Office Interior Fit Out in London
Fusion are experts in blending furniture and ways of working with building services and layout design to achieve a balanced, considered, office interior appropriate to the budget, the objectives and the timescale. Integrating furniture into an office design and fit out scheme makes the most of opportunities to integrate service, space and functions, and unifies a project both for effective timelines and elimination of clashes, cost problems and miscommunication.
End-to-end design and office fit delivers the most accomplished results, both in terms of cost-control, cohesion and program. The Fusion approach is to have a single contact leading the project at the design stage right through to management of the works. The advantage of this is to convey all the concept design thoughts, ideas, and agreed actions into the physical build, ensuring nothing gets diluted in translation. All too often projects are built in ways that fail to capture the design intent. With Fusion the office design is delivered into the physical fit-out by someone immersed in the office design phase.

Frequently Asked Questions
Office fit out 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 to a very high quality level.
Category A fit Outs are usually undertaken for landlords, developers or institutional investors, with the main 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.
