Our scope of work covers every element of office interiors, external refurbishment, and even the design of key work processes such as filing systems and collaborative team working areas.

Dilapidation works on your existing space
Fit out services in your new office space (including Cat B fit outs)

Office fit out in London is the process of making interior spaces suitable for occupation and is different from the actual structural work relating to the building fabric.
Typical Office fit-out costs range from £39 per square foot (£420 per square metre) for an office interior fit-out or refurb for Cat B works to £75 per square foot (£800 per square metre) for a project that includes a significant upgrade to the building ventilation systems or a very high-quality level.
Category A fit Outs are usually undertaken for landlords, developers or institutional investors, with the primary objective being to ‘prepare the building, so it is ready for the end-user client’.
What people will usually refer to as the exciting part of fitting out an office is known as a Cat B fitout, the fitting out of the internal space. A Category B office fitout will usually be carried out alongside an expert team or directly with the workspace occupier to design a custom workplace solution to suit their needs.
Learn more about the differences here.
An office fit out is the process of taking a blank or shell space and making it ready for occupation. This can include everything from space planning, installing partitions, ceilings, flooring, HVAC systems, lighting, and office furniture. Fit outs are common in new office developments, where the landlord provides a basic shell, and the incoming tenant completes the final Cat A or Cat B fit out to create a functional workspace that reflects their company culture and business objectives.
An office refurbishment, on the other hand, focuses on revitalising or upgrading an existing office space. Rather than starting with an empty shell, refurbishment means working with your current environment to modernise layouts, introduce new design elements, improve wellbeing and productivity, and often upgrade furniture solutions or finishes. It provides many of the benefits of moving into a new office, but without the cost, disruption, or complications of relocating.
In short, fit out creates a new space from scratch, while refurbishment transforms your existing space into something better aligned with your people, brand identity, and future growth.
