What is an Office Fit Out?

An office fit-out is the complete process of transforming a raw or outdated space into a fully functioning workplace, designed around how your people actually work. It covers everything from space planning, partitioning, and M&E infrastructure through to finishes, furniture, and technology, turning an empty shell or tired office into an environment that supports productivity, culture, and growth.

The scope and investment of a fit-out depend on where you’re starting from. A shell-and-core space needs everything from the ground up. A Cat A fit-out delivers the base-build essentials: raised floors, suspended ceilings, basic mechanical and electrical services. A Cat B fit-out is where the space truly becomes yours: the layout, branding, meeting rooms, breakout areas, and all the details that reflect how your team operates day to day.

PJT Partners Fit Out at One Curzon Street

K2 Space partnered with PJT Partners, a leading global investment bank, to design and fit out their London headquarters at One Curzon Street in Mayfair. As part of a decade-long relationship delivering multiple phases of the building, K2 was asked to design and fit out the second floor, extending the refined aesthetic of the existing floors while introducing a broader mix of workspace settings.

Spanning 60,000 sq. ft., the design takes its influence from PJT’s New York office, with light woods and neutral tones that support the strong task focus of the business. The reception sets the tone immediately: a sweeping timber ceiling feature with integrated LED lighting curves above a marble-clad desk, with a seating area beyond that feels more private members’ club than corporate lobby.

At the heart of the floor is a café and lounge zone that doubles as the firm’s social hub. A curved oak-slatted wall wraps the tea point on one side while creating an intimate lounge on the other, with banquette seating and espresso machines set beneath an arched timber surround. Breakout spaces like these were central to PJT’s way of working, encouraging the informal meetings and social interaction that matter in an advisory business.

The transition from social to focused zones is deliberate, with pale oak walkways giving way to woven carpet tiles as the environment quietens. Glass-fronted private offices line the perimeter, each with its own informal meeting setting, while meeting rooms fitted with the latest conferencing technology connect teams across PJT’s global offices.

Bringing "One Dentsu" to Edinburgh's Princes Street

K2 Space partnered with Dentsu, one of the world’s largest integrated marketing and communications networks, to design and fit out their Edinburgh office at The Stamp Office on Princes Street. The brief was to bring multiple teams under one roof in a space that embodied the “One Dentsu” philosophy, while respecting the character of a listed Georgian building that has stood on Edinburgh’s central thoroughfare since 1819.

Spanning 7,000 sq. ft., the open-concept layout uses the building’s natural zoning to give each team its own identity without fragmenting the floor. K2 worked closely with the local team to develop a design brief that balanced the needs of individual groups with a cohesive visual language, integrating period features rather than working against them. Soft pastels and considered lighting run throughout, grounding the space in a palette that feels contemporary without competing with the classical architecture.

Sustainability shaped the project from the outset. In line with Dentsu’s ERG guidelines, as much furniture as possible was reused, with some pieces sourced from other Dentsu UK sites to minimise waste and extend asset lifecycles. K2 integrated these items so seamlessly that the space reads as entirely new. Modular meeting pods were specified for acoustic privacy and future flexibility, allowing the layout to evolve without costly demolition or construction.

Client visits are central to how Dentsu works, so the space needed to welcome external partners into the creative process. A reception area on entry sets the tone, while a bright lounge and workshop space on the small mezzanine gives teams a semi-private zone for developing client-specific campaigns, connected to the wider floor but with enough separation to focus. An elegant coffee area doubles as an informal meeting zone, giving the team somewhere to step away, recharge, and connect with colleagues and clients outside of their immediate workspace.

Inspiring and Sustainable Office Fit-Out for DTRE in London’s Mayfair

K2 Space partnered with leading property advisor DTRE to deliver an inspiring and highly sustainable office fit-out in the heart of London’s Mayfair. Spanning 11,000 sq. ft., the project was driven by a vision to create a space that would energise employees, impress clients, and embody DTRE’s forward-thinking approach to property and sustainability.

The new workplace achieved a BREEAM “Very Good” accreditation, the highest level attainable within the building, through meticulous monitoring of energy, water, waste, and supply chain processes. With features such as extensive biophilic design elements, a client “touch-down” area, an auditorium with bleacher seating, and a barista-style reception, the space combines functionality, flexibility, and wellbeing in perfect harmony.
