Basepoint is celebrating 20 years since it opened its first business centre in Romsey in 1994 in partnership with Test Valley Borough Council.
Now their 30 UK centres are marking the occasion with commemorative plaques installed on each of its building.
A party was held to mark the occasion during which the mayor of Southampton, Cllr Ivan White, unveiled the plaque at the Southampton centre in Andersons Road.
The company prides itself on providing flexible, serviced and managed offices, virtual offices and meeting rooms to help build small to medium-sized businesses.
