How much does an office
fitout cost in Perth?

A straight answer, then the detail, from a registered builder who prices and delivers these every week.

As a guide, a commercial office fitout in Perth typically costs between around $450 to $1,200 per square metre. A light refresh sits at the lower end; a high-spec fitout with premium finishes, joinery, full services and furniture sits at the top. The only accurate figure comes from a site walk-through and a fixed-scope quote.

What drives the price

Three things move the number more than anything else:

  • The quality of finishes and joinery you choose
  • The services involved, electrical, data, lighting, heating and cooling
  • The condition of the space and how much base work is needed before the fitout

How to budget accurately

Per-square-metre figures are a starting point, not a quote. The reliable way to budget is a site walk-through where a builder sees the actual space, then a fixed-scope quote that lists exactly what's included. That's what protects you from a beautiful concept that blows out the moment construction starts.

Can a fitout be tax deductible?

Often, yes. Commercial fitout costs are frequently depreciable or deductible for your business, which can offset a meaningful portion of the spend. We're builders, not accountants, so confirm the detail with your accountant, but it's worth factoring in.
