Marbella's office market is small and tied to the service economy of the Costa del Sol — property, legal, hospitality and private wealth rather than corporate occupiers. Listed supply matches that scale exactly: 1 building, Avenida Ricardo Soriano 72, with 10 suites. Avenida Ricardo Soriano is the artery running from Marbella's old town toward Puerto Banús, which is why it carries most of the town's professional addresses.
Suite sizes in Marbella run from 5 m² to 90 m², with the median at 38 m². The 90 m² figure is the practical ceiling of the current set, so a larger requirement has to be built from more than one unit at the same address; for most incoming firms the 38 m² median is the realistic planning figure for a first office in Marbella.
Ten suites in one building leaves a Marbella tenant nothing to trade on location — every option shares the same lobby, the same street frontage and the same parking arrangement. Comparison moves instead to floor level, outlook and fit-out across the 10 units, and to what the rate quoted in € per m² a year actually includes. In a market this shallow the service package, not the address, is where the negotiating room sits.
