How Much Does It Cost to Upgrade or Expand an Office You Are Already In?

Whether you upgrade or expand an occupied office, the cost is not simply a square metre rate. Four specific drivers do most of the work in moving a budget up or down, and most cost guides skip at least two of them. Getting these right before scoping a project is the difference between an accurate budget and a number that moves once work starts.

Melbourne fitout benchmarking generally spans from around four hundred dollars per square metre for a basic refresh through to well over two thousand five hundred dollars per square metre for a premium build, with JLL citing roughly three thousand and eleven dollars per square metre nationally for a medium quality fitout. Whether you upgrade or expand, where your project lands inside that range comes down to the four drivers below, not the square metre count alone.

Driver One: End of Life Building Services

 

Mechanical and electrical services that are approaching end of life, combined with compliance standards that keep rising, are usually the single largest cost on an upgrade. Air conditioning capacity, switchboard capacity and cabling infrastructure all have a working life, and once that life is up the cost of replacement can dwarf everything else in a scope.

Here is the part most guides miss. For a tenant rather than an owner occupier, this is typically the landlord’s obligation, not the tenant’s. The way to avoid carrying this cost yourself is to raise it early in lease negotiations, well before a renewal is signed, and to trade a longer lease term for the landlord funding the services upgrade. Owner occupiers do not have this option and need to budget for it directly, which makes end of life services an even more important line item to assess before any purchase or long term occupation decision.

 

Driver Two: Furniture for How People Actually Work Now

 

Sit to stand desks across the floor, multiple monitors per desk, and monitor arms to manage the extra hardware add up quickly once they are applied to a full headcount rather than a handful of desks. This driver is frequently underestimated because furniture gets treated as a minor line item late in a budget, when in practice it now represents a meaningful share of total project cost for any workplace upgrading to a genuinely modern desk setup.

Driver Three: AV and Workplace Technology

 

Screens, meeting room technology and the equipment that makes hybrid meetings function properly are a significant and growing cost. As hybrid work has become permanent rather than temporary, the bar for what a functional meeting room needs has risen, and AV budgets that were once an afterthought now need to be scoped with the same rigour as construction trades.

Driver Four: Future Proofed Space Planning

 

Whether you upgrade or expand, the right mix of meeting rooms, quiet spaces, and collaborative or gathering areas is what gives people an actual reason to come into the office rather than work from home. This is a planning cost as much as a construction one. Getting the space plan wrong means paying construction rates for rooms nobody uses, which is a more expensive mistake than any individual finish choice.

Where the Money Actually Goes

 

A useful way to think about the budget to upgrade or expand is that it splits roughly into base building services, furniture and fitout, and technology, rather than being one undifferentiated construction number. Businesses that budget for construction alone and treat furniture and AV as separate, later decisions are the ones most likely to find their true cost has landed well above their first estimate.

Upgrade or Expand: How to Scope This Accurately

 

Start by auditing the condition of existing services before anything else, since this is the driver most likely to move a budget significantly in either direction. If you are a tenant, raise services condition in lease discussions before committing to a term. Then work through furniture, AV and space planning as connected decisions rather than separate purchases, since a space plan drives how much furniture and technology you actually need.

Whether clients upgrade or expand, Agero scopes office fitouts with all four of these drivers assessed up front, rather than pricing construction first and treating furniture and technology as an afterthought. Our design and construct approach means the same team carries the project from scoping through to delivery, which is where most of these cost surprises get caught before they become budget blowouts.
