What is a CAT A fit out?

A Cat A fit out will provide a basic level of furnishing, typically referred to as the shell and core. This process will include raised floors, suspended ceilings and internal surfaces, along with basic mechanical and electrical services which need to be put in place before any decoration can take place. While Cat A spaces will have the floor and walls in place, they’ll be quite basic and are often finished in an industrial style. It’s worth bearing in mind that a landlord may request for the space to be returned back to them in Cat A condition at the end of the tenancy so this something to check before going ahead with any plans. Our Cat A services include:

  • Raised flooring and suspended ceiling work
  • Mechanical and electrical services
  • Fire protection and health and safety
  • Air conditioning and ventilation
  • Mezzanine flooring
  • Office and industrial partitioning

The difference between Cat A and Cat B fit outs

When contacting us for a refurbishment project, knowing whether it’s a Cat A or Cat B will help everyone out and help us to create the right plans and get straight to work. There are a few different types of office fit outs available, each one offering their own qualities and purposes. A Cat A fit out is a space that is completely functional but is bare of items such as furniture, materials and partitions. Finishings that may already be in place include air conditioning, heating or lighting. A Cat B office fit out comes after the Cat A and is where a space has been tailored to the customers specific needs. The customer will then have all of the features that they asked for including design, furniture and finishing touches. Whether you require a Cat A or Cat B will depend on the environment and ground you already have in place. For example if you’re starting fresh with a new business venture, both these processes will be needed to take the space from planning to final use.

For a deeper understanding and to know which service your business needs, have a read through our blog on the difference between a Cat a and Cat B fit out.
