How much does a 20 person office cost in Adelaide?
Sidespace's live listing data puts a 20 person serviced office in Adelaide at about $16,200 per month all-inclusive, a median of $810 per desk per month across 5 priced offices sized 11-20 desks (October 2026).
Twenty people needs 160 to 240 square metres and changes the maths. At this size a traditional lease becomes genuinely competitive with flex for the first time, because the fit-out cost spreads across enough desks to pay for itself over a three-year term. Most twenty-person teams end up comparing a fitted commercial suite against a managed office, not against coworking.

What 20 people actually need
Run both numbers before you commit. A serviced suite at twenty desks is one predictable monthly figure; a lease is a lower base rent plus fit-out, furniture, internet, cleaning and outgoings. Whichever way it lands, twenty desks is enough volume that operators will move on price.
Allow 160 to 240 square metres, and budget $194,400 a year all-inclusive before any incentive on term. Best suited to scaling companies, established agencies, regional headquarters, professional firms with client-facing space.
Figures exclude POA listings and indicative guide pricing, so every rate above is one an operator published. Medians are drawn from offices sized 11-20 desks, the band a 20 person team sits in, and bands below three offices are never published.
