than a period townhouse. Rooms on the upper floors look over Cavendish Square Gardens, and there is a roof terrace for the building’s occupiers.
Each office is a private, lockable room with desks, chairs and storage already in place. Broadband is superfast fibre with a backup line, and IT support is available. The reception is staffed through the working day, post is received and held for you, and the building has CCTV and secure entry around the clock. Meeting rooms can be booked by the hour when you need a larger table or a client presentation.
Clinic rooms and meeting rooms in the building
The building also has CQC-registered consulting and treatment rooms, a few minutes from Harley Street, so a practice can keep its clinic and its administration under one roof. The 33 Cavendish Square page describes the whole building, its offices and its clinic rooms.
Who takes serviced offices in Marylebone
The offices suit teams of two to twenty-five in finance, family offices, law, consultancy and creative and technology firms who want a W1 address and a building of the same standard as the large flexible office brands at a materially lower monthly cost. Rooms are private, so calls stay private and client papers stay out of sight.
Marylebone High Street and Wigmore Street are a short walk for lunch and shopping, Harley Street is round the corner, and Regent’s Park is ten minutes north on foot. Oxford Street is at the end of the square.

A one-desk office is £815 per month plus VAT, and in the larger rooms the price works out from £350 per desk.

There is no separate service charge, no business rates bill and no broadband contract to arrange, because those are in the monthly figure.

Moving into 33 Cavendish Square
Viewings of the serviced offices in Marylebone are usually possible the same day you ask. If the room suits, you sign one agreement for the office and move in as soon as it is ready, with the furniture, broadband and reception already working. There is no fit-out to arrange and nothing to buy. When you outgrow the room you move to a larger one in the building rather than starting the search again, and when you need less space the same applies in reverse.

Cavendish Square sits between Oxford Street and Harley Street, with John Lewis on its south side and the medical district to the north.
