How much does a 20 person office cost in Adelaide?

A 20 person serviced office in Adelaide costs about $16,200 per month all-inclusive — a median of $810 per desk per month across 7 priced offices sized 11-20 desks currently listed with us.

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 negotiated 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.

20 person offices in Adelaide, frequently asked

How much does a 20 person office cost in Adelaide?
A 20 person serviced office in Adelaide costs about $16,200 per month all-inclusive, based on a median of $810 per desk per month across 7 priced offices sized 11-20 desks currently listed with us.
