When the view from your office is as stunning as the one from Vistra’s new workplace at 50 Broadway, you don’t want anything to get in the way.

And that’s exactly the approach we took in designing it.

Our fit out works in harmony with the building, delivering light and airy open plan working areas and modern cellular office spaces, all with a clear line of sight to the leafy St. James’s Park outside.

Steeped in history, 50 Broadway was originally constructed in the 1920s as the headquarters of MI6, and was occupied under the guise of the “Minimax Fire Extinguisher Company” to maintain its secrecy.

Vistra’s new home on the 7th floor of the building is so good, we’re sure it won’t remain a secret for long.

Vistra helps businesses that do good, do better. As a leading global fund administrator and corporate service provider, it works with clients who are making a difference in the world, whether they’re developing new technology, new ways of investing or new ways of working.

Behind their work, you’ll find Vistra’s 5,000 professionals managing and securing their entities so they can employ more people, expand into new markets, improve their productivity and structure their businesses more efficiently.


Office Principles was appointed to deliver the first fit out in a commercial building located in the heart of St. James’s Park.

Having recently undergone a comprehensive Grade A landlord refurbishment, 50 Broadway provided a blank canvas on which to creatively apply Vistra’s vision for a workplace that would excite its 40-strong team and entertain its clients.

As the building was vacant during works, our only significant challenge was in delivering the brief within budget, without compromising on the quality of design whilst remaining on brand / whilst bringing the brand to live in a 3D environment.

The success of Vistra’s new London office owes much to its simplicity.

Crisp, white walls and a long corridor run through the space to the glazed balcony outside, framing the exceptional exterior view and knitting all parts of the workplace together.

Stand anywhere within this workspace and you will be bathed in light and free from the dark or gloomy areas that often blight traditional office spaces.

Taking advantage of the building’s shallow floor plate, our design delivers both privacy and ease of access.

It’s also clean, slick and highly practical too. Take the flexible boardroom design, with its sliding folding partitions and adjusting tables that enable the space to be tailored to changing requirements.

There is desking and open plan collaborative areas for employees, as well as cellular office space and functional areas - including three separate ‘Zoom rooms’ - for focused work and client calls.

An eye-catching island unit provides a central focal point in the breakout area, with canteen-style tables and access to the wraparound balcony.

Elsewhere, a raw, steel shelving unit - inspired by the company’s logo - greets visitors on arrival and contrasts with the modernity of the state-of-the-art TV screens available throughout. LED desk lighting adds interest and elegance, while lockable storage ties in with the minimalist look.

Furniture is strategically deployed to screen spaces while materials cleverly link different parts of the office, with herringbone flooring and slatted feature walls dovetailing with pendant lighting, glass whiteboards and textured wallpaper.

We even got Vistra’s team involved in the design process, putting a series of potential feature colours to a popular vote. The bold greens and blues, and a subtle red tone are all featured within high-energy areas of the office and complement the cool, neutral colour palette that adorns much of the space.

This is a fabulous new office that provides the very best combination of workplace settings and social spaces, with the flexibility to change shape for larger meetings and entertaining clients. Our design has been shaped around a desire to capture the incredible view from this seventh floor space, with a clear line of sight wherever you stand. “We have thoroughly enjoyed working in collaboration with the team at Vistra. They have been appreciative of our solutions-driven approach and have been extremely welcoming and open to compromise throughout.

Tom Parsons, Sales Director, Office Principles

With our new London office, we wanted a space that could support our hybrid working model, encourage greater collaboration and support client events. Not an easy task! “We were impressed with the team at Office Principles from the first meeting and in particular their collaborative approach and attention to detail. This continued through final designs and implementation, all delivered on time and to a high standard.
