Office Fit Out Contractors will generally provide estimated costs per Sq. Ft, so it is crucial that you know the dimensions and size of your new space, while the per Sq. Ft cost will depend on a number of factors, including:

  • The state of the mechanical and electrical (M&E) systems servicing the space i.e. heating, ventilation, power supply etc. If the M&E is old or not in working order, it can be a costly exercise to install new systems, so it worth appraising the M&E of any shortlisted space
  • Does the space have a raised floor? This can impact costs as a raised floor allows for optimum power supply and distribution management, allowing all cabling to remain hidden underneath. Not having a raised floor can mean that fit out costs can increase as more innovative solutions are required, or a raised floor needs to be installed
  • How old is the building and/or it a listed building? There can tend to be complications with older buildings as normal wear and tear can take its toll, while if the space is within a listed building, there can be an increased level of paperwork required before any fit out can begin which can impact costs
  • Ultimately, office fit out costs are heavily influenced by the specification required by the company moving into the new space, whether they desire high spec finishes, fixtures and furniture
