Serviced offices in Victoria rarely combine this much heritage with this much shared space. Alliance House is a restored 1938 Art Deco building offering private office suites in Westminster, SW1H, run directly by owner-operator Imoxis. This serviced office space pairs a staffed reception with flexible terms, making it a strong choice for professional services firms, policy consultancies and growing teams seeking a private office in London with a prestigious address.

St James's Park station, on the District and Circle lines, is a one-minute walk from the door. Victoria station is also close by, placing government departments, professional institutions and client meetings within easy reach for occupiers and visitors alike.

Designed by Murrell and Pigott, the building pairs restrained Art Deco style with black Crittall windows, Portland stone, original terrazzo, pitch-pine herringbone parquet and brass detailing. An Art Deco entrance porch opens into a dual aspect reception and living room, while the oak-panelled Alliance Hall survives as the centrepiece, now home to a generous client kitchen and social space.

Imoxis has given this address more communal space than any other building in its collection, with an entire level reserved for occupiers. Amenities include bookable meeting rooms with video conferencing and complimentary refreshments, breakout areas, a gym, a games room with table tennis and a dedicated music and podcast room. Client events bring the community together, and the reception team is on hand from 8:30am to 6pm alongside 24-hour access every day of the year. Phone booths, cycle storage and showers are being added, with a roof terrace currently under construction. For teams moving on from a conventional lease, the building offers the warmth of a private members' club with the practicality of fully serviced workspace.

Every private office is fully furnished, with tailored fit-out and furniture options for teams wanting a space that reflects their brand. Staffed reception, nightly cleaning, dual fibre internet lines, secure access control and individual climate control are included as standard, keeping day-to-day running costs simple and predictable. Suites are available now and over the coming weeks on flexible terms with simple per-desk pricing, allowing a team to take one office today and move into a larger suite within the same building as headcount grows. Start dates can be agreed to suit each business, with suites ready to occupy shortly after terms are signed. Businesses comparing flexible office space in Victoria, or searching for a private office to rent in London with real period character, can secure a suite quickly. Viewings can be booked at short notice and cover the offices, the client level and Alliance Hall. Enquire through CityFlex today to arrange a viewing and reserve a preferred start date.
