What You Need to Know about Commercial Fit Out Construction

Commercial fit out construction is an essential aspect of creating or refurbishing commercial spaces, such as offices, retail stores, restaurants, and more. It involves the design, construction, and finishing of interior spaces to meet the specific requirements of the business occupying the space. As a business owner or property manager, you should know the ins and outs of commercial fit out construction to ensure the success of your project.

1. Categories of Commercial Fit Out

There are three main categories of commercial fit outs, which differ based on the extent of work required and the level of customisation involved. These are:

  • Shell and Core: This type of fit out involves the construction of the building’s basic structure, including the external walls, floors, and ceilings. The interior spaces are left as a blank canvas for the tenant to customise according to their needs.
  • Category A Fit Out: This is a basic level of interior fit out, which includes essential elements such as suspended ceilings, raised floors, basic mechanical and electrical services, and internal surface finishes. It provides a functional space for the tenant to build upon.
  • Category B Fit Out: This is a fully customised interior fit out tailored to the specific requirements of the tenant. It includes the installation of partition walls, bespoke joinery, specialised lighting, and other custom features that bring the space to life.

2. Stages of Commercial Fit Out Construction

The commercial fit out construction process typically involves the following stages:

  • Design and Planning: This stage involves working with architects, interior designers, and other professionals to create a detailed plan for the fit out. It includes space planning, selecting materials and finishes, and designing any custom elements.
  • Building Control Approval: Before beginning construction, it’s essential to obtain the necessary permits and approvals from the local building control authority. This ensures that the fit out project complies with building regulations and safety standards.
  • Demolition and Strip Out: If the project involves refurbishing an existing space, the first step is to remove any unwanted fixtures, fittings, and finishes. This prepares the site for the new fit out construction.
  • Construction and Installation: Once the site is prepared, the construction phase begins. This involves the installation of walls, ceilings, floors, and other structural elements, as well as the electrical, plumbing, and HVAC systems.
  • Finishing Touches: With the construction complete, it’s time to add the final touches. This includes painting, installing fixtures and fittings, and adding any custom elements, such as signage or artwork.
  • Handover and Defects Period: Once the fit out is complete, the contractor will hand over the space to the tenant. There is usually a defects liability period, during which the contractor is responsible for addressing any issues.

3. Factors to Consider When Choosing a Commercial Fit Out Contractor

Selecting the right contractor is crucial for the success of your commercial fit out project. Here are some factors to consider when making your choice:

  • Experience and Track Record: Look for a contractor with a proven track record in successfully completing similar projects. They should have experience working with businesses in your industry and be familiar with the specific requirements and challenges involved.
  • Quality of Work: Ensure that the contractor is committed to delivering high-quality workmanship and uses high-quality materials. This will help ensure the longevity and functionality of your fit out.
  • Communication and Collaboration: Choose a contractor who is easy to communicate with and is willing to collaborate closely with you and your design team. This will help ensure that your vision for the space is realised.
  • Budget and Timeline: Ensure the contractor can deliver the project within your budget and on time. It’s essential to establish a clear timeline and budget from the outset to avoid any unexpected surprises.


Commercial fit out construction is a complex process that requires careful planning, coordination, and execution. By understanding the different categories, stages, and factors involved in selecting a contractor, you can ensure that your project is a success. The result will be a functional and attractive space that meets the needs of your business and enhances the overall customer experience!
