What is a Cat A fit-out?

A Cat A fit-out is ensuring that the space is blankcanvasready but all the essential aspects such as mechanical and electrical works, are supplied and installed to a high standard following all safety regulations. It’s a step up from a shell and core fit but provides basic finishing of the designated office area. It ensures that the foundations of the space are ready for the interior design elements such as the installation of furniture and the application of wallpaper and accessories. Fundamental items such as internal walls, lifts and reception areas are completed as well as raised floors and suspended ceilings with fitted lights and painted perimeter walls.

What is a Cat B fit-out?

A Cat B office fit out is the next level up from a Cat A fit. It takes the blank canvas and basic internal finishes and transforms the space with every design aspect you require. In collaboration with a dedicated interior designer, you’ll discuss and decide on space planning, where to place meeting rooms and breakout spaces, as well as colour schemes and furniture selections. They’re on hand to take on your ideas and produce mood boards and drawings to showcase how the office can be enhanced. They’ll even assist with picking artwork and rugs. A Category B fit can be completed before you move into a new office, or during a time that works best for your schedule when the workforce can operate elsewhere without too much disruption.
